XML/HTML parsers

Description

The HTML parser converts HTML to a format we call lhtml which is a natural encoding of HTML in Lisp lists. lhtml can be converted back into HTML using the htmlgen package that's part of AllegroServe.

The XML parser is a non-validating parser that converts XML into lxml, a format similar to lhtml.

Platform

The HTML parser works on Allegro Common Lisp versions 5.0.1 and later although if your HTML code includes 16-bit character entities the parser will only be able to represent these characters in the International version of Allegro Common Lisp version 6.0 or later.

The XML parser works on Allegro Common Lisp versions 6.0 or later as it requires Unicode support.

Building

The HTML parser need only be compiled and loaded into Lisp.

To build the XML parser, load build.cl.
