XPP3 Namespace Use   Message List  
Reply | Forward Message #304 of 308 |
Hi all,

I am using XPP3 to parse a document containing a custom namespace
and use an XPath predicate to pull out an element, but XPP3 does not
find the element! Without the namespace this example works fine, add
the namespace and it returns nothing. Have I failed to use XML
namespaces/XPP3 correctly? If so, could someone please point out how?

Thanks!
EG

The XML is like:
<ns1:A xmlns:ns1="http://some.url.org">
<ns1:B>
<ns1:C xyz="test"/>
</ns1:B>
</ns1:A>

The code I try to use looks like, and returns an empty ArrayList:
Xb1XPath predicateObj = new Xb1XPath("/ns1:A/ns1:B");

Object retObj = predicateObj.evaluate(docObj);

if (retObj != null) {
System.out.println(retObj.getClass().getName());

if (retObj instanceof ArrayList) {
System.out.println(((ArrayList) retObj).size());
}
} else
System.out.println("null");

Alek, Thanks for the quick reply! I believe that XPP3 is set to be namespace aware, as the factory method I call to give me an XmlInfosetBuilder object sets...
