NAME
XML::XPath::NodeSet - a list of XML document nodes
DESCRIPTION
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.
