RE: MOD Every Other easy - but what about every 3rd

2005-01-21 00:55:31
You seem to have been using "mod" without realising how it works.

you want

position() mod 3 = 0
position() mod 3 = 1
position() mod 3 = 2

to characterize the three possible renditions.

Using MOD to determine odd rows is easy.  However, I'd like to have 3
alternating rows so need to recognize the 1st row, the 2nd row, the
3rd and start over.
So:

..blue row..
..red row..
..green row..
..blue row..
....and so on....

This didn't work:
<xsl:choose>
  <xsl:when test="position() mod 3 = 
0">background_blue_fade</xsl:when>
  <xsl:when test="position() mod 2 = 
0">background_green_fade</xsl:when>
  <xsl:otherwise>background_red_fade</xsl:otherwise>
</xsl:choose>
