Re: Alternating Odd and Even with a twist

I want to alternate rows between a odd and even class
in my CSS. The twist is that If there is no
information in the tag I don't want to print and I
want to maintain my odd and even structure. The html
would look like this
<class="rowodd">Hi</class>
<class="roweven">How are you?</class>
<class="rowodd">Bye</class>
xml:
<item1>Hi</item1>
<item2>How are you?</item2>
<item3>Bye</item3>
but say there was no information where How are you?
I want it to go:
<class="rowodd">Hi</class>
<class="roweven">Bye</class>
xml:
<item1>Hi</item1>
<item3>Bye</item3>
I can get the text not to print, but how do I assign
the classes?

I hope your elements are *not* named item1, item2, item3...
But if you really want:
 <xsl:for-each select="*[substring(name(),1,4)='item']">
   <class>
     <xsl:choose>
       <xsl:when test="position() mod 2 = 0">
          <xsl:attribute name="name">even</xsl:attribute>
       </xsl:when>
       <xsl:otherwise>
          <xsl:attribute name="name">odd</xsl:attribute>
       </xsl:otherwise>
     </xsl:choose>
     <xsl:apply-templates/>
   </class>
 </xsl:for-each>
