Re: [xml] manipulating tree causes Seg fault

[Nick Lang <nick lang propylon com>]

Michael,

You're right.

The sole reason for the creation of a new tree, and adding it in, then 
"peeling" the root of the new tree, is just the simplest way of doing it 
with the way the tools work that we have set up.

I agree with your proposed solution. What it sounds like is I might have 
to do some rewriting to the way our tools actually "peel" elements. 

My second question, is this (after working on this for a while).
Assuming we are using the same method I explained previously:
If a tree (called tree1) with a name space declaration is added to an 
existing tree (called tree2), with more name spaces (including the one 
from tree1). If the node, with the name space declaration from tree1 is 
removed, the the namespaced elements from tree1, now in tree2 should not 
be effected right?

Thanks
Nick
