[xml] Questions about libxml2's API...

[Roland Mainz <roland mainz nrubsig org>]

Hi!

----

I am currently working on SAX/xmlSAXParseFile libxml2 bindings for
ksh93/kash and have a few questions about the API:
- Is there a way to provide a "default encoding setting" which should be
used if the document itself doesn't define a character set ?

- How can I turn-off the libxml2 feature that it resolves all entities
(e.g. how can I do my own entity resolving) ?

- How can I abort a SAX parser run from within a callback function ?

- Is there a way to get |xmlSAXParseFile()| to accept stdin as input to
allow it's use in pipe chains ?

- Is |xmlSAXParseFile()| fully thread-safe (important since ksh93 will
get thread support soon) ?

- Is |xmlSAXParseFile()| re-entrant, e.g. can I call |xmlSAXParseFile()|
from within a callback during another |xmlSAXParseFile()| ? For example
for a simple RSS browser I would have to call |xmlSAXParseFile()| to
decode the RSS stream and then |xmlSAXParseFile()| a 2nd time (from
within a callback) to decode the XHTML data (I've already tried but
something weired is going on somehow the '<' and '>' characters seem to
"disappear" from the charatcer data stream).

Bye,
Roland
