=head1 DESCRIPTION
|
529
|
|
|
|
|
|
|
|
530
|
|
|
|
|
|
|
This is an implementation of a SAX2 driver sitting on top of Expat
|
531
|
|
|
|
|
|
|
(XML::Parser) which Ken MacLeod posted to perl-xml and which I have
|
532
|
|
|
|
|
|
|
updated.
|
533
|
|
|
|
|
|
|
|
534
|
|
|
|
|
|
|
It is still incomplete, though most of the basic SAX2 events should be
|
535
|
|
|
|
|
|
|
available. The SAX2 spec is currently available from L.
|
536
|
|
|
|
|
|
|
|
537
|
|
|
|
|
|
|
A more friendly URL as well as a PODification of the spec are in the
|
538
|
|
|
|
|
|
|
works.

Turning one of the first two on also turns the other on (this maps
|
558
|
|
|
|
|
|
|
to the XML::Parser ParseParamEnts option). This may be fixed in the
|
559
|
|
|
|
|
|
|
future, so don't rely on this behaviour.

|
|
|
|
|
XML::Parser has no listed callbacks for the following events, which
|
566
|
|
|
|
|
|
|
are therefore not presently generated (ways may be found in the
|
567
|
|
|
|
|
|
|
future):
|
568
|
|
|

|
|
|
|
|
|
|
* ignorable_whitespace

* skipped_entity

Ways of signalling them are welcome. In addition to those,

575
|
|
|
|
|
|
|
set_document_locator is not yet called.
