extract_links
$h->extract_links([types])
Retrieves the links contained within an element
and all of its child elements. This method returns a reference
to an array in which each element is a reference to an array
with two values: the value of the link and a reference to the
element in which it was found. You may specify the tags from
which you want to extract links by providing their names in a
list of types.
