    <p>This is how you can do it. It is not easy and straightforward I'm afraid, though. The way your input XMl is structured makes it harder to access the relevant nodes.</p> <p>For example, in several places you need to access nodes that are naturally not in the context. To adress this I use variables and parameters.</p> <p>But it is quite generic, i.e. you can process an arbitrary number of <code>DATASETS</code>, <code>Regions</code> or <code>Districts</code>. It creates an HTML table to display the counts.</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:output method="xml" indent="yes"/&gt; &lt;xsl:template match="/"&gt; &lt;xsl:element name="html"&gt; &lt;xsl:apply-templates/&gt; &lt;/xsl:element&gt; &lt;/xsl:template&gt; &lt;xsl:template match="DATASETLIST"&gt; &lt;xsl:element name="head"&gt; &lt;xsl:element name="title"&gt; &lt;xsl:text&gt;DATASET counts&lt;/xsl:text&gt; &lt;/xsl:element&gt; &lt;/xsl:element&gt; &lt;xsl:element name="body"&gt; &lt;xsl:element name="table"&gt; &lt;xsl:attribute name="border"&gt;1&lt;/xsl:attribute&gt; &lt;xsl:call-template name="tbl"/&gt; &lt;/xsl:element&gt; &lt;/xsl:element&gt; &lt;/xsl:template&gt; &lt;xsl:template name="tbl"&gt; &lt;xsl:param name="regions" select="distinct-values(DATASET/ROW/Region)"/&gt; &lt;xsl:param name="rows" select="DATASET/ROW"/&gt; &lt;xsl:param name="datasets" select="DATASET"/&gt; &lt;!--header row--&gt; &lt;xsl:element name="tr"&gt; &lt;xsl:element name="th"/&gt; &lt;xsl:for-each select="$datasets"&gt; &lt;xsl:element name="th"&gt; &lt;xsl:value-of select="@entity"/&gt; &lt;/xsl:element&gt; &lt;/xsl:for-each&gt; &lt;/xsl:element&gt; &lt;!--Totals row--&gt; &lt;xsl:element name="tr"&gt; &lt;xsl:element name="td"&gt; &lt;xsl:element name="b"&gt; &lt;xsl:text&gt;Total&lt;/xsl:text&gt; &lt;/xsl:element&gt; &lt;/xsl:element&gt; &lt;xsl:for-each select="$datasets"&gt; &lt;xsl:element name="td"&gt; &lt;xsl:value-of select="count(ROW)"/&gt; &lt;/xsl:element&gt; &lt;/xsl:for-each&gt; &lt;/xsl:element&gt; &lt;xsl:element name="tr"/&gt; &lt;!--region rows--&gt; &lt;xsl:for-each select="$regions"&gt; &lt;xsl:variable name="region" select="."/&gt; &lt;xsl:element name="tr"&gt; &lt;xsl:element name="td"&gt; &lt;xsl:element name="b"&gt; &lt;xsl:value-of select="."/&gt; &lt;/xsl:element&gt; &lt;/xsl:element&gt; &lt;xsl:for-each select="$datasets"&gt; &lt;xsl:element name="td"&gt; &lt;xsl:value-of select="count(ROW/Region[.=$region])"/&gt; &lt;/xsl:element&gt; &lt;/xsl:for-each&gt; &lt;/xsl:element&gt; &lt;!--district rows--&gt; &lt;xsl:for-each select="distinct-values($rows[Region=$region]/District)"&gt; &lt;xsl:variable name="district" select="."/&gt; &lt;xsl:element name="tr"&gt; &lt;xsl:element name="td"&gt; &lt;xsl:value-of select="."/&gt; &lt;/xsl:element&gt; &lt;xsl:for-each select="$datasets"&gt; &lt;xsl:element name="td"&gt; &lt;xsl:value-of select="count(ROW/District[.=$district])"/&gt; &lt;/xsl:element&gt; &lt;/xsl:for-each&gt; &lt;/xsl:element&gt; &lt;/xsl:for-each&gt; &lt;xsl:element name="tr"/&gt; &lt;/xsl:for-each&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre>

    1. COThanks very much for the effort you've put in. Unfortunately I am restricted to XSLT 1.0 so I am attempting to work around the use of distinct-values but you've provided a great starting point.

    2. COYou're welcome. For your future questions you could use the tag `xslt-1.0` to get an answer that is immediately useful to you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
