NAME
XML::XPath::NodeSet - a list of XML document nodesDESCRIPTION
An XML::XPath::NodeSet object contains an ordered list of nodes. The nodes each take the same format as described in XML::XPath::XMLParser.SYNOPSIS
my $results = $xp->find('//someelement'); if (!$results->isa('XML::XPath::NodeSet')) { print "Found $results\n"; exit; } foreach my $context ($results->get_nodelist) { my $newresults = $xp->find('./other/element', $context); ... }
API
new()
You will almost never have to create a new NodeSet object, as it is all done for you by XPath.get_nodelist()
Returns a list of nodes. See XML::XPath::XMLParser for the format of the nodes.string_value()
Returns the string-value of the first node in the list. See the XPath specification for what ``string-value'' means.to_literal()
Returns the concatenation of all the string-values of all the nodes in the list.get_node($pos)
Returns the node at $pos. The node position in XPath is based at 1, not 0.size()
Returns the number of nodes in the NodeSet.pop()
Equivalent to perl's pop function.push(@nodes)
Equivalent to perl's push function.append($nodeset)
Given a nodeset, appends the list of nodes in $nodeset to the end of the current list.shift()
Equivalent to perl's shift function.unshift(@nodes)
Equivalent to perl's unshift function.prepend($nodeset)
Given a nodeset, prepends the list of nodes in $nodeset to the front of the current list.Contenus ©2006-2024 Benjamin Poulain
