[wwwsearch-general] ClientForm request re ParseErrors

[bruce]

update.....

out of curiosity, i fetched the latest mechanize from svn.. i get the same
error with the parse...

i've also tried to do:
 br.select_form(nr = 1)
 br.select_form(name="foo")
 br.select_form(name=foo)
 br.select_form(name="foo")

etc.... same err occurs...

i can tell, i've followed the docs.. but i could be wrong. any thoughts?

the code, output, and partial html is below...

thoughts/comments/ideas/etc...

  #get the semester page
  #get the 2nd semester/frame src url page
  br.open(url)
  response = br.response()  # this is a copy of response
  s = response.read()
  print response.read()
  print s
  #we now have the semester page...
  d = libxml2dom.parseString(s, html=1)
  ff = d.xpath(fnamepath)
  fname = ff[0].nodeValue
  print "fname = ",fname
  br.select_form(name="main")<<<<<<<<<<<<<<< error happens....

No, I just hate going one char at a time in Python.  Surely this should be
fixed somewhere else?  (I'm not sure where; I haven't looked recently)

If you've determined that fixing it elsewhere pulls in too much code or
requires a fix to stdlib code (if so, why?), maybe I should do as you
suggest anyway, but I don't like it.

Why?  You can supply your own FormsFactory, as DefaultFactory does.

Oh.  Sure, if I apply a patch to enable ignore_errors, I'll of course do
that too.
