NAMEXML::XPath::NodeSet − a list of XML document nodes
DESCRIPTIONAn 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. 0
