RE: Accessing to a specific child Element

Hi i wrote a utility function like this, to get the specified node value...

public static final String getFirstNodeValue(Node p, String s) {
        Node e = getFirstNode(p, s);
        Node c = (e != null) ? e.getFirstChild() : null;
        return (c != null) ? c.getNodeValue() : "";
        }


public static final Node getFirstNode(Node p, String s) {
        NodeList list = p.getChildNodes();
        if (list != null) for (int i=0; i<list.getLength(); i++) {
                Node node = list.item(i);
                if (node.getNodeName().compareTo(s) == 0)
                    return node;
                }
        return null;
        }


Hope this helps!!!!!

Subject: Accessing to a specific child Element


Hi all.

    Single question. I'd like to access to a specific child Element. Knowing
that you have one and only one Element with the desired Tag Name, how can I
get 'that' Element?.
    I know that I can use getElementsByTagName(String), but ,as you know it
returns a NodeList, so I have to declare a NodeList.
Any shorter way to do it?

Thanks in advance.
