Subject How to use XPathAPI.selectNodeIternator when namespace is used?
Date Wed, 09 Jan 2002 15:56:46 GMT

I did post this question to xalan-j-user but I got no response.

Could someone tell me what changes to ApplyXPath.java example program
(version 2.2 D14) is required when namespace is used?

For example, given an XML named test.xml: 
<?xml version="1.0" encoding="UTF-8"?> 

This test.xml works fine with the ApplyXPath.java sample program.  We could
run it with the command: 
java ApplyXPath test.xml /root 
and will get everything as <output><root> ... </root></output> 

However, if the namespace is used and declared, for example, as: 
<?xml version="1.0" encoding="UTF-8"?> 
<root xmlns=" <http://www.xxx.com/ns>" 
xmlns:xsi=" <http://www.w3.org/2001/XMLSchema-instance>" 
xsi:schemaLocation=" <http://www.xxx.com/ns> test.xsd"> 

In this case the ApplyXPath will not be able to extract the nodeIternator
'root' and it therefore returns null.  The output of the ApplyXPath will
then be

I understand that if I modify the ApplyXPath program and change the line
setNamespaceAware to
then the XPathApi.selectNodeIternator(doc, xpath) will then return a correct

What should we do if we do need the
DocumentBuilderFactory.setNamespaceAware(true)?  What changes are required
to make the ApplyXPath.java?
