[xml] xmlTextReader namespaces and subtrees

[Cornelius Hald <hald icandy de>]

Hi,

I have a xml document with a namespace on the root element. I'm parsing
that and save a subtree of this document for later usage in memory.
Later I create a new xmlTextReader to parse the saved subtree. Which
after modifying I want to merge back into the main document.

When parsing the subtree I get a namespace error, probably because the
subtree does not have a namespace definition on its root element.
How can I solve this issue?

I have some ideas, but they are not complete, so help would really be
welcome!

- I could add the namespace manually to the root element of the subtree,
but I'm not sure how to remove the redundant namespace definitions later
when I merge the subtree with the main document again.

- Maybe I could tell the xmlTextReader via some API that the namespace
exists. But I couldn't find this API.

- Last but not least, maybe I can tell the reader to ignore namespace
errors, but again, I couldn't find out how.

It would really be nice if someone could help me, as this is the last
big showstopper before I can make a new realease :)

Thanks
Conny
