RE: Different Colors for Alternating Rows

Jarno,

Thank you. The second approach did not work. It seemd to create an endless 
loop. Here is the error that I got, which repeated endlessly:

at weblogic.apache.xalan.templates.ElemChoose.execute(ElemChoose.java:152)
        at 
weblogic.apache.xalan.templates.ElemForEach.transformSelectedNodes(ElemForEach.java:498)
        at 
weblogic.apache.xalan.templates.ElemApplyTemplates.execute(ElemApplyTemplates.java:193)
        at 
weblogic.apache.xalan.transformer.TransformerImpl.executeChildTemplates(TransformerImpl.java:2208)

Hi,

For one, you can simplify your stylesheet by rewriting this to

  <xsl:template match="tr[td[not(a or @class)]]">
    <xsl:copy>
      <xsl:variable name="x">
        <xsl:choose>
          <xsl:when test="count(preceding-sibling::tr[td[not(a or @class)]]) 
mod 2 = 1">evenMedium</xsl:when>
          <xsl:otherwise>oddMedium</xsl:otherwise>
        </xsl:choose>
      </xsl:variable>
      <xsl:for-each select="td[1]">
        <td class="{$x}" width="35%">
          <xsl:apply-templates select="node()|@*"/>
        </td>
      </xsl:for-each>
      <xsl:for-each select="td[2]">
        <td class="{$x}" width="65%">
          <xsl:apply-templates select="node()|@*"/>
        </td>
      </xsl:for-each>
    </xsl:copy>
  </xsl:template>

But a recursive solution could be something like

  <xsl:template match="node()|@*" name="copy">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="table">
    <xsl:copy>
      <xsl:apply-templates select="@*|tr[1]"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="tr">
    <xsl:param name="odd" select="true()"/>
    <xsl:choose>
      <xsl:when test="td[not(a or @class)]">
        <xsl:variable name="x">
          <xsl:choose>
            <xsl:when test="$odd">odd</xsl:when>
            <xsl:otherwise>even</xsl:otherwise>
          </xsl:choose>
          <xsl:text>Medium</xsl:text>
        </xsl:variable>
        <xsl:for-each select="td[1]">
          <td class="{$x}" width="35%">
            <xsl:apply-templates select="node()|@*"/>
          </td>
        </xsl:for-each>
        <xsl:for-each select="td[2]">
          <td class="{$x}" width="65%">
            <xsl:apply-templates select="node()|@*"/>
          </td>
        </xsl:for-each>
        <xsl:apply-templates select="following-sibling::tr[1]">
          <xsl:with-param name="odd" select="not($odd)"/>
        </xsl:apply-templates>
      </xsl:when>
      <xsl:otherwise>
        <xsl:call-template name="copy"/>
        <xsl:apply-templates select="following-sibling::tr[1]">
          <xsl:with-param name="odd" select="$odd"/>
        </xsl:apply-templates>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
