Ruby unescape HTML string

Any idea how I can unescape the following string in Ruby?

C&#x3a;&#x5c;inetpub&#x5c;wwwroot&#x5c;adminWeb

C:\inetpub\wwwroot\adminWeb

or to

C%3A%5Cinetpub%5Cwwwroot%5CadminWeb

Tried with URI.decode with no success.

An alternative is using the standard lib's URI module:

require 'uri'
URI.unescape "C%3A%5Cinetpub%5Cwwwroot%5CadminWeb" # => "C:\\inetpub\\wwwroot\\adminWeb"

EDIT This is answer is obsolete. Please check this thread.

One more variant is HTMLEntities

HTMLEntities.new.decode "C&#x3a;&#x5c;inetpub&#x5c;wwwroot&#x5c;adminWeb"             
# => "C:\\inetpub\\wwwroot\\adminWeb"

I prefer to use it because it deals with rare cases aså and — which CGI.unescapeHTML does not

The CGI library is one option:

require 'cgi'

CGI.unescapeHTML('C&#x3a;&#x5c;inetpub&#x5c;wwwroot&#x5c;adminWeb')
# => "C:\\inetpub\\wwwroot\\adminWeb"
