As Michael said you should be able to write that in a tail recursive
style, which your processor should be able to use without using up the
stack.
But yu can also write it without recursion at all I think.
<xsl:variable name="items" select="tokenize($originaltext,' ')"/>
then the maximum length is
<xsl:vvariable name="max" select="max($items/string-length(.))"/>
and an item of that length is
$items[strring-length(.)=$max][1]
