Get child Node of another Node, given node name

If the Node is not just any node, but actually an Element (it could also be e.g. an attribute or a text node), you can cast it to Element and use getElementsByTagName.

Check if the Node is a Dom Element, cast, and call getElementsByTagName()

Node doc = docs.item(i);if(doc instanceof Element) {    Element docElement = (Element)doc;    ...    cell = doc.getElementsByTagName("aoo").item(0);}

You should read it recursively, some time ago I had the same question and solve with this code:

public void proccessMenuNodeList(NodeList nl, JMenuBar menubar) {    for (int i = 0; i < nl.getLength(); i++) {        proccessMenuNode(nl.item(i), menubar);    }}public void proccessMenuNode(Node n, Container parent) {    if(!n.getNodeName().equals("menu"))        return;    Element element = (Element) n;    String type = element.getAttribute("type");    String name = element.getAttribute("name");    if (type.equals("menu")) {        NodeList nl = element.getChildNodes();        JMenu menu = new JMenu(name);        for (int i = 0; i < nl.getLength(); i++)            proccessMenuNode(nl.item(i), menu);        parent.add(menu);    } else if (type.equals("item")) {        JMenuItem item = new JMenuItem(name);        parent.add(item);    }}

Probably you can adapt it for your case.
