Re: [xml] strange transformCtxt free-ing problem

shows this for every document I get back that parses:

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.


This is inside a document loader implementation. The parser context is
passed in, here's the function 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

And here's the set:

    try:
        libxslt.setLoaderFunc(loader)
    except Exception, e:
        # Whoops! serious error


Note the pctx in the loader arg list.
        



      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.



From a loader?


I thought it was not possible. I'll try it and see!
