  okay. that's the important point.

 what is pctx ??? i find suspicious the fact you could provide a C parser
context here.

  just use htmlReadFile and forget about trying to address directly the
parser context. With python overhead you won't gain anything to create
a separately accessible object. The less you touch things though Python
the better it will be, really. That said HTML parsing works for me when
using htmlReadFile.
