Element.getElementByTagName() does not return all nodes

           Summary: Element.getElementByTagName() does not return all nodes
           Product: Xerces-J
           Version: 1.4.4
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: DOM
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


I've written a very simple test that parses a big SVG document as a DOM.
I then asks all "path" elements from the root element using 
getElementByTagName("path"). On small documents (e.g. containing 621 "path" 
elements, it works fine). On bigger documents (e.g. 1303 occurences of "path"), 
I only get 709 of them).

I was able to reproduce this bug with the following versions of Xerces-J 1.3.1, 
1.4.0, 1.4.4 (I haven't tried others).
using Sun's JVM, both versions 1.3.1_01 and 1.4.0beta3 (b84) 



I can provide you with the SVG document on which to run the test if you want it 
(it's about 600 Kb).

Here's the source code for my test.

This is huge! Hope you can solve it.
