Answer 1

This is java code to get the child node with given attribute name and value. Is this what you are looking for

    public static Element getNodeWithAttribute(Node root, String attrName, String attrValue)
{
    NodeList nl = root.getChildNodes();
    for (int i = 0; i < nl.getLength(); i++) {
        Node n = nl.item(i);
        if (n instanceof Element) {
            Element el = (Element) n;
            if (el.getAttribute(attrName).equals(attrValue)) {
                return el;
            }else{
       el =  getNodeWithAttribute(n, attrName, attrValue); //search recursively
       if(el != null){
        return el;
       }
    }
        }
    }
    return null;
}
