Hi everyone,

I read the source, made numerous tests, but SGMLParser's keeps returning *tag* 
data 
from previous parser instances. I'm totally confused why.. The content data it
returns is ok.

E.g.::

    sp = MyParser()
    sp.feed('<test><t />Test</test>')
    print sp.content, sp.markup
    sp.close()

    sp = MyParser()
    sp.feed('<xml>\n</xml>\r\n')
    print sp.content, sp.markup
    sp.close()

gives::

    ('Test', [{'t': ({}, (0, 0))}, {'test': ({}, (0, 4))}]) 
    ('\n\r\n', [{'t': ({}, (0, 0))}, {'test': ({}, (0, 4))}, {'xml': ({}, (0, 
1))}])

It keeps the tags from the previous session, while i'm sure the stack etc.
should be clean..

Any ideas?


regards, Berend
