    <p>I'm using eXist for a project at work, and I've run into a problem that I can't seem to figure out a solution for.</p> <p>I have an xquery script that is updating an existing document that is already in the database. Part of the data that needs to be updated contains HTML, specifically <code>&lt;p&gt;</code> and <code>&lt;/p&gt;</code> tags. I cannot get eXist/XQuery to stop escaping the HTML. It <em>needs</em> to be preserved in it's original form. Here's a very simple version of what I'm doing:</p> <pre><code>&lt;pre&gt; declare variable $raw-content := request:get-parameter('content', '') declare variable $content := local:clean($raw-content) &lt;/pre&gt; </code></pre> <p><code>local:clean</code> is the following function:</p> <pre><code>&lt;pre&gt; declare function local:clean($text) { let $text := util:parse($text) return $text }; &lt;/pre&gt; </code></pre> <p>Later on in the code I update a specific XML element</p> <pre><code>&lt;pre&gt; {update replace $n/sports-content/article/nitf/body/body.content with &lt;body.content&gt;{$content}&lt;/body.content&gt;} &lt;/pre&gt; </code></pre> <p>Now, this works perfect <em>if</em> I only pass in data wrapped in one set of tags (ie <code>&lt;p&gt;foo&lt;/p&gt;</code>). If I do <code>&lt;p&gt;foo&lt;/p&gt;&lt;p&gt;bar&lt;/p&gt;</code>, I get a null value placed in <code>$text</code>.</p> <p>I've been banging my head against the desk for a day and a half now trying to figure out why this doesn't work. Any help in solving this problem would be greatly appreciated.</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.
