[jdom-interest] [Q]Problem at the search JDOM with JaxenXPath

[Laurent Bihanic]

Hi,

The XPath expressions used with Jaxen and Apache XPath are different 
(M7:description is declared as an attribute with Jaxen (/@M7:description) and 
as a child element with Apache (/M7:description)). Couldn't that be the source 
of the problem?
