[jdom-interest] Using XPath in Multi-Threaded Env

[Rajan Gupta]

All,
Is it possible to reuse an instance of XPath across multiple threads of
execution using different instances of DOM Documents in each thread?

I was looking at the code in JaxenPath.java & noticed that context is
stored as an attribute of the class, while not being really used anywhere
except in translateNamespacePrefixToUri() method. Following is a code
snippet.

public List selectNodes(Object context) throws JDOMException {
      try {
         currentContext = context;

         return xPath.selectNodes(context);
      }
      catch (JaxenException ex1) {
         throw new JDOMException("XPath error while evaluating \"" +
                        xPath.toString() + "\": " + ex1.getMessage(),
ex1);
      }
      finally {
         currentContext = null;
      }
   }

Thanks in advance,
Rajan
