ElementTree and DTDs

[J. Pablo Fernández]

Hello,

Is ElementTree supposed to load DTDs? I have some xmls heavy on
entities and it fails this way:

Python 2.5.2 (r252:60911, Apr 21 2008, 11:12:42)

Thanks.

Or is there another library that would handle DTDs correctly,
performing entity replacements?

Thanks.

AFAIR, you have to provide entities by hand.

Or is there another library that would handle DTDs correctly,
performing entity replacements?
