NAME

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

SYNOPSIS

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();

DESCRIPTION

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>))
