I've copied this from a post I sent to the Python XML-SIG.  It's a small
example of getting an html file and parsing it lightly to extract some
specific data.

<extract>
Actually, REBOL looks very interesting.  There isn't enough documentation as
yet so the learning curve is on the steep side.  At the risk of being
off-topic (and off-Python), I'm including a REBOL script - my only one- that
retrieves a URL, and extracts a particular section from the html.  The
section REBOL[...] is essentially a comment.

-----------------------------------------
REBOL [
 Title: "Zone Forecast Extractor"
 File: %zone.r
 Purpose: {Extract the Virginia Zone Forecast and display it.}
]

zone: read http://iwin.nws.noaa.gov/iwin/va/zone.html

print ""
{parse zone [thru <title> copy result to </title>]
print result}

print "Current Fairfax County Zone Forecast"

fairfax: find zone "Fairfax"
parse fairfax [thru "..." copy forecast to "$$"]

print forecast

</extract>

Notice how easy it is to acquire the html file - it is regarded as a
first-class data type that has content.  No includes or imports needed, all
this machinery is built-in.  Also notice how easy it was to extract the
content of a tag.  This is about all I've done with it, though.  It seems
promising.
