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

Synopsis

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

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)
