Reusing XPathContext for given Node to avoid time-consuming const ruction

[Niranjan Kundapur]

Hello,


I am processing around 10-15 compiled XPath objects on a single Node using
the method below. I notice that the empty constructor, new XPathContext(),
takes a significant amount of time. Is it possible to reuse the XPathContext
object for a _given_ Node so that it need not be constructed each time an
XPath needs to be executed on it? How is this implemented?  I am using
XalanD13 and jdk1.3.

    public NodeList processXPath(XPath xp, Node target) 
    throws javax.xml.transform.TransformerException
    {
        XPathContext context = new XPathContext(); //construct XPathContext
        XObject list = xp.execute(context, target, prefixResolver);
          return list.nodelist();
    }

Thank you in advance,
Niranjan
