hi.
my parser reads a document and while it does this there might come
some "tag" that should make the object doing the job to get deleted.
whatever if i delete the memory that holds the document my
application crashs (probably because the document was not finished...
example:
static void x_endElement(void *ctx,const xmlChar *fullname)
{
...
</some special element>
xmlFreeParserCtxt(((myclass*)ctx)->ptxmlParserCtx);
// or maybe even
delete (myclass*)ctx;
...
}
this crashs my app. how do i delete/free the memory of the parser if
a special event (in the doc) appears?
You can't do that ! Sax is callback based. You cannot break the flow of
control from *within* a callback. Check xmlStopParser() but you simply
can't destroy the parser when you're called from within the parser !
