v1.22.2

Improvements

• Expanded and clarified NodeTraversor support for in-place DOM rewrites during NodeVisitor.head(). Current-node edits such as remove, replace, and unwrap now recover more predictably, while traversal stays within the original root subtree. This makes single-pass tree cleanup and normalization visitors easier to write, for example when unwrapping presentational elements or replacing text nodes as you walk the DOM. #​2472
• Documentation: clarified that a configured Cleaner may be reused across concurrent threads, and that shared Safelist instances should not be mutated while in use. #​2473
• Updated the default HTML TagSet for current HTML elements: added dialog, search, picture, and slot; made ins, del, button, audio, video, and canvas inline by default (Tag#isInline(), aligned to phrasing content in the spec); and added readable Element.text() boundaries for controls and embedded objects via the new Tag.TextBoundary option. This improves pretty-printing and keeps normalized text from running adjacent words together. #​2493

Bug Fixes

• Android (R8/ProGuard): added a rule to ignore the optional re2j dependency when not present. #​2459
• Fixed a NodeTraversor regression in 1.21.2 where removing or replacing the current node during head() could revisit the replacement node and loop indefinitely. The traversal docs now also clarify which inserted nodes are visited in the current pass. #​2472
• Parsing during charset sniffing no longer fails if an advisory available() call throws IOException, as seen on JDK 8 HttpURLConnection. #​2474
• Cleaner no longer makes relative URL attributes in the input document absolute when cleaning or validating a Document. URL normalization now applies only to the cleaned output, and Safelist.isSafeAttribute() is side effect free. #​2475
• Cleaner no longer duplicates enforced attributes when the input Document preserves attribute case. A case-variant source attribute is now replaced by the enforced attribute in the cleaned output. #​2476
• If a per-request SOCKS proxy is configured, jsoup now avoids using the JDK HttpClient, because the JDK would silently ignore that proxy and attempt to connect directly. Those requests now fall back to the legacy HttpURLConnection transport instead, which does support SOCKS. #​2468
• Connection.Response.streamParser() and DataUtil.streamParser(Path, ...) could fail on small inputs without a declared charset, if the initial 5 KB charset sniff fully consumed the input and closed it before the stream parse began. #​2483
• In XML mode, doctypes with an internal subset, such as <!DOCTYPE root [<!ENTITY name "value">]>, now round-trip correctly. The subset is preserved as raw text only; entities are not expanded and external DTDs are not loaded. #​2486

Build Changes

• Migrated the integration test server from Jetty to Netty, which actively maintains support for our minimum JDK target (8). #​2491

v1.22.1

Improvements

• Added support for using the re2j regular expression engine for regex-based CSS selectors (e.g. [attr~=regex], :matches(regex)), which ensures linear-time performance for regex evaluation. This allows safer handling of arbitrary user-supplied query regexes. To enable, add the com.google.re2j dependency to your classpath, e.g.:

 <dependency>
 <groupId>com.google.re2j</groupId>
 <artifactId>re2j</artifactId>
 <version>1.8</version>
 </dependency>

(If you already have that dependency in your classpath, but you want to keep using the Java regex engine, you can disable re2j via System.setProperty("jsoup.useRe2j", "false").) You can confirm that the re2j engine has been enabled correctly by calling org.jsoup.helper.Regex.usingRe2j(). #​2407

• Added an instance method Parser#unescape(String, boolean) that unescapes HTML entities using the parser's configuration (e.g. to support error tracking), complementing the existing static utility Parser.unescapeEntities(String, boolean). #​2396
• Added a configurable maximum parser depth (to limit the number of open elements on stack) to both HTML and XML parsers. The HTML parser now defaults to a depth of 512 to match browser behavior, and protect against unbounded stack growth, while the XML parser keeps unlimited depth by default, but can opt into a limit via org.jsoup.parser.Parser#setMaxDepth. #​2421
• Build: added CI coverage for JDK 25 #​2403
• Build: added a CI fuzzer for contextual fragment parsing (in addition to existing full body HTML and XML fuzzers). oss-fuzz #​14041

Changes

• Set a removal schedule of jsoup 1.24.1 for previously deprecated APIs.

