RE: FW: Siblings

This is working, but had to resort to an XSL:CHOOSE, the modulo value (which
would result in 0) kept throwing me off.  Any ideas how to avoid the
XSL:CHOOSE and stick with pure mathematics?

<!-- next event can not result in value 0 -->
<xsl:variable name="next_event">
  <xsl:choose>
  <xsl:when test="((position() + $event_offset) mod ($event_count + 1)) =
0">
    <xsl:value-of select="((position() + $event_offset) mod ($event_count +
1)) + 1" />
  </xsl:when>
  <xsl:otherwise>
    <xsl:value-of select="(position() + $event_offset) mod ($event_count +
1)" />
  </xsl:otherwise>
  </xsl:choose>
</xsl:variable>

<!-- here is the sample xml -->
  <EVENT_TYPE type="ARTM">
    <EVENT olympic_order="1" display="Floor">1</EVENT>
    <EVENT olympic_order="2" display="Pommel">2</EVENT>
    <EVENT olympic_order="3" display="Rings">3</EVENT>
    <EVENT olympic_order="4" display="Vault">4</EVENT>
    <EVENT olympic_order="5" display="PBars">5</EVENT>
    <EVENT olympic_order="6" display="HiBar">6</EVENT>
    <EVENT olympic_order="7" display="AA">AA</EVENT>
  </EVENT_TYPE>

Hi Karl,

Use the following :-
<xsl:value-of select="elements/element[@item = ($offset mod
count(/elements/element)+1) ]" />

Cheers.
