[xml] what functions

["Marek Elsner" <marek icom pl>]

Hello,
I have got sth like:

        <animal>
                <tiger>ffff</tiger>
        </animal>

I would like to change content of <tiger> from "fff" to "ddd". I know that
there is possibility to unlink node tiger and after thar re-create it with
other content but I would like to make it without deleting it.
Is there a function making it in that way..?

I am working on RH 8.0, gcc 3.2, libxml2-2.4.23-1
