-------------------------------------------------------------
And no I could not find a solution with the XPath API to let it be aware of the
default namesapce. There seems to be no good hooks for such kind.
Even if I added what may be a default namespace to the NamespaceContext the
xpath would still fail. The only solution I could get working is to use
namespace prefixes in the xpath expressions.
And the XPathExpression does not offer any callbacks or hooks to influence the
compiling. And I bet doing a string based manipulation of the given String for
the namespace is hard because people can use a lot of different combinations.
So if you have a simple expression like
{code}
/foo/bar
{code}
Then it may be possible to manipulate it beforehand and do
{code}
/c:foo/c:bar
{code}
And register c as a namespace with the uri from the XML message.
But when the xpath expression becomes more complex, its much harder.
So I wonder there must be better ways that this?
