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

NAME

       XML::LibXML::XPathExpression - XML::LibXML::XPathExpression - interface to libxml2 pre-compiled XPath expressions

SYNOPSIS

	 use XML::LibXML;
	 my $compiled_xpath = XML::LibXML::XPathExpression->new('//foo[@bar="baz"][position()<4]');

	 # interface from XML::LibXML::Node

	 my $result = $node->find($compiled_xpath);
	 my @nodes = $node->findnodes($compiled_xpath);
	 my $value = $node->findvalue($compiled_xpath);

	 # interface from XML::LibXML::XPathContext

	 my $result = $xpc->find($compiled_xpath,$node);
	 my @nodes = $xpc->findnodes($compiled_xpath,$node);
	 my $value = $xpc->findvalue($compiled_xpath,$node);

	 $compiled = XML::LibXML::XPathExpression->new( xpath_string );

DESCRIPTION

       This is a perl interface to libxml2's pre-compiled XPath expressions.  Pre-compiling an XPath expression can give in some performance
       benefit if the same XPath query is evaluated many times. "XML::LibXML::XPathExpression" objects can be passed to all "find..." functions
       "XML::LibXML" that expect an XPath expression.

       new()
	     $compiled = XML::LibXML::XPathExpression->new( xpath_string );

	   The constructor takes an XPath 1.0 expression as a string and returns an object representing the pre-compiled expressions (the actual
	   data structure is internal to libxml2).
