Does anyone know where I can find a simple, portable html parser? It
would be great if it could parse html into an S-expression like:
(:html (:head (:title "Example HTML input"))
(:body (:p ...
There is a parser available at http://opensource.franz.com/xmlutils/
which looks great but seems to only work with Allegro (I use Clisp).

You should check CL-XML

CL-XML is not portable - it does not work with Clisp :-(

I'd say it has not been "ported". I do not know why it shouldn't be
"portable".

Hmm - I usually interpret "portable" to be "runs on compliant
platforms" not "can be ported" -- that would be
"port-able"

a program can not only purport to be portable, but also to be a conforming
program, yet, in practice, "to depend for its correctness only upon documented
aspects of common lisp" will not suffice to guarantee its correct functioning
in a new implementation given that there are any number of things which common
lisp does not specify, and that there is always a disjunction between a
purportedly conforming common lisp implementation and the standard.

it depends on what one means by "html". cl-xml, as released, is intended for
encodings like xhtml. that is, for html which is "well-formed". if you need to
parse earlier versions of html, with abbreviated attributes and unterminated
elements, you'll have to change the bnf to permit undelimted or absent
attribute values and include a heuristic to recognize unterminated elements.
the bnf directory contains a start at an html grammar, but html exhibits a
wide range of variations and you may need to change what's there to suit your source.

as released, cl-xml is intended to parse to a clos document model. if you need
to parse to s-expressions, look in the directory #p"xml:demos;xcl;". it shows
one way to augment the parser's internal construction functions to generate
s-expressions rather than instances. again, as opinions vary on the
appropriate s-expression representation for markup, you may need to modify
what's there.

i've never tried to port it to clisp. if one needs to use it with an open
source lisp, openmcl and cmucl are know to work. if someone has experience
with clisp, please let me know.
...
I `de-Allegroized' (`ported' would be an overstatement) phtml.cl some
time ago, so I could use it with CMUCL. Send me a mail if you want me
to dig it up for you. But be warned that is is based on v 1.18, dated
2000/08/16. Not to mention that it is untested, may only work with
CMUCL, or not at all.
