validation and xpath problem

[buzzonus <bu...@yahoo.com>]

Hi,
I am using xerces 1.3.0 and am running into a problem where the XPathAPI.selectNodeList does
not return the expected nodes when I parse an xml file with ""http://xml.org/sax/features/validation" feature turned on. It works fine when this feature is disabled, i.e. set to false.Is this a know bug or I a missing something ?
Because if this problem, I now have to parse the file twice to get it into a dom..first with validation turned on and then with validation turned off (in the case when validation is a success)..this impact the the overall response time in my application. 
here is what my test code look like :
....
DOMParser parser = new DOMParser();
    parser.setFeature( "http://xml.org/sax/features/namespaces",
                                    true);
    parser.setFeature( "http://xml.org/sax/features/validation", 
                                   validation);
     parser.setFeature( "http://apache.org/xml/features/validation/schema",
                                        true );
     parser.parse(pData2);
    doc = parser.getDocument();   
    if (doc != null)
     {
      Element elm = doc.getDocumentElement();
      if (el != null)
      {
        System.out.println("docs root element tag name ="+elm.getTagName());
       try
       {
         NodeList nodes = XPathAPI.selectNodeList(doc,
          new String("descendant::tiger"));
         if (nodes == null)
           {
           System.out.println("did not find our tiger element");
         }
         else
           System.out.println("found "+nodes.getLength()+" tiger elements");
      }
.....

Here is the output for my sample xml:
1)with validation set to true:
docs root element tag name =abc
found 2 tiger elements

2)with validation set to false:
docs root element tag name =abc
found 0 tiger elements

any feedback would be appreciated.

thanks.

Hi,

first, you should ask this to the Xalan Mailing List, because XPathAPI is a 
Xalan object. From my point of view, XPathAPI has some problems (see 
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=1425 )

Best regards,

Christian
