SGMLS 1.03ii

SGMLS is a Perl class for postprocessing the output from the sgmls and nsgmls parsers. SYNOPSIS use SGMLS; my $parse = new SGMLS(STDIN); my $event = $parse->next_event; while ($event) { SWITCH: { ($event->type eq start_element) && do { my $element = $event->data; # An object of class SGMLS_Element [[your code for the beginning of an element]] last SWITCH; }; ($event->type eq end_element) && do { my $element = $event->data; # An object of class SGMLS_Element [[your code for the end of an element]] last SWITCH; }; ($event->type eq cdata) && do { my $cdata = $event->data; # A string [[your code for character data]] last SWITCH; }; ($event->type eq sdata) && do { my $sdata = $event->data; # A string [[your code for system data]] last SWITCH; }; ($event->type eq re) && do { [[your code for a record end]] last SWITCH; }; ($event->type eq pi) && do { my $pi = $event->data; # A string [[your code for a processing instruction]] last SWITCH; }; ($event->type eq entity) && do { my $entity = $event->data; # An object of class SGMLS_Entity [[your code for an external entity]] last SWITCH; }; ($event->type eq start_subdoc) && do { my $entity = $event->data; # An object of class SGMLS_Entity [[your code for the beginning of a subdoc entity]] last SWITCH; }; ($event->type eq end_subdoc) && do { my $entity = $event->data; # An object of class SGMLS_Entity [[your code for the end of a subdoc entity]] last SWITCH; }; ($event->type eq conforming) && do { [[your code for a conforming document]] last SWITCH; }; die "Internal error: unknown event type " . $event->type . "n"; } $event = $parse->next_event; } The SGMLS package consists of several related classes: see "SGMLS", "SGMLS_Event", "SGMLS_Element", "SGMLS_Attribute", "SGMLS_Notation", and "SGMLS_Entity". All of these classes are available when you specify use SGMLS; Generally, the only object which you will create explicitly will belong to the SGMLS class; all of the others will then be created automatically for you over the course of the parse. Much fuller documentation is available in the .sgml files in the DOC/ directory of the SGMLS.pm distribution..
