Late night DOM question

[Brett McLaughlin <br...@earthlink.net>]

I must be getting stupid as the night wears on... can someone point me in the direction in what error I am making?

For the following XML document:

<?xml version="1.0"?>

<JavaXML:xmlrpc-config xmlns:JavaXML="http://myUrl.com">
  <JavaXML:hostname>localhost</JavaXML:hostname>
  <JavaXML:port type="unprotected">85</JavaXML:port>
</JavaXML:xmlrpc-config>

and this code snippet:

try {
    DOMParser parser = new (org.apache.xerces.parsers.)DOMParser();
    parser.parse(uri);    // Parse supplied document
    Document doc = parser.getDocument();

    NodeList nodes = doc.getElementsByTagName("JavaXML:hostname");
    if (nodes.getLength() > 0) {
      hostname = nodes.item(0).getNodeValue();
    }

    nodes = doc.getElementsByTagName("JavaXML:port");
    if (nodes.getLength() > 0) {
      portNumber = (Integer.parseInt(nodes.item(0).getNodeValue());
    }
} // exception handling

this never pulls any data out for me.  However,

NodeList nodes = doc.getElementsByTagName("*");
and then printing each node's getNodeName() result gives me:

JavaXML:xmlrpc-config
JavaXML:hostname
JavaXML:port

What am I missing?

Thanks,
Brett

Hi Brett,

I believe you are missing:

Element root = doc.getDocumentElement();

-then- call:

NodeList nodes = root.getElementsByTagName("JavaXML:hostname");
if (nodes.getLength() > 0) {
   hostname = nodes.item(0).getNodeValue();
}

nodes = root.getElementsByTagName("JavaXML:port");
   if (nodes.getLength() > 0) {
   portNumber = (Integer.parseInt(nodes.item(0).getNodeValue());
}

Chris

and then from there, call
