Parsing XML with JAXP

[Rick Crawford]

Hello all. Could someone kindly post some code to show me how to parse the following example XML data (read in from a string?)
<?xml version="1.0" ?>
<FORMDATA>
<BILLING>
<INVOICENO>1111111</INVOICENO>
<CUSTOMERNO>ABC123</CUSTOMERNO>
</BILLING>
</FORMDATA>
I'm using the JAXP parser. The document seems to be parsing okay, as I can System.out.println doc.getDocumentElement() and see the entire XML stream.
Here's the code I've got so far, which isn't much:

    public void dumpVars(String s) throws Exception {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        ByteArrayInputStream bais = new ByteArrayInputStream(s.getBytes());
        Document doc = builder.parse(bais);
// what to do now?
}

I'm after the value of the INVOICENO and CUSTOMERNO. Is there some sort of way to access the value of these elements by XML tag names?
Thanks in advance for the help,
Rick <><

Hei
after parsing you can take the values by getting to the node
you can take this by using the method
NodeList nl = Document.getElementsByTagName("INVOICENO");
as shown above this gives all the elements with the said name.
Node invoice= nl.item(0); \\this gives you the code the value '0' denotes the first element
Node value = invoice.getFirstChild(); \\this gives the text node from where you can take the value
String s = value.getNodeValue();
Hope this helps
Cheers
