[libxml++] xpath with namespaces

[Curtis Spencer <thorin gmail com>]

Hi, 

I saw this post sometime in July, and now I am running into the same
problem.  Does anyone have an answer for this?

 Hello,
 
 I"m trying to use XPaths on documents which use namespaces (e.g. 
 libxml++-2.6.1/examples/sax_exception/example.xml). My code looks like this:
 
 xmlpp::DomParser dp;
 dp.parse_file("example.xml");
 xmlpp::Document* doc = dp.get_document();
 xmlpp::Element* root = doc->get_root_node();
 xmlpp::NodeSet set = root->find("//gjob:Jobs");
 
 If I use "//gjob:Jobs" i get "XPath error : Undefined namespace prefix", 
 and "//Jobs" just returns an empty set.
 I assume I have to register the namespace first, but I couldn"t find 
 anything about this in the documentation.
 
 thanks in advance for your help.

Thanks,

Curtis