Bug Fixes

• Previously cached child Elements of an Element were not correctly invalidated in Node#replaceWith(Node), which could lead to incorrect results when subsequently calling Element#children(). #​2391
• Attribute selector values are now compared literally without trimming. Previously, jsoup trimmed whitespace from selector values and from element attribute values, which could cause mismatches with browser behavior (e.g. [attr=" foo "]). Now matches align with the CSS specification and browser engines. #​2380
• When using the JDK HttpClient, any system default proxy (ProxySelector.getDefault()) was ignored. Now, the system proxy is used if a per-request proxy is not set. #​2388, #​2390
• A ValidationException could be thrown in the adoption agency algorithm with particularly broken input. Now logged as a parse error. #​2393
• Null characters in the HTML body were not consistently removed; and in foreign content were not correctly replaced. #​2395
• An IndexOutOfBoundsException could be thrown when parsing a body fragment with crafted input. Now logged as a parse error. #​2397, #​2406
• When using StructuralEvaluators (e.g., a parent child selector) across many retained threads, their memoized results could also be retained, increasing memory use. These results are now cleared immediately after use, reducing overall memory consumption. #​2411
• Cloning a Parser now preserves any custom TagSet applied to the parser. #​2422, #​2423
• Custom tags marked as Tag.Void now parse and serialize like the built-in void elements: they no longer consume following content, and the XML serializer emits the expected self-closing form. #​2425
• The <br> element is once again classified as an inline tag (Tag.isBlock() == false), matching common developer expectations and its role as phrasing content in HTML, while pretty-printing and text extraction continue to treat it as a line break in the rendered output. #​2387, #​2439
• Fixed an intermittent truncation issue when fetching and parsing remote documents via Jsoup.connect(url).get(). On responses without a charset header, the initial charset sniff could sometimes (depending on buffering / available() behavior) be mistaken for end-of-stream and a partial parse reused, dropping trailing content. #​2448
• TagSet copies no longer mutate their template during lazy lookups, preventing cross-thread ConcurrentModificationException when parsing with shared sessions. #​2453
• Fixed parsing of <svg> foreignObject content nested within a <p>, which could incorrectly move the HTML subtree outside the SVG. #​2452

Internal Changes

• Deprecated internal helper org.jsoup.internal.Functions (for removal in v1.23.1). This was previously used to support older Android API levels without full java.util.function coverage; jsoup now requires core library desugaring so this indirection is no longer necessary. #​2412

v1.21.2

Changes

• Deprecated internal (yet visible) methods Normalizer#normalize(String, bool) and Attribute#shouldCollapseAttribute(Document.OutputSettings). These will be removed in a future version.
• Deprecated Connection#sslSocketFactory(SSLSocketFactory) in favor of the new Connection#sslContext(SSLContext). Using sslSocketFactory will force the use of the legacy HttpUrlConnection implementation, which does not support HTTP/2. #​2370

Improvements

• When pretty-printing, if there are consecutive text nodes (via DOM manipulation), the non-significant whitespace between them will be collapsed. #​2349.
• Updated Connection.Response#statusMessage() to return a simple loggable string message (e.g. "OK") when using the HttpClient implementation, which doesn't otherwise return any server-set status message. #​2356
• Attributes#size() and Attributes#isEmpty() now exclude any internal attributes (such as user data) from their count. This aligns with the attributes' serialized output and iterator. #​2369
• Added Connection#sslContext(SSLContext) to provide a custom SSL (TLS) context to requests, supporting both the HttpClient and the legacy HttUrlConnection implementations. #​2370
• Performance optimizations for DOM manipulation methods including when repeatedly removing an element's first child (element.child(0).remove(), and when using Parser#parseBodyFragement() to parse a large number of direct children. #​2373.

