Comment addComment(Node node, String comment)
add Comment

Document doc = null;
if (node.getNodeType() == Node.DOCUMENT_NODE) {
 doc = (Document) node;
} else {
 doc = node.getOwnerDocument();
Comment e = doc.createComment(comment);
node.appendChild(e);
...

void addDescendants(Node node, List descendants)
Adds descendant elements of a node to a list.

NodeList children = node.getChildNodes();
int numChildren = children.getLength();
for (int i = 0; i < numChildren; i++) {
 Node child = children.item(i);
 if (child.getNodeType() == Node.ELEMENT_NODE) {
 descendants.add(child);
 addDescendants(child, descendants);

void addImageSource(Node test, List holder)
add Image Source

if (test.getNodeType() != Node.ELEMENT_NODE)
 return;
Element RealTest = (Element) test;
Node SourceNode = RealTest.getAttributeNode("SRC");
if (SourceNode == null)
 return;
String text = SourceNode.getNodeValue();
if (text == null || text.length() == 0)
...

void addNodeValue(Node node, String name, boolean value)
add Node Value

addNodeValue(node, name, value ? "true" : "false");

Node addValue(Node node, String value)
Add a value to the specified node

final Node newNode;
if (node instanceof Document)
 newNode = ((Document) node).createTextNode(value);
else
 newNode = node.getOwnerDocument().createTextNode(value);
if (newNode != null)
 node.appendChild(newNode);
return newNode;
...

void appendChild(Node parent, Node child)
Checks if child element has same owner document before appending to the parent, and imports it to the parent's document if necessary.

Document ownerDoc = getOwnerDocument(parent);
if (child.getOwnerDocument() != ownerDoc) {
 parent.appendChild(ownerDoc.importNode(child, true));
} else {
 parent.appendChild(child);

Node appendForeignChild(Node node, Node foreignChild)
append Foreign Child

return node.appendChild(node.getOwnerDocument().importNode(foreignChild, true));

boolean canAppend(Node node, Node parentNode)
Checks if the node can be appended on the given parent node

if (node == null || parentNode == null || node == parentNode || isAncestorOf(node, parentNode)) {
 return false;
return true;
