With XPath 2.0, what is the easiest way to split a string into a sequence of strings of length one e.g. "Kibology" into ("K", "i", "b", "o", "l", "o", "g", "y") I came up with e.g. for $index in 1 to string-length("Kibology") return substring("Kibology", $index, 1) but wonder whether there is a shorter/easier way.

Not sure about 'easier', let alone 'faster' (I'm sure it isn't), but it is 40% shorter, to ~48 chars (choose the token wisely):

tokenize(replace('Kibology', '(.)', '$1~'), '~')

Wannabe sure of the token not being in your string, use Private Use Area characters:

tokenize(replace('Kibology', '(.)', '$1'), '')

but this doubtlessly makes it less readable and a bit larger ;)
