Ok,
You must put always namespaceAware(true), for fixing your xpath
problems is recommended to do something like that:
Element nscontext = XMLUtils.createDSctx(doc, "ds",
Constants.SignatureSpecNS);
//retrieve the signature Element from the document
Element sigElement = (Element) XPathAPI.selectSingleNode(doc,
"//ds:Signature[1]", nscontext);
Please note how it creates a node and see how it binds to a URI, and
then how it does the search.
I think this will fix your problems.
This example was taken from the samples in the xml-sec, but it is also
described in the xalan faq.
Regards,
Raul
