Subject: Re: Is there a Ruby library that does HTML entity parsing?

Steve, I've been using the URI lib quite a bit, but it doesn't parse entities. One feature that would be nice to add is one that calculates the URL for the directory that contains a document, given its complete URL.
 
For example, consider:
 
http://www.foo.com/bar/something.htm
 
This document clearly lives in
 
http://www.foo.com/bar/
 
This is required if you want to resolve document-relative URL links as in:
 
<a href="otherpage.htm">...
 
which would send you to:
 
http://www.foo.com/bar/otherpage.htm
 
I've hacked this thing in for my own code, which was my first foray into ranges etc:
 
def getDocumentRelativeUri(documentUri, uri_str)
  doc = documentUri.to_s
  return CGI.unescapeHTML(doc[0..doc.rindex('/')] + uri_str)
end

John,

If you haven't yet, check out the URI lib that ships with ruby.  It's
pretty hot $%@*.   Not sure if handles QSV's though.  Maybe you could
tell me?  :)
