goto USE CASE
Witt,
A very nice construct that is far superior to GOTO is CASE. CASE also prevents dead ends and allows for many outcomes depending on the variable.
You can set it up to have infinite conditions, 256 max I believe, to perform various tasks depending on the input to the CASE statement.
Just define $VAR above from some action and CASE will do the rest!
case $VAR in
VAR1 ) Do some statement ;;
VAR2 ) Do different statement ;;
VAR3 ) Do another different statement;;
* ) Do default statement and exit from CASE ;;
esac

rdf::redland::statement
RDF::Redland::Statement(3pm) User Contributed Perl Documentation RDF::Redland::Statement(3pm) NAME
RDF::Redland::Statement - Redland RDF Statement Class SYNOPSIS
use RDF::Redland; my $statement1=new RDF::Redland::Statement($statement); my $statement2=new RDF::Redland::Statement($subject,$predicate,$object); ... if($statement->subject->equals($node)) { ... } DESCRIPTION
Manipulate RDF statements which comprise three RDF::Redland::Node objects. Also used for partial statements which can have empty parts and are used for matching statements in statement queries of the model - see the RDF::Redland::Model. CONSTRUCTORS
new NODE NODE NODE|STATEMENT Create a new statement from nodes or copy an existing statement. If three NODEs are given, make a new statement from them. Each Node can be a Redland::RDF:Node, a Redland::RDF::URI, a perl URI or a string literal. Otherwise STATEMENT must be an existing statement to copy. clone Copy a RDF::Redland::Statement. METHODS
subject [SUBJECT] Get/set the statement subject. When a RDF::Redland::Node SUBJECT is given, sets the subject of the statement, otherwise returns a reference to the statement RDF::Redland::Node subject. predicate [PREDICATE] Get/set the statement predicate. When RDF::Redland::Node PREDICATE is given, sets the predicate of the statement, otherwise returns a reference to the statement RDF::Redland::Node predicate. object [OBJECT] Get/set the statement object. When RDF::Redland::Node OBJECT is given, sets the object of the statement, otherwise returns a reference to the statement RDF::Redland::Node object. as_string Return the statement formatted as a string (UTF-8 encoded). equals STATEMENT Return non zero if this statement is equal to STATEMENT OLD METHODS
new_from_nodes SUBJECT PREDICATE OBJECT Create a new RDF::Redland::Statement with the given RDF::Redland::Node objects as parts (or undef when empty for a partial statement). Use instead: $a=new RDF::Redland::Statement($subject, $predicate, $object); new_from_statement STATEMENT Create a new RDF::Redland::Statement object from RDF::Redland::Statement STATEMENT (copy constructor). Use instead: $s=$old_statement->clone; SEE ALSO
