RE: [xsl] variable change in xsl:for-each

["Jason Macki" <jmacki@xxxxxxx>]

Hi Markus,

You can't update the content of a variable with XSLT.

In order to alternate the colour of your cell, use the position() and
mod() functions to determine if the current position is odd or even.

For example, this XML:

<rows>
  <item>one</item>
  <item>two</item>
  <item>three</item>
</rows>

...used against this XSLT:

<xsl:for-each select="rows/item">
	<xsl:choose>
		<xsl:when test="(position() mod 2) = 0">Even</xsl:when>
		<xsl:otherwise>Odd</xsl:otherwise>
	</xsl:choose>
	<br />
</xsl:for-each>

..will produce the following result:

Odd
Even
Odd

If you haven't heard of mod() before, a mod b returns the number of
times b can be subtracted from a without returning a negative result.

Subject: [xsl] variable change in xsl:for-each


Hello,

I want the background to change in each cell. But in every cell I only
get the #FFFFFF-background. I think the variable isn't updated in the
choose-procedure. But I don't know why.  Hope you can help.

Thanks!
Markus

Sorry!!! I forget the subject in last mail. So I posted again

heres my xsl-file:

<xsl:variable name="xrowcolor" select="false()"/>
<xsl:variable name="rowcolor">#FFFFFF</xsl:variable>
<xsl:for-each select="//meldungen">
   <xsl:choose>
     <xsl:when test="$xrowcolor">
       <xsl:variable name="rowcolor">#FFFFFF</xsl:variable>
       <xsl:variable name="xrowcolor" select="false()"/>
     </xsl:when>
     <xsl:otherwise>
       <xsl:variable name="rowcolor">#FFFF11</xsl:variable>
       <xsl:variable name="xrowcolor" select="true()"/>
     </xsl:otherwise>
   </xsl:choose>
   <fo:table-cell>
      <fo:block background-color="{$rowcolor}" font-weight="bold">
        <xsl:value-of select="eingang"/>
      </fo:block>
   </fo:table-cell>
</fo:for-each>
