    <p>I have a problem an at the moment no idea to solve it ;-(</p> <p>I have a category structure as input document (xml) and want to build a path structure. I can only use xslt and want to generate a new xml structure.</p> <p>The input structure looks like this:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;Positions&gt; &lt;Positionen&gt; &lt;ID&gt;1&lt;/ID&gt; &lt;Parent&gt;&lt;/Parent&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;2&lt;/ID&gt; &lt;Parent&gt;1&lt;/Parent&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;3&lt;/ID&gt; &lt;Parent&gt;1&lt;/Parent&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;4&lt;/ID&gt; &lt;Parent&gt;2&lt;/Parent&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;5&lt;/ID&gt; &lt;Parent&gt;4&lt;/Parent&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;6&lt;/ID&gt; &lt;Parent&gt;2&lt;/Parent&gt; &lt;/Positionen&gt; &lt;/Positions&gt; </code></pre> <p>The output structure should be this:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;Positions&gt; &lt;Positionen&gt; &lt;ID&gt;1&lt;/ID&gt; &lt;Parent&gt;&lt;/Parent&gt; &lt;Path&gt;1&lt;/Path&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;2&lt;/ID&gt; &lt;Parent&gt;1&lt;/Parent&gt; &lt;Path&gt;1/2&lt;/Path&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;3&lt;/ID&gt; &lt;Parent&gt;1&lt;/Parent&gt; &lt;Path&gt;1/3&lt;/Path&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;4&lt;/ID&gt; &lt;Parent&gt;2&lt;/Parent&gt; &lt;Path&gt;1/2/4&lt;/Path&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;5&lt;/ID&gt; &lt;Parent&gt;4&lt;/Parent&gt; &lt;Path&gt;1/2/4/5&lt;/Path&gt; &lt;/Positionen&gt; &lt;Positionen&gt; &lt;ID&gt;6&lt;/ID&gt; &lt;Parent&gt;2&lt;/Parent&gt; &lt;Path&gt;1/2/6&lt;/Path&gt; &lt;/Positionen&gt; &lt;/Positions&gt; </code></pre> <p>How can I do this with xslt with a recursion? Hoping fore some help. Thanks in advance. LStrike</p>

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).
