Java Utililty Methods XML Attribute from Node

void generateIds(Node root, String attrName)
adds an attribute with random value to all elements, that do not have an attribute with the specified name.

if (root.getNodeType() == Node.ELEMENT_NODE) {
 Element e = (Element) root;
 String id = e.getAttribute(attrName);
 if (id == null || id.length() == 0)
 e.setAttribute(attrName, randomId());
NodeList list = root.getChildNodes();
int N = list.getLength();
...

Vector getALLAttribute(final Node iNode)
get ALL Attribute

Vector<Attr> result = new Vector<Attr>();

 int numAttr = attrList.getLength();
 Attr currentAttrNode = null;
 for (int k = 0; k < numAttr; k++) {
 currentAttrNode = (Attr) attrList.item(k);
 result.add(currentAttrNode);
