Devised by Aaron Watters in the bad old days before Python had fast
parsers available. Constructs the lightest possible in-memory
representation; parses most files we have seen in pure python very
quickly.
The output structure is the same as the one produced by pyRXP,
our validating C-based parser, which was written later. It will
use pyRXP if available.
This is used to parse intra-paragraph markup.
Example parse::
text in xml
( "this",
{"type": "xml"},
[ "text ",
("b", None, ["in"], None),
" xml"
]
None )
{ 0: "this"
"type": "xml"
1: ["text ",
{0: "b", 1:["in"]},
" xml"]
}
Ie, xml tag translates to a tuple:
(name, dictofattributes, contentlist, miscellaneousinfo)
where miscellaneousinfo can be anything, (but defaults to None)
(with the intention of adding, eg, line number information)
special cases: name of "" means "top level, no containing tag".
Top level parse always looks like this::
("", list, None, None)
contained text of None means
In order to support stuff like::
AT THE MOMENT & ETCETERA ARE IGNORED. THEY MUST BE PROCESSED
IN A POST-PROCESSING STEP.
PROLOGUES ARE NOT UNDERSTOOD. OTHER STUFF IS PROBABLY MISSING.
