NAME

       XML::LibXML::RegExp - 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)) { ... }

	 $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 <http://www.w3.org/TR/REC-xml/#determinism>))
