note 92051 added to function.simplexml-element-asXML

Using the method posted by administrator at proxy-list dot org I have extended the SimpleXMLElement class to output 'pretty' XML automagically. <?php class SimpleXMLPretty extends SimpleXMLElement { public function asXML($filename = null) { $doc = new DOMDocument('1.0'); $doc->preserveWhiteSpace = false; $doc->loadXML(parent::asXML()); $doc->formatOutput = true; $xml = new parent($doc->saveXML()); if (!$filename) { return $xml->asXML(); } else { return $xml->asXML($filename); } } } // Example usage: $xml = new SimpleXMLPretty($xmlstr); echo $xml->asXML(); // output pretty xml $xml->asXML('foo.xml'); // saving as a file works too ?> Comments are appreciated. Should the function be declared as static? Is there a better way to handle the file save feature? ---- Server IP: 209.41.74.194 Probable Submitter: 69.19.14.17 (proxied: 72.168.228.129) ---- Manual Page -- http://www.php.net/manual/en/function.simplexml-element-asXML.php Edit -- https://master.php.net/note/edit/92051 Del: integrated -- https://master.php.net/note/delete/92051/integrated Del: useless -- https://master.php.net/note/delete/92051/useless Del: bad code -- https://master.php.net/note/delete/92051/bad+code Del: spam -- https://master.php.net/note/delete/92051/spam Del: non-english -- https://master.php.net/note/delete/92051/non-english Del: in docs -- https://master.php.net/note/delete/92051/in+docs Del: other reasons-- https://master.php.net/note/delete/92051 Reject -- https://master.php.net/note/reject/92051 Search -- https://master.php.net/manage/user-notes.php
