157933 - Namespaces are not recognized by XPath

Status: RESOLVED WONTFIX

(Core :: XSLT, defect)

Description

[Azamat Sagatov]

I'm trying to use Xpath search engine for XML documents containing namespaces.
And it appears that it's impossible to query for an element with namespace prefix. 
I'm trying to run the following script:

function bodyOnLoad()
{
	sXML_ns = 
	'<?xml version="1.0" encoding="UTF-8"?><saw:wasq
xmlns:saw="http://kkk"><petyk><saw:bob/></petyk></saw:wasq>';
	
	docXML_ns=(new DOMParser()).parseFromString(sXML_ns, "text/xml");	        
    	rslv = docXML_ns.createNSResolver(docXML_ns.documentElement);
//test N1 - try to resolve NS prefix
	alert("saw URI: " + rslv.lookupNamespaceURI('saw'));
	
//test N2 - selectSingleNode; no namespaces 
	var tPT = selectSingleNode(docXML_ns.documentElement,"petyk",rslv);
	alert("tPT == null: " + (tPT == null));
	if (tPT != null)
	   alert("eval = " + (new XMLSerializer()).serializeToString(tPT));

//test N2 -  selectSingleNode; namespaces 
	tPT = selectSingleNode(docXML_ns.documentElement,"petyk/saw:bob",rslv);
	alert("tPT == null: " + (tPT == null));
	if (tPT != null)
	   alert("eval = " + (new XMLSerializer()).serializeToString(tPT));
}

function selectSingleNode(elem,expr,rslv)
{
	return  elem.ownerDocument.evaluate(expr, elem, rslv, 0, null).iterateNext();
}

Results:
Test 1 works - namespace prefix is resolved correctly using NS resolver.
Test 2 works - search for an element without namespace prefix returns correct
result.
Test 3 fails. Instead of an expected element it returns null.

Version of Mozilla browser I'm using (from Help/About screen) is:

Mozilla 1.0
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.0.0) Gecko/20020530

Please help. We are trying to port existing IE application to Mozilla and this
bug is really critical for us.

Thanks,
Azamat

This is a known problem for the 1.0 release. Try a tipbuild (or it might even
work with an 1.1alpha)

Not a blocker.

Azamat: could you please try this with a more recent build. It should be fixed
in the 1.1beta release.

Marking as worksforme. If this still doesn't work for you with a recent nightly
then please reopen this bug
