XML::XPathEngine::NodeUser3Contributed Perl DocumeXML::XPathEngine::NodeSet(3)

NAME
       XML::XPathEngine::NodeSet - a list of XML document nodes

DESCRIPTION
       An XML::XPathEngine::NodeSet object contains an ordered list of nodes.
       The nodes each take the same format as described	in
       XML::XPathEngine::XMLParser.

SYNOPSIS
	       my $results = $xp->find('//someelement');
	       if (!$results->isa('XML::XPathEngine::NodeSet'))	{
		       print "Found $results\n";
		       exit;
	       }
	       foreach my $context ($results->get_nodelist) {
		       my $newresults =	$xp->find('./other/element', $context);
		       ...
	       }

API
   new()
       You will	almost never have to create a new NodeSet object, as it	is all
       done for	you by XPath.

   get_nodelist()
       Returns a list of nodes.	See XML::XPathEngine::XMLParser	for the	format
       of the nodes.

   string_value()
       Returns the string-value	of the first node in the list.	See the	XPath
       specification for what "string-value" means.

   string_values()
       Returns a list of the string-values of all the nodes in the list.

   to_literal()
       Returns the concatenation of all	the string-values of all the nodes in
       the list.

   get_node($pos)
       Returns the node	at $pos. The node position in XPath is based at	1, not
       0.

   size()
       Returns the number of nodes in the NodeSet.

   pop()
       Equivalent to perl's pop	function.

   push(@nodes)
       Equivalent to perl's push function.

   append($nodeset)
       Given a nodeset,	appends	the list of nodes in $nodeset to the end of
       the current list.

   shift()
       Equivalent to perl's shift function.

   unshift(@nodes)
       Equivalent to perl's unshift function.

   prepend($nodeset)
       Given a nodeset,	prepends the list of nodes in $nodeset to the front of
       the current list.
