    <p>I'm trying to write a greasemonkey script for a rather unpleasantly structured page. I'd like to be able to show and hide different entries, but they're in the form:</p> <pre><code>&lt;a name="first"/&gt; &lt;h3&gt;First&lt;/h3&gt; Some text.... &lt;!-- end --&gt; &lt;a name="second"/&gt; &lt;h3&gt;Second&lt;/h3&gt; Some text.... &lt;!-- end --&gt; </code></pre> <p>I was hoping to be able to wrap these in &lt;div&gt;s, e.g.:</p> <pre><code>&lt;a name="first"/&gt; &lt;div name="first&gt; &lt;h3&gt;First&lt;/h3&gt; Some text.... &lt;!-- end --&gt; &lt;/div&gt; </code></pre> <p>How can I do this? I was thinking of using the prev ~ siblings jQuery selector, then iterating through until I reach another matching , but then (a) I have to match the next manually, and (b) I'm not sure how then to put them inside the when that's done?</p> <p>Thanks!</p> <p>PS. Why did I have to use &amp;lt; and &amp;gt; to write &lt;div&gt; instead of angle braces?</p> <p><strong>UPDATE:</strong></p> <p>So far, I have:</p> <pre><code>$(document).ready(function(){ var course = $("meta[name=DEPARTMENT]").attr("content").replace(/^\s+/, ""); $("a[name^="+course+".]:first").each(function(){ GM_log(this.name); var stop=false; $(this).nextAll().filter(function(){ if ($(this).is("a[name^="+course+".]")) { stop=true; } return !stop; }) .wrapAll(document.createElement("div")); }); }); </code></pre> <p>However, this leaves the orphaned text behind:</p> <pre><code>&lt;a name="first"/&gt; &lt;div name="first&gt; &lt;h3&gt;First&lt;/h3&gt; &lt;!-- end --&gt; &lt;/div&gt; Some text... </code></pre> <p><strong>UPDATE 2:</strong> It turns out that the nextAll function is written to only return element nodes. I wrote a replacement:</p> <pre><code>$.fn.nextAllWithText = function() { var ret = []; $(this).each(function() { var cur = this.nextSibling; while (cur &amp;&amp; cur != document) { ret.push(cur); cur = cur.nextSibling; }; }); return $(ret); }; </code></pre>

    1. CO"PS. Why did I have to use &lt; and &gt; to write <div> instead of angle braces?" because stackoverflow allows inline html markup such as <br/> in posts, but not in comments ;-)

    2. COOK, thanks! I'd always thought they went for pure markdown.

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).
