XML::XPathEngine::NodeSet(3)   User Contributed Perl Documentation   XML::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.
