Hi Kent,
Well I have decided to get this sorted once and for all. Not that I
don't like ElementTree, but the fack is that BeautifulSoup uses a near
identical syntax to the 3D application SDK's object model I'm using it
with, making interaction between the 3D and the XML extremely
transparent. Anyway, here is what I did.
I simply modified the BeautifulSoup class, and added my own nestable
tags to the list of NESTABLE_BLOCK_TAGS:
NESTABLE_BLOCK_TAGS = ['blockquote', 'div', 'fieldset', 'ins', 'del']
became
NESTABLE_BLOCK_TAGS = ['blockquote', 'div', 'fieldset', 'ins', 'del',
'sceneobject', 'parameters', 'parameter', 'shader']
Not super-elegant but it works. I wrote to the author but did not get an answer.
Thanks everyone!
Bernard
