Method

DocumentcopyDomDocument(Document originalDomDoc)
copy Dom Document 
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Node originalRoot = originalDomDoc.getDocumentElement();
Document copiedDocument = db.newDocument();
Node copiedRoot = copiedDocument.importNode(originalRoot, true);
copiedDocument.appendChild(copiedRoot);
return copiedDocument;
ElementcopyElement(Element orig, Document newOwner, Set blankTextNodes)
Makes a copy of the tree rooted at orig, considering only types Element and Attr. 
String tagName = orig.getTagName();
Element e = newOwner.createElement(tagName);
NamedNodeMap atts = orig.getAttributes();
for (int i = 0, len = atts.getLength(); i < len; ++i) {
    Attr origAttr = (Attr) atts.item(i);
    Attr newAttr = newOwner.createAttribute(origAttr.getName());
    newAttr.setValue(origAttr.getValue());
    e.setAttributeNode(newAttr);
...
NodecopyNode(Document new_doc, Node node)
copy Node 
Node new_node;
switch (node.getNodeType()) {
case Node.ELEMENT_NODE:
    new_node = new_doc.createElementNS(node.getNamespaceURI(), node.getNodeName());
    copyChildren(new_doc, node, new_node);
    return new_node;
case Node.TEXT_NODE:
    new_node = new_doc.createTextNode(((Text) node).getData());
...
NodecopyNode(final Document newDoc, final Node node)
copy Node 
final Node newNode;
switch (node.getNodeType()) {
case Node.ELEMENT_NODE:
    newNode = newDoc.createElementNS(node.getNamespaceURI(), node.getNodeName());
    final NamedNodeMap attributes = node.getAttributes();
    for (int i = 0; i < attributes.getLength(); i++) {
        final Attr attr = (Attr) attributes.item(i);
        final Attr newAttr = newDoc.createAttributeNS(attr.getNamespaceURI(), attr.getNodeName());
...
DocumentdeepCloneDocument(Document doc, DOMImplementation impl)
Deep clones a document using the given DOM implementation. 
Element root = doc.getDocumentElement();
Document result = impl.createDocument(root.getNamespaceURI(), root.getNodeName(), null);
Element rroot = result.getDocumentElement();
boolean before = true;
for (Node n = doc.getFirstChild(); n != null; n = n.getNextSibling()) {
    if (n == root) {
        before = false;
        if (root.hasAttributes()) {
...

    NodeList nl = (NodeList) expr.evaluate(ttml, XPathConstants.NODESET);
    for (int i = 0; i < nl.getLength(); i++) {
