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>))
