Create HTML TD cell when node or attribute missing - html

Question

I am working on improving on some stylesheets that I have inherited and converting them from using <xsl:for-each> to <xsl:apply-templates>. A very simplified version of one of the XML files I will be working with is:
<Root>
<Row ID="123" Region="AMS">
<First>Graham</First>
<Last>Smith</Last>
<Sales>12345.85</Sales>
<Team>Team A</Team>
</Row>
<Row id="321">
<First>John</First>
<Last>Brown</Last>
<Sales>18765.85</Sales>
<Team>Team C</Team>
</Row>
<Row id="456" Region="EMEA">
<First>Anne</First>
<Last>Jones</Last>
<Sales>34567.85</Sales>
<Team>Team B</Team>
</Row>
</Root>
The new stylesheet I have is:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html" indent="yes"/>
<xsl:variable name="RowCount" select="count(/*/*)"/>
<xsl:template match="/#* | node()">
<style>
body * {font-family:Arial;font-size:11pt}
table {border-collapse:collapse}
td {border-bottom:1px solid #D8D8D8;padding:7px}
tr.row1 {background:#F9F9F9;}
td.tdHeader {border-bottom:2px solid #DDD;font-weight:700}
</style>
<table>
<thead>
<tr>
<xsl:apply-templates select="*[1]/#*" mode="headerAttributes" />
<xsl:apply-templates select="*[1]/*" mode="headerFields"/>
</tr>
</thead>
<tbody>
<xsl:apply-templates select="*"/>
</tbody>
</table>
</xsl:template>
<xsl:template match="/*/*/#*" mode="headerAttributes">
<td class="tdHeader">
<xsl:value-of select="name()" />
</td>
</xsl:template>
<xsl:template match="/*/*/*" mode="headerFields">
<td class="tdHeader">
<xsl:value-of select="name()" />
</td>
</xsl:template>
<xsl:template match="/*/*">
<tr class="row{position() mod 2}">
<xsl:apply-templates select="#*" mode="attributes"/>
<xsl:apply-templates select="*" mode="fields"/>
</tr>
</xsl:template>
<xsl:template match="/*/*/#*" mode="attributes">
<td>
<xsl:value-of select="." />
</td>
</xsl:template>
<xsl:template match="/*/*/*" mode="fields">
<td>
<xsl:value-of select="." />
</td>
</xsl:template>
</xsl:stylesheet>
but, due to the second node in the XML is missing the <Region> attribute, the cells on the result are mis-aligned, with first name now in the Region column, Last name in First name column and so on. This also happens if there is a missing child node on the Row node. for example, no team element
I have tried to test for a missing node, before calling the apply-template, and within the last two templates, but to no avail.
Any ideas? What am I missing here? I am only just starting to get my head around using apply-templates, but other methods of writing stylesheets I am fine with.

Answer 1

Provisionally, this works for your input:
<xsl:template match="Row">
<tr class="row{position() mod 2}">
<td><xsl:apply-templates select="#ID|#id" mode="attr2"/></td>
<td><xsl:apply-templates select="#Region" mode="attr2"/></td>
<xsl:apply-templates select="*" mode="fields"/>
</tr>
</xsl:template>
<xsl:template match="#ID|#id|#Region" mode="attr2">
<b><xsl:value-of select="." /></b>
</xsl:template>
-- and you may remove the catch-all for mode="attributes".
This forces the inclusion of a <td>..</td> pair even if there is no id|ID or Region attribute.
Saxon 8.8 reports an error:
The attribute axis starting at a document-node() node will never select anything
because of your
<xsl:template match="/#* | node()">
Changing it to <xsl:template match="node()">, or, preferably, to <xsl:template match="Root"> will fix this. As I said in my comment, try to use * as little as possible. References to Root and Row can be changed to exact matches.
