I'm not clear if you want auto-conversion for a single method, or PyKDE-wide
auto-conversion. In either case, I think I'd probably give the same answer.
There are probably several hundred khtml methods that take DOM.DOMString as
an argument. Conversion could be done with handwritten code, but that's a
considerable amount to generate and maintain. There might be some other way
to do it that's workable - I'd have to give that some thought.
In the meantime, the easiest way to handle it would be to subclass (in Python)
the class that contains the method(s). For example:
class PyHtmlDocument (DOM.HTMLDocument):
def getElementsByTagName (self, pyString):
return DOM.HTMLDocument.getElementsByTagName (self,
DOM.DOMString (pyString))

In configure.py, generate_code (), add:
if mname == "khtml":
argv.append("-e")
That should generate Python exceptions for any C++ exceptions anywhere in
khtml. I'll modify configure.py to do that for the next release.
