Re: [xml-dev] XPath search problem


Marshall, Steven (SKM) a écrit :

In your XML document, there is a default namespace URI which is applied 
to all unprefixed elements (in the scope). With XPath, unprefixed 
elements have no namespace URI, so you have to bound them to the 
expected namespace URI by using the prefix of your choice ; you should 
have something like this :

nsm.declare( "GMX", "http://www.isotc211.org/2005/gmx"; )
Code']/GMX:codeEntry", nsm)

The different behaviour you noticed is certainly due to the tool that 
likely uses XPath 2 (unlike XPath 1 you can set a default namespace URI 
that applies to unprefixed elements with XPath 2) whereas your processor 
uses XPath 1.

The other workaround would be to configure your XPath processor to be 
compliant to XPath 2
