    <p>I need to match all 'tags' (e.g. %thisIsATag%) that occur within XML attributes. (Note: I'm guaranteed to receive valid XML, so there is no need to use full DOM traversal). My regex is working, except when there are <strong>two</strong> tags in a single attribute, only the last one is returned.</p> <p>In other words, this regex should find tag1, tag2, ..., tag6. However, it omits tag2 and tag5.</p> <p>Here's a fun little test harness for you (PHP):</p> <pre><code>&lt;?php $xml = &lt;&lt;&lt;XML &lt;data&gt; &lt;slideshow width="625" height="250"&gt; &lt;screen delay="%tag1%"&gt; &lt;text x="30%" y="50%" animatefromx="800"&gt; &lt;line fontsize="32" fontstyle="bold" text="Screen One!%tag2% %tag3%"/&gt; &lt;/text&gt; &lt;/screen&gt; &lt;screen delay='%tag4%'&gt; &lt;text x="30%" y="50%" animatefromx="800"&gt; &lt;line fontsize='32' fontstyle='bold' text='Screen 2!%tag5%%tag6%'/&gt; &lt;/text&gt; &lt;/screen&gt; &lt;screen&gt; &lt;text x="30%" y="50%" animatefromx="800"&gt; &lt;line fontsize="32" fontstyle="bold" text="Screen Tres!"/&gt; &lt;/text&gt; &lt;/screen&gt; &lt;screen&gt; &lt;text x="30%" y="50%" animatefromx="800"&gt; &lt;line fontsize="32" fontstyle="bold" text="Screen FOURRRR!"/&gt; &lt;/text&gt; &lt;/screen&gt; &lt;/slideshow&gt; &lt;/data&gt; XML; $matches = null; preg_match_all('#&lt;[^&gt;]+("([^%&gt;"]*%([^%&gt;"]+)%[^%&gt;"]*)+"|\'([^%&gt;\']*%([^%&gt;\']+)%[^%&gt;\']*)+\')[^&gt;]*&gt;#i', $xml, $matches); print_r($matches); ?&gt; </code></pre> <p>Thanks! :)</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.
