XML::LibXML::RegExp(3)                     User Contributed Perl Documentation


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>))
