I don't have any trick for the problem original poster raised,
but whenever possible, I'd recommend against any "disk grounded"
round-trips.

Assuming the whole logic leveraging libxml2 can share the same
program, it can be turned into:

- dump to buffer (e.g. xmlDocDumpFormatMemory)
- do something with buffer (e.g. string replacement)
- read buffer back (e.g. xmlReadDoc)
- continue as if the original DOM was used
  (forget about using previously stored references to the original
  DOM for any identity checking purposes, amongst other Don'ts...)
