include param in mod evaluation

mlaba · October 11th, 2004, 07:53 AM

I want to set the column count I use to build a html table within my xsl at the top of the style sheet. So, I need to change the '4' in the following line of code to '$colCount'

<xsl:template match="child::node()[(position()-1) mod 4 = 0]" >

What is the proper syntax for this call? Would I create the colCount as a variable or param?

Create it as an variable..
Proper synatx is
match = match="child::node()[(position()-1) mod $colCount = 0]"

You would normally use a param if you wanted to set it before running the stylesheet using the processor dependent method.
In MSXML for example you would use the addParameter method.

Here is a shortened version of my stlye sheet.

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:msxsl="urn:schemas-microsoft-com:xslt"
  xmlns:local="myLocal">

        <xsl:output method="html" indent="yes" />

       <xsl:param name="columnCount">4</xsl:param>

      <xsl:template match="/" >
        <html>
        <xsl:if test="count($nodes)> 0">

            <table border="0" width="100%">
                <xsl:apply-templates select="nodes/*"/>
            </table>

        </xsl:if>
        </html>
    </xsl:template>

      <xsl:template match="child::node()[(position()-1) mod $columnCount = 0]" > </xsl:template>

      <xsl:template match="child::node()[(position()-1) mod 4 != 0]" /> </xsl:template>

      <xsl:template name="format">

      </xsl:template>

</xsl:stylesheet>

I can't seem to get the $columnCount param to be recognized?????

Hi,

You cannot use variables (or params) in a match expression.

To help you further, can you supply some example xml and explain the result you expect.

First it may be worth looking at the Faq section on the following site under grouping.

Using the style sheet above I want to be able to change the value of "columnCount" at the top of the style sheet and there by set the number of columns displayed in my html table. The format of the xml is irrelevant I believe. hmmm...so changing the 4 to a variable is not possible in a match statement. Does that mean I'll need to somehow perform this calculation within a JS function and return the value to some sort of variable or sumthin. Wow, this is deep stuff. I think I like it :-)
