Thanks ! I did test it successfully too yet. However iterpase is not supported :( So i can not parse large file (>100Mo) ...?! I am trying to mix celementtree and lxml right now !!
lxml right now is not optimal for parsing such large files. Support for iterparse would be nice though likely a lot of work, and full xpath support in that context might be extremely hard to accomplish.
libxml2 does seem to have something called 'streaming xpath' that might be useful in this area though (but this is not yet exposed to lxml either).
I dunno if this can help, but Libxml2 has the pattern.c module, which is, amongst others, used by the xmlschemas.c module for the XPaths of identity-constraints. It is streamable, but supports only a minimal subset of XPath: only element and attribute tests without predicates, and only the child and descendant-or-self axis. An example would be: ".//foo/boo/@bar" - and that's it already. Regards, Kasimier
