[xml] remove node from html document

[andrew james <andrew systemssingular com>]

I have tried to xmlUnlinkNode, the result is that the loop 
through all nodes is stopped at the unlinked node.

What is the reason for that stop?

My amature observation is that the structure of a document 
in the xmlNodePtr is not rewritten per xmlUnlinkNode?

I have the a program that partially works, the only problem 
part is that the loop all nodes stops at an unlink.  The 
program can write the final document with the first found 
specific node disposed and all nodes after it are there 
(therefore the structure of the document is not lost after 
the unlink).

The problem is that I want the loop to continue to find more 
nodes after the first unlink, to unlink nodes with specific 
values indefinitely.

I may have the wrong funct.  What is the recommended method 
to remove (dispose, unlink, delete, less, whatever its 
called) a node (and all sub nodes) ?


thank you
