Re: [xml] strange transformCtxt free-ing problem

Could you provide the file ("file2.html") that you are using for this
test which fails?  If I use a file like libxml2/test/HTML/doc2.htm:

bill bbopt ~/gnomesvn/work $ ln -s HTML/doc2.htm file2.html
bill bbopt ~/gnomesvn/work $ python bug.py
./file2.html:10: HTML parser error : Misplaced DOCTYPE declaration
<!-- END Naviscope Javascript --><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML
4.0 Tra
                                 ^
<?xml version="1.0"?>
<html>
  <head/>
  <body>
    <div>
<!-- saved from url=(0016)http://intranet/ -->
<!-- BEGIN Naviscope Javascript -->
<!-- END Naviscope Javascript -->
<!-- saved from url=(0027)http://www.agents-tech.com/ -->
    </div>
    <div>this is xml</div>
  </body>
</html>

which seems to indicate that at least something is working :-).

(note that I'm using the latest SVN for both libxslt and libxml2)

  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.

  doc.dump(sys.stdout)

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:

  def loader(url, pctx, ctx, type):
      doc = None
      context_object = None
      if type:
          context_object = libxslt.stylesheet(_obj=ctx)
      else:
          context_object = libxslt.transformCtxt(_obj=ctx)
      # The parserContext and resulting document
      parserContext = libxml2.parserCtxt(_obj=pctx)
      doc = None
      if url == "/one":
          doc = parserContext.htmlCtxtReadFile("file2.html", "UTF8", 1)
      else:
          doc = parserContext.ctxtReadDoc("""<document>
  <h1>this is xml</h1>
  </document>""", url, "UTF8", 0)
      return doc


so when I ask for "/one" from my stylesheet I get back (practically)
nothing.
