ElementfindElement(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;) {
...
ElementfindElement(String name, Document doc)
Finds the first (breadth first) DOM element with the specified name. 
return findElement(name, null, null, doc);
ElementfindElementAndSetElseCreateAndSet(Document document, Element parent, String child, boolean value)
find Element And Set Else Create And Set 
return findElementAndSetElseCreateAndSet(document, parent, child, "" + value);

VectorfindElementList(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();

ElementfindElementOrContainer(Document document, Element parent, String element)
find Element Or Container 
NodeList nl = parent.getElementsByTagName(element);
if (nl.getLength() == 0) {

return (Element) nl.item(0);
ElementgetElement(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);
StringgetElement(Document doc, String path)
get Element 
return xpath.compile(path).evaluate(doc);
ElementgetElement(Document pDocument, String psTagName, int index)
returns a XML element. 
NodeList rows = pDocument.getDocumentElement().getElementsByTagName(psTagName);
return (Element) rows.item(index);
