Get child Node of another Node, given node name

Question

I have an XML like this:

  
    1
    Declaration of Human Rights         


        

Answer 1

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);
}
