    copied!<p>I'm a newbie and I'm trying to use test in an &lt;xsl:when&gt; element to see if the current node is a descendant of an earlier node. I then want to apply the appropriate html tag to the content. I am a novice with xpath expressions.</p> <p>Specifically, I would like to apply &lt;th&gt; tags to the &lt;tcell&gt; elements that are descendants of the &lt;thead&gt; element. I would like to apply &lt;td&gt; tags to the &lt;tcell&gt; elements that are descendants of the &lt;tbody&gt; elements. My best guess is that I have to use an &lt;xsl:choose&gt; element in my &lt;xsl:template match="tcell"&gt; element. I have tried a few different xpath expressions in the test, but none of them have worked.</p> <p><strong>Question:</strong> Is &lt;xsl:choose&gt; the best option for this?</p> <p>Here is my xml document, the applicable part. The document structure cannot be changed.</p> <pre><code>&lt;table&gt; &lt;tgroup&gt; &lt;thead&gt; &lt;trow&gt; &lt;tcell&gt;Column Head Text&lt;/tcell&gt; &lt;tcell&gt;Column Head Text&lt;/tcell&gt; &lt;/trow&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;trow&gt; &lt;tcell&gt;Cell Text&lt;/tcell&gt; &lt;tcell&gt;Cell Text&lt;/tcell&gt; &lt;/trow&gt; &lt;/tbody&gt; &lt;/tgroup&gt; &lt;/table&gt; </code></pre> <p>I want to use XSL/XPath to generate a table with a header row and body rows. My XSL stylesheet looks like this:</p> <pre><code>&lt;xsl:template match="/"&gt; &lt;html&gt; &lt;body&gt; &lt;xsl:apply templates /&gt; &lt;/body&gt; &lt;/html&gt; &lt;/xsl:template&gt; &lt;xsl:template match="table"&gt; &lt;table&gt; &lt;xsl:apply-templates /&gt; &lt;/table&gt; &lt;/xsl:template&gt; &lt;xsl:template match="tgroup"&gt; &lt;xsl:apply-templates/&gt; &lt;/xsl:template&gt; &lt;xsl:template match="thead"&gt; &lt;thead&gt; &lt;xsl:apply-templates /&gt; &lt;/thead&gt; &lt;/xsl:template&gt; &lt;xsl:template match="tbody"&gt; &lt;tbody&gt; &lt;xsl:apply-templates /&gt; &lt;/tbody&gt; &lt;/xsl:template&gt; &lt;xsl:template match="trow"&gt; &lt;tr&gt; &lt;xsl:apply-templates /&gt; &lt;/tr&gt; &lt;/xsl:template&gt; &lt;!-- MY TROUBLE STARTS HERE --&gt; &lt;xsl:template match="tcell"&gt; &lt;xsl:choose&gt; &lt;xsl:when test="current()!=descendant::tbody"&gt; &lt;th&gt; &lt;xsl:value-of select="."/&gt; &lt;/th&gt; &lt;/xsl:when&gt; &lt;xsl:otherwise&gt; &lt;td&gt; &lt;xsl:value-of select="."/&gt; &lt;/td&gt; &lt;/xsl:otherwise&gt; &lt;/xsl:choose&gt; &lt;/xsl:template&gt; </code></pre> <p>Any help would be appreciated.</p> <p><strong>Sample html output</strong></p> <pre><code>&lt;table&gt; &lt;tgroup&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;Column Head Text&lt;/th&gt; &lt;th&gt;Column Head Text&lt;/th&gt; &lt;tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;Cell Text&lt;/td&gt; &lt;td&gt;Cell Text&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/tgroup&gt; &lt;/table&gt; </code></pre> <p>Thanks, M_66</p>
