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.
