foreach my $context ($results->get_nodelist) {
my $newresults = $context->findnodes('./other/element');

}
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, 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.
get_node($pos)
Returns the node at CW$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($nodelist)
Given a nodelist, appends the list of nodes in CW$nodelist to the end of the current list.
shift()
Equivalent to perl's shift function.
unshift(@nodes)
Equivalent to perl's unshift function.
prepend($nodeset)
Given a nodelist, prepends the list of nodes in CW$nodelist to the front of the current list.
iterator()
Will return a new nodelist iterator for the current nodelist. A nodelist iterator is usefull if more complex nodelist processing is needed.
