I am pretty sure the answer is no but of course there are cleverer guys than me!
Is there a way to construct a lazy SAX based XML parser that can be stopped (e.g. raising an exception is a possible way of doing this) but also resumable ?
I am looking for a possible solution for Python >= 2.6 with standard XML libraries. The "lazy" part is also trivial: I am really after the "resumable" property here.
Expat can be stopped and is resumable. AFAIK Python SAX parser uses Expat. Does the API really not expose the stopping stuff to the Python side?? 
EDIT: nope, looks like the parser stopping isn't available from Python...
