NAME ^

XML::LibXML::NodeList - a list of XML document nodes

DESCRIPTION ^

An XML::LibXML::NodeList object contains an ordered list of nodes, as detailed by the W3C DOM documentation of Node Lists.

SYNOPSIS ^

  my $results = $dom->findnodes('//somepath');
  foreach my $context ($results->get_nodelist) {
    my $newresults = $context->findnodes('./other/element');
    ...
  }

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, 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.
