XML::LibXML::NodeList(3)       User Contributed Perl Documentation       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.

   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.
