Recursion is one of the most fundamental properties of functional languages, 
XSLT including.

Try to find available examples of recursive processing in XSLT. In your 
solution you'll also need the XPath substring() function.

The way to think of the problem is as follows:

  1. Stop condition -- when the string is empty.

  2. Process the first character of the string (use substring())

  3. Solve the same problem on the remaining string. You can get the 
remaining string again with substring().

Apart from this, FXSL has a convenient str-foldl() function/template. It 
implements any char by char string processing.
