Steve,
At 01:32 PM 9/28/2007, you wrote:
you don't say if teh input is known to be sorted, if it is (in xslt 1
or 2)
/answers/option[last()]/@p
if the input is not known to be in the right order then (in xpath 2)
max(/answers/option/@p)
And again, there's a fancy workaround in XSLT 1.0:
<xsl:for-each select="$nodes">
<xsl:sort select="sort"/>
<xsl:if test="position()=1">...</xsl:if>
</xsl:for-each>
... which is squirrely, but then that comes with the territory of 1.0.
This trick is written up in several places. Someone thought of it in
the old days of XSLT 1.0, as an alternative to a recursive template
call (whew).
Cheers,
Wendell
