WebLinkListExample in RubyLanguage using RegularExpression matching (because I'm not aware of anything in the standard library for parsing HTML):

 #!/usr/bin/env ruby
 
 require 'net/http'
 require 'uri'
 
 # usage:   linklister.rb url
 # example: linklister.rb h''''''ttp://www.google.com/
 
 url = ARGV[0] ? ARGV[0] : 'h''''''ttp://www.google.com/'
 parsed_url = URI.parse url
 page = Net::HTTP.get parsed_url.host, parsed_url.path
 
 nested_hrefs = page.scan /href\s*=\s*\"([^\"]*)|href\s*=\s*\'([^\']*)|href\s*=\s*([^\s\"\'>]+)/i
 
 puts "*** hrefs in #{url} ***"
 nested_hrefs.flatten.each do |href|
     puts href if href
 end

Output on 2005-12-30:

 *** hrefs in h''''''ttp://www.google.com/ ***
