Not like this, but it can be done. XSLT 1.0 sees the entire attribute value 
as a string, which (unlike a node set) you can't iterate over using for-each.

Use a named template which calls itself recursively, chopping up the string 
as it goes. You'll want to use the substring-before() function or its 
equivalent. Examples of this can be found in the FAQ or the list archives: 
search for "tokenizing a string" or such like. Or Mike K. gives you an 
extension function to tokenize in Saxon (saxon:tokenize(), I think), if 
you're using that.

XSLT 2 will be more powerful for such tasks as these.

Good luck (and let us know if you're stumped looking for that solution),
Wendell
