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.  

string_value()

Returns the string-value of the first node in the list. See the XPath specification for what ``string-value'' means.  

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.
