How to get a node value of an XML element?

[rsenth99]

Hi all

I am trying to parse an xml file and get the node value.

XML Code:
<assign name="Transform_1">
<bpelx:annotation>
<bpelx: pattern>transformation</bpelx: pattern>
</bpelx:annotation>
</assign>

I need to get the node value of the element 'bpelx: pattern'.

Java Code:
if (list1.getLength() != 0) {
for (int k = 0; k < list1.getLength(); k++) {
Node node = list1.item(k);
System.out.println("Node Name : "+node.getNodeName());
NamedNodeMap nodeMap = node.getAttributes();
System.out.println("Node Value : "+node.getNodeValue());

But I am getting the node value as 'NULL'. Please let me know your valuable suggestions to solve this issue.

What is list1?
That code really doesn't help us in determine how you're trying to get hold of the node in question.

[rsenth99]

'list1' is an object that contains all the elements in the XML file.

[Tolls]

OK, clearly you missed the not-so-subtle request for more code...
So list1 is a NodeList? Gained from a getElementsByTagName (or similar)?

Anyway...

Look at the api and see if you can guess why nodeValue is always null. Remember that your NodeList is almost certainly all elements.

[rsenth99]

NodeList list1 = doc.getElementsByTagName("*");

Why are you selecting every node when you're only interested in the <pattern> ones?
And you'll want to cast the Nodes in that list to Elements so you can actually use them.

Use another parser? :p
I use stax, its faster and easier to understand
what does it returns when calling method getLocalName()?

[Tolls]

The parser really doesn't matter. If they're not using the one they have properly then there's really no reason to expect them to use a different one properly.

getNodeValue() returns null for all Element (see javadoc of org.w3c.dom.Node), so use getTextContent() instead.

Is there an echo in here?
