XPath Not Working (Namespace ?)

Question

I am not receiving any errors, but similair XPath in XMLSpy works...
I have an XML document:
<Results>
<acc:Account xmlns:account="http://test/account" id="1">
<acc:Name>Account Name 1</acc:Name>
</acc:Account>
<acc:Account xmlns:account="http://test/account" id="2">
<acc:Name>Account Name 2</acc:Name>
</acc:Account>
</Results>
When I use: "//Results" I get a a Node back
When I use: //Results/acc:Account[@id=1], I get no results back and no errors
To avoid namespace problems I used a StaticNamespaceResolver...
My code:
HashMap prefixes = new HashMap(1);
String namespace = "http://test/account";
prefixes.put("acc", namespace);
try {
     XObject obj = XPathAPI.eval(RootNode, queryStr, new StaticPrefixResolverImpl(prefixes));
NodeList nl = obj.nodelist();
System.out.println("NodeList Length: " + nl.getLength());
} catch (Exception ee) {
System.out.println(ee);
Thanks!

Seems to me your problem is that you can't decide what prefix to use...
Is it 'acc' or 'account' ?
In your sample document, try:
<Results>
<acc:Account xmlns:acc="http://test/account" id="1">
<acc:Name>Account Name 1</acc:Name>
</acc:Account>
<acc:Account xmlns:acc="http://test/account" id="2">
<acc:Name>Account Name 2</acc:Name>
</acc:Account>
</Results>And see what the difference is...
Also, the prefix you use in your XPath expression does not have to be the same as the one used in the document. They are linked via the URI and a NamespaceContext. It's quite likely you'll need to implement a NamespaceContext (depending on what XPath API you are using).
