I am not sure what technology you are trying to use. This is the Mozilla
newsgroup for XML. tokenize is a function supported in XPath and XSLT
2.0 and in XQuery 1.0 but as far as I know Mozilla does only support
XSLT and XPath 1.0 which does not know any sequences.

In XPath 2.0 to access the second item in the sequence $foo is simply
   $foo[2]
so
   tokenize('in the beginning', ' ')[2]
should give you the string 'the'.
