Hi people,

I still haven't got an answer on my question to the XPath problem I
was having. In the meantime I've written my own Xpath query function,

  What you implemented is NOT XPath. You break the XPath semantic.
    //foo CANNOT select a node which has a namespace even if it's a
default namespace. This is the #1 question of all XPath beginners, not
only you felt in the trap, apparently you didn't checked archives and
decided to implemnent a broken implementation instead, sounds positively
awful !

If it's the number one question, then maybe that's tell you something about your implementation. If you get an xpath context from a document, shouldn't that xpath context have a default namespace which is the document's default name space?

My function works and yours didn't, how is that broken? Mine is also simpler to use and faster.

XML isn't the only language with namespaces. C++ has them, Java has them and even a class can be considered to be a "name space". In both these languages I don't need to explicitly state the full name. Why should XML be different?

In C++ I can do this:

string s = "hello";


std::string s = "hello";

But you think you know more about how name spaces should be used than the makers of Java and C++?

OK then.

I'd still like an answer on the XPath problem I posted here,
though. Because I'd like to use the standard tools whereever possible
instead of having to write my own alternatives.

So, I got this problem with xmlCopyNode, it's putting a namespace
into the XML, when I don't actually want one there.

You copy a namespaced element node you gate a namespaced element node the namespace is as important as the element name in a processor conformant to XML namespace. You're asking to create a different element, not a copy !

Except that it is a copy, because it's going into a document with the same name space.
