Using an XPath _expression_, how can I get a XalanNode that can be updated? It seems like the resulting nodelist has nodes which are all read-only; i.e., setValue(), setNodeValue(), et al, throw XalanDOMException(NO_MODIFICATION_ALLOWED_ERR).
I'm trying to convert a sizable (MS-parser-based) app that uses XPath a *lot* to get a "live" node that is updated. My feeble brain is not seeing how to do this using Xerces/Xalan.
