XML::LibXML::NodeList - a list of XML document nodes
An XML::LibXML::NodeList object contains an ordered list of nodes, as detailed by the W3C DOM documentation of Node Lists.
my $results = $dom->findnodes('//somepath');
foreach my $context ($results->get_nodelist) {
my $newresults = $context->findnodes('./other/element');
...
}
new()You will almost never have to create a new NodeSet object, as it is all done for you by XPath.
get_nodelist()Returns a list of nodes, the contents of the node list, as a perl list.
string_value()Returns the string-value of the first node in the list. See the XPath specification for what ``string-value'' means.
to_literal()Returns the concatenation of all the string-values of all the nodes in the list.
get_node($pos)Returns the node at $pos. The node position in XPath is based at 1, not 0.
size()Returns the number of nodes in the NodeSet.
pop()Equivalent to perl's pop function.
push(@nodes)Equivalent to perl's push function.
append($nodelist)Given a nodelist, appends the list of nodes in $nodelist to the end of the current list.
shift()Equivalent to perl's shift function.
unshift(@nodes)Equivalent to perl's unshift function.
prepend($nodeset)Given a nodelist, prepends the list of nodes in $nodelist to the front of the current list.
iterator()Will return a new nodelist iterator for the current nodelist. A nodelist iterator is usefull if more complex nodelist processing is needed.
