You're right, they do seem to get updated continuously. I didn't even
try checking this because the documentation explicitly says these values
won't be valid unless the parser raises an xml.parsers.expat.ExpatError
exception.

ie, http://python.org/doc/current/lib/xmlparser-objects.html says:

  The following attributes contain values relating to the most recent
  error encountered by an xmlparser object, and will only have correct
  values once a call to Parse() or ParseFile() has raised a
  xml.parsers.expat.ExpatError exception.

  ErrorByteIndex
    Byte index at which an error occurred.

  ...

  ErrorColumnNumber
    Column number at which an error occurred.

  ErrorLineNumber
    Line number at which an error occurred.

So is this an error in the documentation, or is the fact that these
values are continuousy updated merely a "quirk" in the current behaviour
that I shouldn't rely on because it may change at some point in the
future?

I'd be much happier if the docs didn't say that I can't do what I want
to do...