Bug Fixes

• When parsing from an InputStream and a multibyte character happened to straddle a buffer boundary, the stream would not be completely read. #​2353.
• In NodeTraversor, if a last child element was removed during the head() call, the parent would be visited twice. #​2355.
• Cloning an Element that has an Attributes object would add an empty internal user-data attribute to that clone, which would cause unexpected results for Attributes#size() and Attributes#isEmpty(). #​2356
• In a multithreaded application where multiple threads are calling Element#children() on the same element concurrently, a race condition could happen when the method was generating the internal child element cache (a filtered view of its child nodes). Since concurrent reads of DOM objects should be threadsafe without external synchronization, this method has been updated to execute atomically. #​2366
• When parsing HTML with svg:script elements in SVG elements, don't enter the Text insertion mode, but continue to parse as foreign content. Otherwise, misnested HTML could then cause an IndexOutOfBoundsException. #​2374
• Malformed HTML could throw an IndexOutOfBoundsException during the adoption agency. #​2377.

v1.21.1

Changes

• Removed previously deprecated methods. #​2317
• Deprecated the :matchText pseduo-selector due to its side effects on the DOM; use the new ::textnode selector and the Element#selectNodes(String css, Class type) method instead. #​2343
• Deprecated Connection.Response#bufferUp() in lieu of Connection.Response#readFully() which can throw a checked IOException.
• Deprecated internal methods Validate#ensureNotNull (replaced by typed Validate#expectNotNull); protected HTML appenders from Attribute and Node.
• If you happen to be using any of the deprecated methods, please take the opportunity now to migrate away from them, as they will be removed in a future release.

Improvements

• Enhanced the Selector to support direct matching against nodes such as comments and text nodes. For example, you can now find an element that follows a specific comment: ::comment:contains(prices) + p will select p elements immediately after a <!-- prices: --> comment. Supported types include ::node, ::leafnode, ::comment, ::text, ::data, and ::cdata. Node contextual selectors like ::node:contains(text), :matches(regex), and :blank are also supported. Introduced Element#selectNodes(String css) and Element#selectNodes(String css, Class nodeType) for direct node selection. #​2324
• Added TagSet#onNewTag(Consumer<Tag> customizer): register a callback that’s invoked for each new or cloned Tag when it’s inserted into the set. Enables dynamic tweaks of tag options (for example, marking all custom tags as self-closing, or everything in a given namespace as preserving whitespace).
• Made TokenQueue and CharacterReader autocloseable, to ensure that they will release their buffers back to the buffer pool, for later reuse.
• Added Selector#evaluatorOf(String css), as a clearer way to obtain an Evaluator from a CSS query. An alias of QueryParser.parse(String css).
• Custom tags (defined via the TagSet) in a foreign namespace (e.g. SVG) can be configured to parse as data tags.
• Added NodeVisitor#traverse(Node) to simplify node traversal calls (vs. importing NodeTraversor).
• Updated the default user-agent string to improve compatibility. #​2341
• The HTML parser now allows the specific text-data type (Data, RcData) to be customized for known tags. (Previously, that was only supported on custom tags.) #​2326.
• Added Connection#readFully() as a replacement for Connection#bufferUp() with an explicit IOException. Similarly, added Connection#readBody() over Connection#body(). Deprecated Connection#bufferUp(). #​2327
• When serializing HTML, the < and > characters are now escaped in attributes. This helps prevent a class of mutation XSS attacks. #​2337
• Changed Connection to prefer using the JDK's HttpClient over HttpUrlConnection, if available, to enable HTTP/2 support by default. Users can disable via -Djsoup.useHttpClient=false. #​2340

