Element findElement(Document doc, String elementNS, String elementName, String attrName, String attrValue)
find Element

return findElement(doc.getDocumentElement(), elementNS, elementName, attrName, attrValue);

Element findElement(Document doc, String tagName, Properties props)
Find an element

Element elmt = null;
NodeList nlist = doc.getElementsByTagName(tagName);
for (int i = 0; i < nlist.getLength() && elmt == null; i++) {
 Node node = nlist.item(i);
 if (node instanceof Element) {
 Element temp = (Element) node;
 boolean matches = true;
 for (Enumeration en = props.keys(); en.hasMoreElements() && matches;) {
...

Element findElement(String name, Document doc)
Finds the first (breadth first) DOM element with the specified name.

return findElement(name, null, null, doc);

Element findElementAndSetElseCreateAndSet(Document document, Element parent, String child, boolean value)
find Element And Set Else Create And Set

return findElementAndSetElseCreateAndSet(document, parent, child, "" + value);

Element findElementElseCreateAndSet(Document document, Element parent, String child, boolean value)
find Element Else Create And Set

return findElementElseCreateAndSet(document, parent, child, value + "");

Vector findElementList(String name, String attrName, String attrValue, Document doc)
Gets a list of DOM elements with the specified name that have an attribute with the given name and value.

if (name == null)
 return null;
Vector v = new Vector();
NodeList list = doc.getElementsByTagName(name);
int size = list.getLength();
for (int i = 0; i < size; i++) {
 Node node = list.item(i);
 if (!(node instanceof Element))
...

Element findElementOrContainer(Document document, Element parent, String element)
find Element Or Container

NodeList nl = parent.getElementsByTagName(element);
if (nl.getLength() == 0) {
 return null;
return (Element) nl.item(0);

Element getElement(Document doc, QName elementQName)

Get an element from the document given its QName

First an attempt to get the element based on its namespace is made, failing which an element with the localpart ignoring any namespace is returned.

NodeList nl = doc.getElementsByTagNameNS(elementQName.getNamespaceURI(), elementQName.getLocalPart());
if (nl.getLength() == 0) {
 nl = doc.getElementsByTagNameNS("*", elementQName.getLocalPart());
 if (nl.getLength() == 0)
 nl = doc.getElementsByTagName(elementQName.getPrefix() + ":" + elementQName.getLocalPart());
 if (nl.getLength() == 0)
 return null;
return (Element) nl.item(0);

String getElement(Document doc, String path)
get Element

return xpath.compile(path).evaluate(doc);

Element getElement(Document pDocument, String psTagName, int index)
returns a XML element.

NodeList rows = pDocument.getDocumentElement().getElementsByTagName(psTagName);
return (Element) rows.item(index);
