XML::LibXML::RegExp - XML::LibXML::RegExp - interface to libxml2 regular expressions

use XML::LibXML; my $compiled_re = XML::LibXML::RegExp->new([0-9]{5}(-[0-9]{4})?); if ($compiled_re->isDeterministic()) { … } if ($compiled_re->matches($string)) { … } $compiled_re = XML::LibXML::RegExp->new( $regexp_str ); $bool = $compiled_re->matches($string); $bool = $compiled_re->isDeterministic();

This is a perl interface to libxml2’s implementation of regular expressions, which are used e.g. for validation of XML Schema simple types (pattern facet).

new()

$compiled_re = XML::LibXML::RegExp->new( $regexp_str ); The constructor takes a string containing a regular expression and returns a compiled regexp object.

matches($string)

$bool = $compiled_re->matches($string); Given a string value, returns a true value if the value is matched by the compiled regular expression.

isDeterministic()

$bool = $compiled_re->isDeterministic(); Returns a true value if the regular expression is deterministic; returns false otherwise. (See the definition of determinism in the XML spec (http://www.w3.org/TR/REC-xml/#determinism))
