Subject: Re: Help for extracting text with regexp.

You know what they say, if you choose to use a regex you've got
another problem :(

How about this?

a = "foo.bar/somePath/somepage.php?attr=value&theone=64646hs554&other=ddd"

a.split(/\?|&/).each do |b|
  if b =~ /^theone=(.*)/
    puts $1
  end
end