Bug Fixes

• The contents of a script in a svg foreign context should be parsed as script data, not text. #​2320
• Tag#isFormSubmittable() was updating the Tag's options. #​2323
• The HTML pretty-printer would incorrectly trim whitespace when text followed an inline element in a block element. #​2325
• Custom tags with hyphens or other non-letter characters in their names now work correctly as Data or RcData tags. Their closing tags are now tokenized properly. #​2332
• When cloning an Element, the clone would retain the source's cached child Element list (if any), which could lead to incorrect results when modifying the clone's child elements. #​2334

v1.20.1

Changes

• To better follow the HTML5 spec and current browsers, the HTML parser no longer allows self-closing tags (<foo />)
  to close HTML elements by default. Foreign content (SVG, MathML), and content parsed with the XML parser, still
  supports self-closing tags. If you need specific HTML tags to support self-closing, you can register a custom tag via
  the TagSet configured in Parser.tagSet(), using Tag#set(Tag.SelfClose). Standard void tags (such as <img>,
  <br>, etc.) continue to behave as usual and are not affected by this
  change. #​2300.
• The following internal components have been deprecated. If you do happen to be using any of these, please take the opportunity now to migrate away from them, as they will be removed in jsoup 1.21.1.
  • ChangeNotifyingArrayList, Document.updateMetaCharsetElement(), Document.updateMetaCharsetElement(boolean), HtmlTreeBuilder.isContentForTagData(String), Parser.isContentForTagData(String), Parser.setTreeBuilder(TreeBuilder), Tag.formatAsBlock(), Tag.isFormListed(), TokenQueue.addFirst(String), TokenQueue.chompTo(String), TokenQueue.chompToIgnoreCase(String), TokenQueue.consumeToIgnoreCase(String), TokenQueue.consumeWord(), TokenQueue.matchesAny(String...)

Functional Improvements

• Rebuilt the HTML pretty-printer, to simplify and consolidate the implementation, improve consistency, support custom
  Tags, and provide a cleaner path for ongoing improvements. The specific HTML produced by the pretty-printer may be
  different from previous versions. #​2286.
• Added the ability to define custom tags, and to modify properties of known tags, via the TagSet tag collection.
  Their properties can impact both the parse and how content is
  serialized (output as HTML or XML). #​2285.
• Element.cssSelector() will prefer to return shorter selectors by using ancestor IDs when available and unique. E.g.
  #id > div > p instead of html > body > div > div > p #​2283.
• Added Elements.deselect(int index), Elements.deselect(Object o), and Elements.deselectAll() methods to remove
  elements from the Elements list without removing them from the underlying DOM. Also added Elements.asList() method
  to get a modifiable list of elements without affecting the DOM. (Individual Elements remain linked to the
  DOM.) #​2100.
• Added support for sending a request body from an InputStream with
  Connection.requestBodyStream(InputStream stream). #​1122.
• The XML parser now supports scoped xmlns: prefix namespace declarations, and applies the correct namespace to Tags and
  Attributes. Also, added Tag#prefix(), Tag#localName(), Attribute#prefix(), Attribute#localName(), and
  Attribute#namespace() to retrieve these. #​2299.
• CSS identifiers are now escaped and unescaped correctly to the CSS spec. Element#cssSelector() will emit
  appropriately escaped selectors, and the QueryParser supports those. Added Selector.escapeCssIdentifier() and
  Selector.unescapeCssIdentifier(). #​2297, #​2305

Structure and Performance Improvements

• Refactored the CSS QueryParser into a clearer recursive descent
  parser. #​2310.
• CSS selectors with consecutive combinators (e.g. div >> p) will throw an explicit parse
  exception. #​2311.
• Performance: reduced the shallow size of an Element from 40 to 32 bytes, and the NodeList from 32 to 24.
  #​2307.
• Performance: reduced GC load of new StringBuilders when tokenizing input
  HTML. #​2304.
• Made Parser instances threadsafe, so that inadvertent use of the same instance across threads will not lead to
  errors. For actual concurrency, use Parser#newInstance() per
  thread. #​2314.

