(Go to my E2 tool index)
E2 doesn't allow external links to be used, but ocassionally people have HTML document at hand with just a couple of links that they'd like to node (for example, a +5, Insightful Slashdot comment or 4.91 / 12 Kuro5hin comment, or something of slightly less rated by others but of equal worthiness in metaphysical sense).
This program takes a HTML document and "unlinks" it (adding footnote numbers), adding all links it found to the end of the document.
;;; This "Unlinks" a HTML document - it removes all hypertext anchors
;;; from the text, inserts superscript numbers, and creates a
;;; list of those links to the end of the document.
;;; Be sure to remove all those links from the document that you don't
;;; want to list in the end, because otherwise clearing the list up
;;; makes numbers go out of synch And That Isn't Fun.
;;; Not tested with links that go to multiple lines...
;;; Distributed under the Artistic Lisence.
