[xslt] intercepting xmlFreeNode?

["Oleg A. Paraschenko" <olpa xmlhack ru>]

  Hello,

  I'm writing an XSLT extension function, which collects pointers to nodes
for a later use. Unfortunately, sometimes libxslt frees the nodes which
are collected, so the pointers become corrupted and my program crashes.

  Is there any way to intercept xmlFreeNode or to notice that the nodes go
away?
