At the moment, there is no XPath support for the gb.xml component.

However, if you want to select specific nodes, you have several methods
at your disposal :

* The XmlElement.GetChildrenByTagName()[0] can be used to search elements
   with specific tag names, but it also supports LIKE[1] patterns. It can
   also receive a depth parameter if you want to restrict your search;
* The XmlElement.GetChildrenByAttributeValue()[2] works with similar  
options;
* The gb.xml.html sub-component adds a XmlElement.GetChildrenByFilter()[3]  
method,
   to which you can pass a CSS filter. Not all CSS expressions are  
supported though
   (see the MatchFilter()[4] help).

Hope that helps,
