NAME

XML::XPath::NodeSet - a list of XML document nodes


DESCRIPTION

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


SYNOPSIS

        my $results = $xp->find('//someelement');
        if (!$results->isa('XML::XPath::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::XPath::XMLParser for the format of the nodes.


to_literal()

Returns the concatenation of the string-value of all the nodes in the list. See the XPath specification for what ``string-value'' means.


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.
