[xml] Managing libxml2's on the fly created nodes

[Holger Franzen <newsgroups k681 de>]

Hi everybody,

i'm working in a c++ environment with on top of the xmlNode builded
objects using the nodes _private pointer. When processing xhtml i've
noticed that libxml2 is adding nodes on the fly to the document.

like this one:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

I searched the api and the archives but did not find an answer on howto
track these added nodes. Is there a callback or something?

Thank's in advance,
Holger.