Bug Fixes

• Element names containing characters invalid in XML are now normalized to valid XML names when
  serializing. #​1496.
• When serializing to XML, characters that are invalid in XML 1.0 should be removed (not
  encoded). #​1743.
• When converting a Document to the W3C DOM in W3CDom, elements with an attribute in an undeclared namespace now
  get a declaration of xmlns:prefix="undefined". This allows subsequent serialization to XML via W3CDom.asString()
  to succeed. #​2087.
• The StreamParser could emit the final elements of a document twice, due to how onNodeCompleted was fired when closing out the stack. #​2295.
• When parsing with the XML parser and error tracking enabled, the trailing ? in <?xml version="1.0"?> would
  incorrectly emit an error. #​2298.
• Calling Element#cssSelector() on an element with combining characters in the class or ID now produces the correct output. #​1984.

v1.19.1

Changes

• Added support for http/2 requests in Jsoup.connect(), when running on Java 11+, via the Java HttpClient
  implementation. #​2257.
  • In this version of jsoup, the default is to make requests via the HttpUrlConnection implementation: use
    System.setProperty("jsoup.useHttpClient", "true"); to enable making requests via the HttpClient instead ,
    which will enable http/2 support, if available. This will become the default in a later version of jsoup, so now is
    a good time to validate it.
  • If you are repackaging the jsoup jar in your deployment (i.e. creating a shaded- or a fat-jar), make sure to specify
    that as a Multi-Release
    JAR.
  • If the HttpClient impl is not available in your JRE, requests will continue to be made via
    HttpURLConnection (in http/1.1 mode).
• Updated the minimum Android API Level validation from 10 to 21. As with previous jsoup versions, Android
  developers need to enable core library desugaring. The minimum Java version remains Java 8.
  #​2173
• Removed previously deprecated class: org.jsoup.UncheckedIOException (replace with java.io.UncheckedIOException);
  moved previously deprecated method Element Element#forEach(Consumer) to
  void Element#forEach(Consumer()). #​2246
• Deprecated the methods Document#updateMetaCharsetElement(boolean) and Document#updateMetaCharsetElement(), as the
  setting had no effect. When Document#charset(Charset) is called, the document's meta charset or XML encoding
  instruction is always set. #​2247

Improvements

• When cleaning HTML with a Safelist that preserves relative links, the isValid() method will now consider these
  links valid. Additionally, the enforced attribute rel=nofollow will only be added to external links when configured
  in the safelist. #​2245
• Added Element#selectStream(String query) and Element#selectStream(Evaluator) methods, that return a Stream of
  matching elements. Elements are evaluated and returned as they are found, and the stream can be
  terminated early. #​2092
• Element objects now implement Iterable, enabling them to be used in enhanced for loops.
• Added support for fragment parsing from a Reader via
  Parser#parseFragmentInput(Reader, Element, String). #​1177
• Reintroduced CLI executable examples, in jsoup-examples.jar. #​1702
• Optimized performance of selectors like #id .class (and other similar descendant queries) by around 4.6x, by better
  balancing the Ancestor evaluator's cost function in the query
  planner. #​2254
• Removed the legacy parsing rules for <isindex> tags, which would autovivify a form element with labels. This is no
  longer in the spec.
• Added Elements.selectFirst(String cssQuery) and Elements.expectFirst(String cssQuery), to select the first
  matching element from an Elements list. #​2263
• When parsing with the XML parser, XML Declarations and Processing Instructions are directly handled, vs bouncing
  through the HTML parser's bogus comment handler. Serialization for non-doctype declarations no longer end with a
  spurious !. #​2275
• When converting parsed HTML to XML or the W3C DOM, element names containing < are normalized to _ to ensure valid
  XML. For example, <foo<bar> becomes <foo_bar>, as XML does not allow < in element names, but HTML5
  does. #​2276
• Reimplemented the HTML5 Adoption Agency Algorithm to the current spec. This handles mis-nested formating / structural elements. #​2278

