📛 NAME

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

🚀 Quick Reference

📝 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.
