NAME
XML::LibXML::NodeList - a list of XML document nodesDESCRIPTION
An XML::LibXML::NodeList object contains an ordered list of nodes, as detailed by the W3CDOM
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.
