Hi:

I have a problem using xsl variable.  I'm trying to create a table for
product comparison.  There will be 2-4 products to compare.  You don't
know there are 2 ro 3 or 4.  It depends on XML, so the table column is
dynamic.

The problem is I'm trying to append a variable $xmltag.  It doesn't
interpret as I want.  I have tried my ways using +, quote, [].

<xsl:copy-of select="content[1]/$xmltag"/>

If anyone knows how to do it, please help.


----------------This is my xslt file-----------------

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html"/>

<xsl:template match="xml" xml:space="preserve">


	<a href="#">RETURN TO LIST</a>


	<table cellpadding="0" cellspacing="0" width="100%" border="1">
		<tr>
			<td>Model</td>
			<td>first</td>
			<td>second</td>
			<xsl:if test="count(content) &gt;= 3"><td>third</td></xsl:if>
			<xsl:if test="count(content) = 4"><td>forth</td></xsl:if>
		</tr>
		<xsl:call-template name="createRow">
			<xsl:with-param name="xmlname">Avarage Price</xsl:with-param>
			<xsl:with-param name="xmltag">AveragePrice</xsl:with-param>
		</xsl:call-template>

	</table>
</xsl:template>

<xsl:template name="createRow">
	<xsl:param name="xmlname"/>
	<xsl:param name="xmltag"/>

	<tr>

select="content[3]/$xmltag"/></td></xsl:if>
		<xsl:if test="count(content) = 4"><td><xsl:value-of
