XML::LibXML::NodeList(3)

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(@nodes)
You will almost never have to create a new NodeList 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.

  to_literal_delimited($separator)
Returns the concatenation of all the string-values of all the nodes in the list, delimited by the specified separator.

  to_literal_list()
Returns all the string-values of all the nodes in the list as a perl 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 NodeList.

  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($nodelist)
Given a nodelist, prepends the list of nodes in $nodelist to the front of the current list.

  map($coderef)
Equivalent to perl's map function.

  grep($coderef)
Equivalent to perl's grep function.

  sort($coderef)
Equivalent to perl's sort function.

Caveat: Perl's magic $a and $b variables are not available in $coderef. Instead the two terms are passed to the coderef as arguments.

  reverse()
Equivalent to perl's reverse function.

  foreach($coderef)
Inspired by perl's foreach loop. Executes the coderef on each item in the list. Similar to "map", but instead of returning the list of values returned by $coderef, returns the original NodeList.

  reduce($coderef, $init)
Equivalent to List::Util's reduce function. $init is optional and provides an initial value for the reduction.

Caveat: Perl's magic $a and $b variables are not available in $coderef. Instead the two terms are passed to the coderef as arguments.
