Subject: gsub with match replacement

I'm trying to convert

"12&#58;34" => "12:34"

(I know there is a CGI module with unescapeHTML(), I'm working in a
ruby environment that does not allow for additions of modules)

I'm trying:

    "12&#58;34".gsub(/&#(\d+);/,'\1'.to_i.chr)

But I get "1234"

Can anyone explain what I'm doing wrong?

BTW I know I can do:

    "12&#58;34".gsub(/&#(\d+);/) do
	Integer($1).chr
    end

but for some reason in the ruby environment I'm working in
I get 'Undefined method Integer for main:Object'
