Hi list,

I'm new to libxml and need some help.

What I try to do is to extend an existing xml-document with a new root
node. I've already tried some things...

To illustrate the "problem", the actual xml file is something like the
following:



Call this doc1


<?xml version="1.0"?>
<data>

[snip]

</data>

And the goal should be:



And this is doc2


<?xml version="1.0"?>
<protocol>
  <head>
  </head>
  <body>
    <data>

[snip]

    </data>
  </body>
</protocol>

What is the best way to achieve this?
Perhaps it is relevant that the xml-tree will never be written out to a
file. It's processed "in memory".




From doc1 use xmlDocGetRootElement to get the xmlNodePtr for the root

node (<data>). Then in doc2 walk the tree*, and when you got to <body>,
use xmlAddChildList to add the root node tree bit from doc1.

Cheers,
John
