<p>I'm looking for the pseudoclass <code>:has</code> in <a href="http://nokogiri.org/Nokogiri/XML/Node.html" rel="nofollow">Nokogiri</a>. It should work just like jQuery's <a href="http://api.jquery.com/has-selector/" rel="nofollow"><code>has</code> selector</a>.</p> <p>For example:</p> <pre><code><li><h1><a href="dfd">ex1</a></h1><span class="string">sdfsdf</span></li> <li><h1><a href="dsfsdf">ex2</a></h1><span class="string"></span></li> <li><h1><a href="sdfd">ex3</a></h1></li> </code></pre> <p>The CSS selector should return only the first link, the one with the not-empty <code>span.string</code> sibling.</p> <p>In jQuery this selector works well:</p> <pre><code>$('li:has(span.string:not(:empty))>h1>a') </code></pre> <p>but not in Nokogiri:</p> <pre><code>Nokogiri::HTML(html_source).css('li:has(span.string:not(:empty))>h1>a') </code></pre> <p><code>:not</code> and <code>:empty</code> works well, but not <code>:has</code>.</p> <hr> <ol> <li>Is there any documentation for CSS selectors in Nokogiri?</li> <li>Maybe someone can write a custom <code>:has</code> pseudo class? Here is an <a href="http://nokogiri.org/Nokogiri/XML/Node.html#method-i-css" rel="nofollow">example</a> how to write a <code>:regexp</code> selector.</li> <li>Optionally I can use XPath. How do I write XPath for <code>li:has(span.string:not(:empty))>h1>a</code>?</li> </ol>

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.
