  But did you update libxslt too and make install for it too ? Please do
he fixed the problems in libxslt not in libxml2,


Ah!

Yes. It stopped segfaulting. I can't get it to parse the HTML... but
it has stopped segfaulting.


  okay. that's the important point.


shows this for every document I get back that parses:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd";>

Here's the relevant bit of the loader again:

      # The parserContext and resulting document
      parserContext = libxml2.parserCtxt(_obj=pctx)


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


      doc = None
      if url == "/one":
          doc = parserContext.htmlCtxtReadFile("file2.html", "UTF8", 1)
      else:
          doc = parserContext.ctxtReadDoc("""<document>


  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.
