[xml] Question regarding XPath

["Ethan Metsger" <emetsger obj-sys com>]

Hi, all.

I'm pretty new to libxml2, having just been assigned to integrate its  
source with our XML databinding tool.  We make a call to  
xmlXPathEvalExpression as follows:

   res = xmlXPathEvalExpression (BAD_CAST nodeName, xpctxt);

Our namespaces are registered using xmlXPathRegisterNs.  We use the  
following XPath query:

   "//xs:element | //xs:simpleType"

This returns many nodes when we link against libxml2-2.6.9, but zero with  
libxml2-2.6.27.  Obviously this is a rather significant jump, but it seems  
to be as though the behavior of xmlXPathEvalExpression has changed between  
these point releases.  In reading over the changelogs, I didn't find  
anything terribly relevant (as far as I can tell) to the situation, and  
the only advice I was able to dig up was to make sure that the namespaces  
were indeed qualified.

Does anyone have any advice and/or resources that might prove helpful?


Best,

Ethan
