Hi,
Is there a method or any library which allows me to unescape encoded
html. For example If I have hi%5Bthere%5D
I should get hi[there]

I believe you’re looking for the CGI::unescape method. If for some
reason you don’t have that, you can do a simple gsub like this, though
it can fail in many ways and only handles hex entities.
gsub(/%([[:xdigit:]]{2})/) {|c| $1.hex.chr }

encoded HTML ? what you will need is hpricot (which is amazing 
require ‘rubygems’
require ‘hpricot’
Hpricot(“hi>there<”, :xhtml_strict => true).to_plain_text # =>
“hi>there<”
But! from your example seems like you don’t want to unescape html but
the url:
require ‘cgi’
CGI.unescape “hi%5Bthere%5D”
=> “hi[there]”
Greets!

I think you mean encoded URL, not encoded HTML. For URL encoding, you
can use URL.unescape, or CGI.unescape as Michael sugests.
HTML escaping is a bit more complex, but the CGI has some methods,
e.g. CGI.escapeHTML/CGI.unescapeHTML.
Thanks for the replies , actually I want to unescape some form
parameters which contain [ and ] .
The CGI.unescape works…Is it a superset of what URL.unescape does?
