Document clone(Document doc)
Clone a document so it can be safely modified on a per-request basis.

Document d;
try {
 d = newBuilder().newDocument();
} catch (ParserConfigurationException e) {
 throw new IOException("Cannot clone document");
Node n = d.importNode(doc.getDocumentElement(), true);
d.appendChild(n);
...

Document clone(Document inDoc)
Clone a Document.

Document rtnVal = (Document) inDoc.cloneNode(true);
return (rtnVal);

void cloneAndAppend(Document document, Node node)
clone And Append

node = node.cloneNode(true);
document.adoptNode(node);
document.appendChild(node);

Document cloneDocument(Document document)
clone Document

if (document == null)
 return null;
Document result = newDocument();
try {
 identityTransformer.transform(new DOMSource(document), new DOMResult(result));
} catch (TransformerException e) {
 e.printStackTrace();
return result;

Document cloneDocument(final Document doc)
Clones a document object.

final Node rootNode = doc.getDocumentElement();
final TransformerFactory tfactory = TransformerFactory.newInstance();
final Transformer tx = tfactory.newTransformer();
final DOMSource source = new DOMSource(doc);
final DOMResult result = new DOMResult();
tx.transform(source, result);
final Document copy = (Document) result.getNode();
copy.removeChild(copy.getDocumentElement());
...

Document cloneDocument(final Document doc)
Creates an exact clone of a Document.

if (doc == null) {
 throw new IllegalArgumentException("The document source cannot be null.");
return (Document) doc.cloneNode(true);

Document cloneDOM(final Document src)
Create a clone of a DOM object

final Transformer transformer = sTransformerFactory.newTransformer();
final DOMSource srcDom = new DOMSource(src);
final DOMResult resultDom = new DOMResult();
transformer.transform(srcDom, resultDom);
return (Document) resultDom.getNode();

Node cloneDOM(Node node, Document document)
Recursively copy the DOM tree using the specified document as the root document factory.

Node clone = null;
if (node != null) {
 switch (node.getNodeType()) {
 case Node.ELEMENT_NODE:
 clone = document.createElement(node.getNodeName());
 NamedNodeMap attrs = node.getAttributes();
 int nattrs = (attrs == null ? 0 : attrs.getLength());
 for (int a = 0; a < nattrs; a++) {
...

Node cloneNode(Document d, Node n)
clone Node

Node r = null;
switch (n.getNodeType()) {
case Node.TEXT_NODE:
 r = d.createTextNode(((Text) n).getData());
 break;
case Node.CDATA_SECTION_NODE:
 r = d.createCDATASection(((CDATASection) n).getData());
 break;
...

Node cloneNode(Document document, Node node, boolean deep)
clone Node

if (document == null || node == null) {
 return null;
int type = node.getNodeType();
if (node.getOwnerDocument() == document) {
 return node.cloneNode(deep);
Node clone;
