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>))
