Does anyone have a way to change the background color of every other row in a table with xsl-fo. I'm using nFOP to create pdf's and have accomplished most everything I've needed but would like to have say every other row have a light gray background. If I statically set the rows of the table this would be easy, but my rows are generated with an <xsl-for each> as I do not know ahead of time how many results I'll have in my xml.

Is there a way to tell how many rows end up in the table and then apply formating, or say apply conditional formatting to odd or even numbered rows?

Thanks in advance.

It's hard to tell without looking at what you're input and desired output are, but you can do this pretty easily. Make use of the position() function to determine what number position in the ancestry the node you're processing. Once you do that, you choose to apply one template for odds and one template for evens. Each one would do the exact same thing except change the color of the row.

That's a pretty simple thing to do. Create a variable called "evenOdd" and have it be even if the position() of the loop modulus 2 is equal to 0. If not, have it be odd. Let's say you have a calendar XML file with the following format (where the dots represent the values):

<root>
   <calendar>
      <event>
          ...
      </event>
      <event>
          ...
      </event>
      <event>
          ...
      </event>
      <event>
          ...
      </event>
      <event>
          ...
      </event>
   </calender>
</root>

To display the event data, you'll run an xsl:for-each loop where you'll output the <div> and the value inside of it (event), but you'll also create an attribute (class) that will determine whether the outputted div (for each event) is a even or odd.

<xsl:for-each select="/data/calendar">
   <div><xsl:value-of select="event"></div>

<xsl:attribute name="class">
   <xsl:choose>
      <xsl:when test="position() mod 2 = 0">
         <xsl:text>even</xsl:text>
      </xsl:when>
      <xsl:otherwise>
         <xsl:text>odd</xsl:text>
      </xsl:otherwise>
   </xsl:choose>
</xsl:attribute>

</xsl:for-each>

Hope that helped. If not, feel free to PM me and I'll go into greater detail or attempt helping you in any way you need help.
