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>))
