How can I split a table row in xsl after a specified account?

I have the following xsl that sorts my XML alphabetically:

<xsl:template match="/">
  <xsl:apply-templates />
</xsl:template> 

<xsl:key name="rows-by-title" match="Row" use="translate(substring(@Title,1,1),'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
<xsl:variable name="StartRow" select="string('&lt;tr &gt;')" />

<xsl:template name="Meunchian" match="/dsQueryResponse/Rows">
  <table>
    <tr>
      <xsl:for-each select="Row[count(. | key('rows-by-title', translate(substring(@Title,1,1),'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ'))[1]) = 1]">
        <xsl:sort select="translate(substring(@Title,1,1),'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
        <!-- Puts out the title -->
        <td>
          <xsl:value-of select="translate(substring(@Title,1,1),'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
        </td>
        <!-- Now all it children -->
        <xsl:for-each select="key('rows-by-title', translate(substring(@Title,1,1),'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ'))">
          <xsl:value-of select="@Title" /><br/>
        </xsl:for-each>
      </xsl:for-each>
   </tr>
  </table>
</xsl:template>

XML:

<dsQueryResponse>
  <Rows>
    <Row Title="Agenda" />
    <Row Title="Policy" />
    <Row Title="Policy" />
    <Row Title="Report" />
    <Row Title="Report" />
  </Rows>
</dsQueryResponse>

Now I want to split the table row every 4 columns that are output so that the output looks something like this:

ABCD
EFGH
IJKL
MNOP
QRST
UVWX
YZ

Can anyone suggest a better way to achieve this?

Many thanks

Here is my solution.

You can decide through the options "per-row"and "show-empty"if you want empty cells to be displayed or you need to hide them. I'm sure there is a much more elegant version, but I could not come up with it. ;-) Comments are welcome.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="html" version="4.0" encoding="iso-8859-1" indent="yes"/>

  <xsl:key name="rows-by-title" match="Row" use="translate(substring(@Title, 1, 1), 'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
  <xsl:variable name="alphabet" select="string('ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
  <xsl:variable name="per-row" select="number(4)" /> 
  <xsl:variable name="show-empty" select="false()" />

  <xsl:template match="/">
    <xsl:apply-templates select="dsQueryResponse/Rows" />
  </xsl:template> 

  <xsl:template match="Rows">
    <table>
      <xsl:call-template name="create-rows" />
    </table>
  </xsl:template>

  <xsl:template name="create-rows">
    <xsl:param name="index" select="1" />

    <xsl:variable name="letters">
      <xsl:call-template name="next-letters">
        <xsl:with-param name="index" select="$index" />
      </xsl:call-template>
    </xsl:variable>

    <xsl:if test="$letters != ''">
      <tr title="{$letters}">
        <xsl:call-template name="create-cells">
          <xsl:with-param name="letters" select="$letters" />
        </xsl:call-template>
      </tr>
    </xsl:if>

    <xsl:if test="string-length($letters) = $per-row">
      <xsl:call-template name="create-rows">
        <xsl:with-param name="index" select="string-length(substring-before($alphabet, substring($letters, string-length($letters), 1))) + 2" />
      </xsl:call-template>
    </xsl:if>
  </xsl:template>

  <xsl:template name="next-letters">
    <xsl:param name="index" />

    <xsl:variable name="letter" select="substring($alphabet, $index, 1)" />

    <xsl:variable name="letters">
      <xsl:if test="$index &lt;= string-length($alphabet)">
        <xsl:if test="$show-empty or key('rows-by-title', $letter)">
          <xsl:value-of select="$letter" />
        </xsl:if>

        <xsl:call-template name="next-letters">
          <xsl:with-param name="index" select="$index + 1" />
        </xsl:call-template>
      </xsl:if>
    </xsl:variable>

    <xsl:value-of select="substring($letters, 1, $per-row)" />
  </xsl:template>

  <xsl:template name="create-cells">
    <xsl:param name="letters" />

    <xsl:variable name="letter" select="substring($letters, 1, 1)" />

    <xsl:if test="$letter != ''">
      <td title="{$letter}">
        <strong>
          <xsl:value-of select="$letter" />
        </strong>
        <xsl:apply-templates select="key('rows-by-title', $letter)">
          <xsl:sort select="@Title" />
        </xsl:apply-templates>
      </td>
      <xsl:call-template name="create-cells">
        <xsl:with-param name="letters" select="substring($letters, 2, string-length($letters) - 1)" />
      </xsl:call-template>
    </xsl:if>
  </xsl:template>

  <xsl:template match="Row">
    <br />
    <xsl:value-of select="@Title" />
  </xsl:template>

</xsl:stylesheet>

With this input:

<dsQueryResponse>
  <Rows>
    <Row Title="Agenda" />
    <Row Title="Policy" />
    <Row Title="Policy" />
    <Row Title="Report" />

    <Row Title="Test2" />
    <Row Title="Test1" />
    <Row Title="Boo" />
    <Row Title="Foo" />

I'm a bit confused by the question, but I think you are looking for xsl: if test with a combination of position () and mod
