XML Tools

If I wanted to write a Markup language interpreter in Common Lisp, what tools would I need?

What exactly is a "Markup language interpreter"? You can see a list of XML tools on Cliki. I believe the best parser is CXML and it's extensions.

Thank you.

Is there a good online tutorial explaining the basics of writing an interpreter for an XML-Based language (writing an XML parser(?)) ?

XML is surprisingly complicated. You don't want to undertake writing a new parser without good reason. The "lightweight" parsers (e.g. stuff like tinyxml or rapidxml) don't support large subsets of the spec (e.g. entities and validation).

Here's a fairly good intro.

So do you think writing an AIML parser will be quite difficult?

Not really if you use CXML or CL-XML. With CXML you are advised to use KLACKS which is a SAX-like parser.
