Yes, you would need to define a variable containing all the tokens (same as you
would in xsl:for-each).
Alternatively you could "look-behind" by setting an extra parameter $previous
as you move through the list.

Hi All,
This is related to my previous question about a line-break algorithm. In my
tokenized list, I want to "look-ahead" to the next member of the list. I
tried .[position()+1] but this doesn't work. Do I need to set the
tokenize($input) to a variable first? Thank you.
