    <p><strong>Update: Xpath version of <code>*[@class~='my-class']</code> css selector</strong></p> <p>So after my comment below in response to hakre's comment, I got curious and looked into the code behind <code>Zend_Dom_Query</code>. It looks like the above selector is compiled to the following xpath (untested):</p> <p><code>[contains(concat(' ', normalize-space(@class), ' '), ' my-class ')]</code></p> <p>so the php would be:</p> <pre><code>$dom = new DomDocument(); $dom-&gt;load($filePath); $finder = new DomXPath($dom); $classname="my-class"; $nodes = $finder-&gt;query("//*[contains(concat(' ', normalize-space(@class), ' '), ' $classname ')]"); </code></pre> <p>Basically, all we do here is normalize the <code>class</code> attribute so that even a single class is bounded by spaces, and the complete class list is bounded in spaces. Then append the class we are searching for with a space. This way we are effectively looking for and find only instances of <code>my-class</code>.</p> <hr> <p>Use an xpath selector?</p> <pre><code>$dom = new DomDocument(); $dom-&gt;load($filePath); $finder = new DomXPath($dom); $classname="my-class"; $nodes = $finder-&gt;query("//*[contains(@class, '$classname')]"); </code></pre> <p>If it is only ever one type of element you can replace the <code>*</code> with the particular tagname.</p> <p>If you need to do alot of this with very complex selector i would recommend <a href="http://framework.zend.com/manual/en/zend.dom.query.html" rel="noreferrer"><code>Zend_Dom_Query</code></a> which supports CSS selector syntax (a la jQuery):</p> <pre><code>$finder = new Zend_Dom_Query($html); $classname = 'my-class'; $nodes = $finder-&gt;query("*[class~=\"$classname\"]"); </code></pre>

    1. COfinds the class `my-class2` as well, but pretty sweet. Any way to only pick the first of all elements?

    2. COI dont think you can without xpath2... However the example for Zend_Dom_Query does exactly that. IF you dont want to use that compkenet in your project then you might want to see how they are translating that css selector to xpath. Maybe DomXPath supports xpath 2.0 - im not sure about that.

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.
