copied!<p>While <a href="http://de.php.net/manual/en/book.simplexml.php" rel="nofollow noreferrer">SimpleXML</a> provides <a href="https://stackoverflow.com/a/16062633/367456">a way to remove</a> XML nodes, its modification capabilities are somewhat limited. One other solution is to resort to using the <a href="http://de.php.net/manual/en/book.dom.php" rel="nofollow noreferrer">DOM</a> extension. <a href="http://de.php.net/manual/en/function.dom-import-simplexml.php" rel="nofollow noreferrer">dom_import_simplexml()</a> will help you with converting your <code>SimpleXMLElement</code> into a <code>DOMElement</code>.</p> <p>Just some example code (tested with PHP 5.2.5):</p> <pre><code>$data='<data> <seg id="A1"/> <seg id="A5"/> <seg id="A12"/> <seg id="A29"/> <seg id="A30"/> </data>'; $doc=new SimpleXMLElement($data); foreach($doc->seg as $seg) { if($seg['id'] == 'A12') { $dom=dom_import_simplexml($seg); $dom->parentNode->removeChild($dom); } } echo $doc->asXml(); </code></pre> <p>outputs</p> <pre><code><?xml version="1.0"?> <data><seg id="A1"/><seg id="A5"/><seg id="A29"/><seg id="A30"/></data> </code></pre> <p>By the way: selecting specific nodes is much more simple when you use XPath (<a href="http://de.php.net/manual/en/function.simplexml-element-xpath.php" rel="nofollow noreferrer">SimpleXMLElement->xpath</a>): </p> <pre><code>$segs=$doc->xpath('//seq[@id="A12"]'); if (count($segs)>=1) { $seg=$segs[0]; } // same deletion procedure as above </code></pre>
