Subject: Double characters in string

Hi,

I'm looking for a way to put a 'X' between all double characters in a
string. So if this would be the string: 'hello, I just said hello' would
be changed into 'helXlo, I just said helXlo'.

I tried:

text = text.sub(/([a-z])\1/,'\1x\1')

But this only changed the first double character...

Thanks in advance
