    <p><strong>I. This simple and efficient XSLT 1.0 transformation (no variables and no post-processing of results):</strong></p> <pre><code>&lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:output omit-xml-declaration="yes" indent="yes"/&gt; &lt;xsl:strip-space elements="*"/&gt; &lt;xsl:template match="/*"&gt; &lt;Year&gt; &lt;xsl:apply-templates/&gt; &lt;/Year&gt; &lt;/xsl:template&gt; &lt;xsl:template match="Movies"&gt; &lt;MovieList&gt; &lt;xsl:apply-templates/&gt; &lt;/MovieList&gt; &lt;/xsl:template&gt; &lt;xsl:template match="Add"&gt; &lt;xsl:value-of select="substring('*,', 2 - (position()=1),1)"/&gt; &lt;xsl:value-of select="concat(Key, '-', Value)"/&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p><strong>when applied on the provided XML document:</strong></p> <pre><code>&lt;Year&gt; &lt;Movies&gt; &lt;Add&gt; &lt;Key&gt;movie1&lt;/Key&gt; &lt;Value&gt;black&lt;/Value&gt; &lt;/Add&gt; &lt;Add&gt; &lt;Key&gt;movie2&lt;/Key&gt; &lt;Value&gt;white&lt;/Value&gt; &lt;/Add&gt; &lt;/Movies&gt; &lt;/Year&gt; </code></pre> <p><strong>produces the wanted, correct result:</strong></p> <pre><code>&lt;Year&gt; &lt;MovieList&gt;*movie1-black,movie2-white&lt;/MovieList&gt; &lt;/Year&gt; </code></pre> <hr> <p><strong>II. XSLT 2.0 Solution:</strong></p> <pre><code>&lt;xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:output omit-xml-declaration="yes" indent="yes"/&gt; &lt;xsl:strip-space elements="*"/&gt; &lt;xsl:template match="/*"&gt; &lt;Year&gt; &lt;xsl:apply-templates/&gt; &lt;/Year&gt; &lt;/xsl:template&gt; &lt;xsl:template match="Movies"&gt; &lt;MovieList&gt; &lt;xsl:sequence select="'*'[current()/Add]"/&gt; &lt;xsl:value-of select="Add/concat(Key, '-', Value)" separator=","/&gt; &lt;/MovieList&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre>

    1. COThanks, Dimitre. The 1.0 transformation was nice and clean. Much better than the direction I was headed.

    2. CO@MikeLemke: You are welcome. Using many, simple templates with proper match patterns is one of the most distinctive XSLT design pattern and it results in simple, extensible and reliable code.

    3. COLeveraging implicit type conversion from a boolean to a number is very clever. I liked that ;)

Querying!

 
Guidance
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).
