API
new()

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 $pos. The node position in
XPath is based at 1, not 0.
size()
Returns the number of nodes in the NodeList.
pop()
Equivalent to perl’s pop function.
push(@nodes)
Equivalent to perl’s push function.
append($nodelist)
Given a nodelist, appends the list of nodes in
$nodelist to the end of the current list.
