Hi Folks,
I have a variable that contains a bunch of numbers:
<xsl:variable name="numbers">
generate some numbers
</xsl:variable>
I want to obtain the last number in $numbers.
For example, this might be the value of $numbers:
6 23 45 67
I want the last number:
67
I want the last number fast, i.e., I want it in constant time, not O(n), where
n is the length of the list of numbers.
Plus, I don't want to use any extension functions/elements.
Finally, I want to use only XSLT 1.0
Can it be done? How?
/Roger
