[PRL] Re: prl page

[Felix S Klock II]

Also, in case you're interested in reading in other people's webpages 
and then munging that content using Scheme functions...

Neil Van Dyke wrote some code for parsing HTML and returning an 
SXML-form for the parsed webpage.
See:
http://www.neilvandyke.org/htmlprag/

and I wrote a wrapper module for MzScheme that turns the SXML-form into 
a MzScheme-style X-expression.
See:
http://www.pnkfx.org/~pnkfelix/CodePost/links/Dev/scheme/code/vandyke/
(note that the latter is not complete; it uses the (INCLUDE ...) form 
to "link" Neil's htmlprag.scm file)
