RE: Problem With Different Colors for Alternate Rows

Jeorg,

Thank you. Mode seems to be working ok, except for one thing -- in my
real XSLT (which is more complicated than the sample below), for certain
data elements (e.g., side dish) I search for multiple occurences of the
element and I concatenate them with commas as below. This is causing
confusion in the assessment of the position() function. It seems to
think I am looking for the position of the row, when I am really looking
for the position of this particular side dish. This confusion is causing
each side dish to print out on a new line instead of on a single line
with a comma-separated list. Is there any way to test if this side dish
is first or last w/o using the position() function (thus avoiding this
type of confusion)?

<xsl:template match="Side_Dish">
<xsl:if test="position() = 1">
	<xsl:text disable-output-escaping="yes">&lt;td
class="oddRowStyle"&gt;Side Dish:&lt;td
class="oddRowStyle"&gt;</xsl:text>
</xsl:if>
      <xsl:value-of select="."/>
<xsl:choose>
	<xsl:when test="position() != last()">
 		<xsl:text>, </xsl:text>
	</xsl:when>
	<xsl:otherwise>
		<xsl:text
disable-output-escaping="yes">&lt;/td&gt;</xsl:text>
	</xsl:otherwise>
</xsl:choose>
</xsl:template>

Thanks,
Rechell Schwartz

Hello Rechell,

there is also a simple XSL way:

<xsl:template match="/Food_List">
   <table>
     <xsl:apply-templates select="Main_Food_List | Side_Dish | Desert" 
mode="row"/>
   </table>
</xsl:template>

<xsl:template match="*" mode="row">
   <TR class="evenRowStyle">
     <xsl:if test="position() mod 2 = 1">
       <xsl:attribute name="class">oddRowStyle</xsl:attribute>
     </xsl:if>
     <xsl:apply-templates select="."/>
   </TR>
</xsl:template>

<xsl:template match="Main_Food_List">
   <TD>Main Course:</TD>
   <TD><xsl:value-of select="Main_Course"/></TD>
</xsl:template>

<xsl:template match="Side_Dish">
   <TD>Side Dish:</TD>
   <TD><xsl:value-of select="."/></TD>
</xsl:template>

<xsl:template match="Desert">
   <TD>Desert:</TD>
   <TD><xsl:value-of select="Fancy_Desert"/></TD>
</xsl:template>

Regards,

Joerg

return the result set as a list of HTML rows in alternating colors.All
of the examples that I have seen address how to do this if every data
row is is derived from the same type of XML tag. But in my example, each
row may come from a completely different section of the XML. Following
is a sample XML similar to the one that I am using. Also, another
constraint is if any row is missing, it is inhibited, and the
alternating color rule must still be preserved. I have tried numerous
ways of passing parameters, but have been unable to modify the the row
count after a match was found ofr each item. Any help would be GREATLY
appreciated.
