[libxml++] Namespace support in Node::find

[oystein homelien no]

I could not get Node::find to properly find things I were looking for in a
document with two namespaces in use.  The following patch "fixed it".  Am
I missing something, or is this missing in libxml++? (please reply
directly, i am not on the list)
