    <p>I have the following XML:</p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt; &lt;entries&gt; &lt;entry&gt; &lt;title&gt;Entry 1&lt;/title&gt; &lt;prices&gt; &lt;price&gt;10&lt;/price&gt; &lt;price&gt;50&lt;/price&gt; &lt;/prices&gt; &lt;/entry&gt; &lt;entry&gt; &lt;title&gt;Entry 2&lt;/title&gt; &lt;prices&gt; &lt;price&gt;200&lt;/price&gt; &lt;price&gt;300&lt;/price&gt; &lt;/prices&gt; &lt;/entry&gt; &lt;entry&gt; &lt;title&gt;Entry 3&lt;/title&gt; &lt;prices&gt; &lt;price&gt;70&lt;/price&gt; &lt;price&gt;500&lt;/price&gt; &lt;/prices&gt; &lt;/entry&gt; &lt;/entries&gt; </code></pre> <p>Each element has more than one price tag, I want to select the MAX price, per element and use it for comparison with the rest of the elements.</p> <p>My xslt is:</p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt; &lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:template match="/"&gt; &lt;html&gt; &lt;body&gt; &lt;table border="1"&gt; &lt;tr&gt; &lt;th&gt;Title&lt;/th&gt; &lt;th&gt;Highest Price&lt;/th&gt; &lt;/tr&gt; &lt;xsl:for-each select="entries/entry"&gt; &lt;xsl:sort select="prices/price" order="descending" data-type="number"/&gt; &lt;tr&gt; &lt;td&gt;&lt;xsl:value-of select="title"/&gt;&lt;/td&gt; &lt;td&gt;&lt;xsl:value-of select="prices/price"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/xsl:for-each&gt; &lt;/table&gt; &lt;/body&gt; &lt;/html&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p>It doesn't work. It produces:</p> <pre><code>Title Highest Price Entry 2 200 Entry 3 70 Entry 1 10 </code></pre> <p>While it should produce:</p> <pre><code>Title Highest Price Entry 3 500 Entry 2 300 Entry 1 50 </code></pre> <p>Please advise me. I have to use XSLT1, so I can't really do:</p> <pre><code>&lt;xsl:sort select="max(prices/price)" order="descending" data-type="number"/&gt; </code></pre> <p>...</p>

    1. COHow can you have "30" in the output but it is not even in the source XML. Please edit your source XML so it could fit your expected output. Best regards, Peter

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).
