#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.
