All the type-coercion functions take single operands, not sequences, so I'm pretty sure that is the simplest way to do it in XPath 2.0. In XPath 3.0, you can use the "simple map operator", !, to write codepoints-to-string(tokenize($numbers/Numbers,'\p{Zs}')!xs:integer(.)) Whether you think that's simpler might be a matter of taste, though. -- Graydon
