[jdom-interest] variable evaluation in XPATH expression

[Alastair Rodgers]

It's on org.jaxen.XPath - do you have jaxen-full.jar in your classpath? I'm using JDOM beta 9 and Jaxen 1.0 FCS (from http://jaxen.org/).

Oops! Formatting got a bit screwed up there. Here it is again:

XPath xpath = new JDOMXPath("/*/*/subcategory[@mappedname=$map]");
SimpleVariableContext vars = new SimpleVariableContext(); 
vars.setVariableValue(null, "map", "europe"); 
xpath.setVariableContext(vars); 
Element result = (Element)xpath.selectSingleNode(doc);
