=head1 NAME

XML::XPathEngine::NodeSet - a list of XML document nodes

=head1 DESCRIPTION

An XML::XPathEngine::NodeSet object contains an ordered list of nodes. The nodes
each take the same format as described in L<XML::XPathEngine::XMLParser>.

=head1 SYNOPSIS

	my $results = $xp->find('//someelement');
	if (!$results->isa('XML::XPathEngine::NodeSet')) {
		print "Found $results\n";
		exit;
	}
	foreach my $context ($results->get_nodelist) {
		my $newresults = $xp->find('./other/element', $context);
		...
	}

=head1 API

=head2 new()

You will almost never have to create a new NodeSet object, as it is all
done for you by XPath.

=head2 get_nodelist()

Returns a list of nodes. See L<XML::XPathEngine::XMLParser> for the format of
the nodes.

=head2 string_value()

Returns the string-value of the first node in the list.
See the XPath specification for what "string-value" means.

=head2 string_values()

Returns a list of the string-values of all the nodes in the list.


=head2 to_literal()

Returns the concatenation of all the string-values of all
the nodes in the list.

=head2 get_node($pos)

Returns the node at $pos. The node position in XPath is based at 1, not 0.

=head2 size()

Returns the number of nodes in the NodeSet.

=head2 pop()

Equivalent to perl's pop function.

=head2 push(@nodes)

Equivalent to perl's push function.

=head2 append($nodeset)

Given a nodeset, appends the list of nodes in $nodeset to the end of the
current list.

=head2 shift()

Equivalent to perl's shift function.

=head2 unshift(@nodes)

Equivalent to perl's unshift function.

=head2 prepend($nodeset)

Given a nodeset, prepends the list of nodes in $nodeset to the front of
the current list.