Bug Fixes

• If an element has an ; in an attribute name, it could not be converted to a W3C DOM element, and so subsequent XPath
  queries could miss that element. Now, the attribute name is more completely
  normalized. #​2244
• For backwards compatibility, reverted the internal attribute key for doctype names to
  "name". #​2241
• In Connection, skip cookies that have no name, rather than throwing a validation
  exception. #​2242
• When running on JDK 1.8, the error java.lang.NoSuchMethodError: java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer;
  could be thrown when calling Response#body() after parsing from a URL and the buffer size was
  exceeded. #​2250
• For backwards compatibility, allow null InputStream inputs to Jsoup.parse(InputStream stream, ...), by returning
  an empty Document. #​2252
• A template tag containing an li within an open li would be parsed incorrectly, as it was not recognized as a
  "special" tag (which have additional processing rules). Also, added the SVG and MathML namespace tags to the list of
  special tags. #​2258
• A template tag containing a button within an open button would be parsed incorrectly, as the "in button scope"
  check was not aware of the template element. Corrected other instances including MathML and SVG elements,
  also. #​2271
• An :nth-child selector with a negative digit-less step, such as :nth-child(-n+2), would be parsed incorrectly as a
  positive step, and so would not match as expected. #​1147
• Calling doc.charset(charset) on an empty XML document would throw an
  IndexOutOfBoundsException. #​2266
• Fixed a memory leak when reusing a nested StructuralEvaluator (e.g., a selector ancestor chain like A B C) by
  ensuring cache reset calls cascade to inner members. #​2277
• Concurrent calls to doc.clone().append(html) were not supported. When a document was cloned, its Parser was not cloned but was a shallow copy of the original parser. #​2281

v1.18.3

Bug Fixes

• When serializing to XML, attribute names containing -, ., or digits were incorrectly marked as invalid and
  removed. 2235

v1.18.2

Improvements

• Optimized the throughput and memory use throughout the input read and parse flows, with heap allocations and GC
  down between -6% and -89%, and throughput improved up to +143% for small inputs. Most inputs sizes will see
  throughput increases of ~ 20%. These performance improvements come through recycling the backing byte[] and char[]
  arrays used to read and parse the input. 2186
• Speed optimized html() and Entities.escape() when the input contains UTF characters in a supplementary plane, by
  around 49%. 2183
• The form associated elements returned by FormElement.elements() now reflect changes made to the DOM,
  subsequently to the original parse. 2140
• In the TreeBuilder, the onNodeInserted() and onNodeClosed() events are now also fired for the outermost /
  root Document node. This enables source position tracking on the Document node (which was previously unset). And
  it also enables the node traversor to see the outer Document node. 2182
• Selected Elements can now be position swapped inline using
  Elements#set(). 2212

Bug Fixes

• Element.cssSelector() would fail if the element's class contained a *
  character. 2169
• When tracking source ranges, a text node following an invalid self-closing element may be left
  untracked. 2175
• When a document has no doctype, or a doctype not named html, it should be parsed in Quirks
  Mode. 2197
• With a selector like div:has(span + a), the has() component was not working correctly, as the inner combining
  query caused the evaluator to match those against the outer's siblings, not
  children. 2187
• A selector query that included multiple :has() components in a nested :has() might incorrectly
  execute. 2131
• When cookie names in a response are duplicated, the simple view of cookies available via
  Connection.Response#cookies() will provide the last one set. Generally it is better to use
  the Jsoup.newSession method to maintain a cookie jar, as that
  applies appropriate path selection on cookies when making requests. 1831
• When parsing named HTML entities, base entities should resolve if they are a prefix of the input token (and not in an
  attribute). 2207
• Fixed incorrect tracking of source ranges for attributes merged from late-occurring elements that were implicitly
  created (html or body). 2204
• Follow the current HTML specification in the tokenizer to allow < as part of a tag name, instead of emitting it as a
  character node. 2230
• Similarly, allow a < as the start of an attribute name, vs creating a new element. The previous behavior was
  intended to parse closer to what we anticipated the author's intent to be, but that does not align to the spec or to
  how browsers behave. 1483
