    <p>I am trying to edit an XML document using PHP, but it does not seem to work, wonder where I am going wrong!</p> <p>I am trying to do it the following way which I found online. Can anyone please show me the right direction?</p> <p><strong>XML</strong></p> <pre><code>&lt;gold&gt; &lt;coin&gt; &lt;id&gt;1&lt;/id&gt; &lt;title&gt;Gold Coin 50 Grams&lt;/title&gt; &lt;price&gt;500 rupees&lt;/price&gt; &lt;dimension&gt;20 MM&lt;/dimension&gt; &lt;thumb_url&gt;http://animsinc.com/Expertise-media.png&lt;/thumb_url&gt; &lt;/coin&gt; &lt;coin&gt; &lt;id&gt;2&lt;/id&gt; &lt;title&gt;Gold Coin 50 Grams&lt;/title&gt; &lt;price&gt;500 rupees&lt;/price&gt; &lt;dimension&gt;20 MM&lt;/dimension&gt; &lt;thumb_url&gt; http://animsinc.com/Expertise-media.png&lt;/thumb_url&gt; &lt;/coin&gt; ... &lt;/gold&gt; </code></pre> <p><strong>PHP Code</strong></p> <pre><code>$xmlDoc = new DOMDocument(); $xmlDoc-&gt;loadXml($str); $events = $xmlDoc-&gt;getElementsByTagName("coin"); foreach($events as $event){ $eventNames = $event-&gt;getElementsByTagName("price"); $eventN = $eventNames-&gt;item(0)-&gt;nodeValue; if('500' == $eventN){ // ** Failed here, instead of '500', // I used '500 rupees' and it worked, as that matches the original text.** $eventNames-&gt;item(0)-&gt;nodeValue = $rest ; } } var_dump($xmlDoc-&gt;saveXML()); </code></pre> <p>Here's the desired result. Notice how I've changed the price tag to 2495 rupees. </p> <pre><code> &lt;gold&gt; &lt;coin&gt; &lt;id&gt;1&lt;/id&gt; &lt;title&gt;Gold Coin 50 Grams&lt;/title&gt; &lt;price&gt;2495 rupees&lt;/price&gt; &lt;dimension&gt;20 MM&lt;/dimension&gt; &lt;thumb_url&gt;http://animsinc.com/Expertise-media.png&lt;/thumb_url&gt; &lt;/coin&gt; &lt;coin&gt; &lt;id&gt;2&lt;/id&gt; &lt;title&gt;Gold Coin 50 Grams&lt;/title&gt; &lt;price&gt;2495 rupees&lt;/price&gt; &lt;dimension&gt;20 MM&lt;/dimension&gt; &lt;thumb_url&gt; http://animsinc.com/Expertise-media.png&lt;/thumb_url&gt; &lt;/coin&gt; ... &lt;/gold&gt; </code></pre>

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).
