Read datas from a xml node

Question

Hi,
I would read datas from a xml file, in example:
if the xml file is:
<FUNCTION>
<PARAM NAME="x"> 15 </PARAM>
<PARAM NAME="y"> 20 </PARAM>
</FUNCTION>
My program read the value between the xml tags (that is "15" and "20"), but I would read the value "x" and "y", how can I do?
My program is:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder =
factory.newDocumentBuilder();
Document document = builder.parse("xmlFile");
NodeList nl= document.getElementsByTagName("*");
for (int i=0; i<nl.getLength(); i++)
Node n=nl.item(i);
Node lc=n.getChild(...);
System.out.println(lc.getNodeValue());
Please help me

You want to get attribute nodes, which are technically not children of the node they appear in. The following method of Node looks helpful:
NamedNodeMap getAttributes()
A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.
