Gunnar KaysenSubject: replace question

Hi,

I have for example following input string "H&#8595;2&#8595;O" which I need to transform to "H<sub>2</sub>O".

Question for me is
1. How do I match the part that is in between two "&#8595;" (U2193) occurences?
2. How do I enclose this with the <sub/> tag in the output and leave the rest untouched.

Thanks very much for your help!

Here is an idea using XQuery


declare variable $text:= "H&#8595;2&#8595;";

for $token at $p in tokenize($text, "&#8595;")
return
if($p mod 2 = 0) then <sub>{$token}</sub>
else $token
