  • Parsing a Namespace node with JDK 5.0

    I'm getting an unexplanatory XPathExpressionException when I evaluate the following xpath

    /xhtml:html/xhtml:body//xhtml:div[@class='reviewlist']

    after setting a namespace context

    NamespaceContextImpl nsctx = new NamespaceContextImpl();
    nsctx.setNamespaceURI("xml", "http://www.w3.org/XML/1998/namespace");
    nsctx.setNamespaceURI("xhtml", "http://www.w3.org/1999/xhtml");
    xpath.setNamespaceContext(nsctx);

    The source XML document is an XHTML web page with its root element being declared as belonging to http://www.w3.org/1999/xhtml namespace:

    <?xml version="1.0" encoding="ISO-8859-1"?>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">

    I can't see anything wrong with the xpath expression, nor can I find any documentation explaining why an XPathExpressionException would be thrown in this case.

    Could you tell any possisble causes for the exception being thrown?

    Thanks.
