Which bit isn't working exactly? The only thing that might be causing issue is the use of . in your very final expression. You could try replacing it with current(). I can never remember when to use which, since there are subtle differences between the two.
Anyway, I copied your XML into a Symphony Static Data Source and got this XSLT working.
<xsl:template match="/">
<xsl:apply-templates select="//page-layout/record[type='data-list']" mode="table"/>
</xsl:template>
<xsl:template match="record" mode="table">
<table>
<thead>
<xsl:apply-templates select="content/headers/record" mode="header"/>
</thead>
<tbody>
<xsl:apply-templates select="content/data/record" mode="row"/>
</tbody>
</table>
</xsl:template>
<xsl:template match="record" mode="header">
<th><xsl:apply-templates select="name"/></th>
</xsl:template>
<xsl:template match="record" mode="row">
<xsl:variable name="row-data" select="."/>
<tr>
<xsl:for-each select="//content/headers/record/column">
<td><xsl:value-of select="$row-data/*[name()=current()]"/></td>
</xsl:for-each>
</tr>
</xsl:template>
I simplified things somewhat by recognising patterns in the original XML. Each table, header and body row are record nodes, so the templates to create each of these matches simply on a record. A mode is passed to each to ensure the correct one is used. I'm starting to use this approach more often — make matched templates very generic using modes, but make the apply-templates calling them very specific. This way, the more generic templates can be re-used (e.g. you can re-use the heading template anywhere else providing you have a record node in your XML).

Thanks Nick,
I knew this was the right place to come, the secret key was current(), I too mix the two and with all of the things I've been working on today I just couldn't get passed that brick wall. This works wonders, and your idea with the modes simplifies things immensely! Thanks Tons!

No worries, glad it's sorted.
A couple of references I have bookmarked but always fail to return to:

This is not directly related to symphony but this is one of the better venues for finding XSL help that I know of. To start with I have some XML that looks like this:
<page-layout> <record> <type>data-list</type> <name>users</name> <content> <headers> <record> <name>ID</name> <column>id</column> </record> <record> <name>Name</name> <column>name</column> </record> </headers> <data> <record> <id>1</id> <name>nick</name> <pass>xxx</pass> <salt>xxx</salt> <auto_pass>xxx</auto_pass> </record> </data> </content> <settings/> </record> </page-layout>and what I am wanting to do is use the
//page-layout/*/content/headers/*/columnto designate how to create my table of data. Right now there is only one record in the//page-layout/*/content/datanode set but the idea is to have all the data for thatdata-listin that node set.right now my xsl looks like this:
<xsl:template match="page-layout/*[type='data-list']"> <table class="tablemain" cellspacing="0" cellpadding="0"> <thead> <xsl:apply-templates select="content/headers" /> </thead> <tr> <xsl:apply-templates select="content/data"> <xsl:with-param name="columns" select="//content/headers/*/column" /> </xsl:apply-templates> </tr> </table> </xsl:template> <xsl:template match="page-layout/*[type='data-list']/content/headers/record"> <th><xsl:apply-templates select="name" /></th> </xsl:template> <xsl:template match="page-layout/*[type='data-list']/content/data/record"> <xsl:param name="columns" /> <xsl:variable name="data" select="." /> <tr> <xsl:for-each select="$columns"> <td><xsl:value-of select="." /><xsl:text> ( </xsl:text><xsl:value-of select="name()" /><xsl:text> ) </xsl:text><xsl:text>:</xsl:text><xsl:value-of select="$data/*[name(.) = .]" /></td> </xsl:for-each> </tr> </xsl:template>The last template is what I'm having issues with. Any help would be appreciated :)
