copied!<p>SimpleXML doesn't support that kind of manipulation. Currently, it can only append children. To insert children at arbitrary places in the tree, you need <a href="http://docs.php.net/manual/en/book.dom.php" rel="nofollow noreferrer">DOM</a> and <a href="http://docs.php.net/manual/en/domnode.insertbefore.php" rel="nofollow noreferrer">DOMNode::insertBefore()</a> specifically. The problem is that DOM is verbose and it makes it annoying to use, that's why when I have to do that kind of things, I use a mixture of SimpleXML and DOM. The result became a library aptly named <a href="http://code.google.com/p/simpledom/" rel="nofollow noreferrer">SimpleDOM: use DOM methods with SimpleXML grammar</a>.</p> <p>Also, here's a few tips that I recommend as good practice:</p> <ul> <li>Whenever you create a SimpleXMLElement object, name it after the node it represents. Never name it <code>$xml</code>. "XML" is a markup language, it's text. If I'd see an <code>$xml</code> var I'd think it contains text.</li> <li>The same applies to your <code>$xml_toload</code> var. It doesn't contain XML, it contains a filepath. Therefore, it should be named something like <code>$filepath</code>.</li> <li>You don't have to use <code>addAttribute()</code> or <code>addChild()</code> for everything. It's often simpler to use the array notation and/or the object notation.</li> </ul> <p>The result script:</p> <pre><code>include 'SimpleDOM.php'; // create an <image/> element $image = new SimpleXMLElement('<image/>'); $image['imageURL'] = $file; $image['thumbURL'] = $file; $image['linkURL'] = $linkurl; $image['linkTarget'] = $linkurl; $image->caption = $caption; // load the file $path_to_file = $_SERVER['DOCUMENT_ROOT']. '/xml/'.$country.'/compact.xml'; $imagegallery = simpledom_load_file($path_to_file); // insert the new element before the first <image/> $imagegallery->insertBefore($image, $imagegallery->image[0]); // save the file $imagegallery->asXML($path_to_file); </code></pre>
