Therefore I post here a save function.

function simpledom_save_file(&$simpleDom, $filepath = null) { $dom = new DOMDocument('1.0'); $dom->preserveWhiteSpace = false; $dom->formatOutput = true; $dom->loadXML ($simpleDom->asXML()); $result = $dom->saveXML ();

if (isset($filepath)) { return (bool) file_put_contents($filepath, $result); }

return $result; }

Actually, this method already exists. SimpleXML offers the asXML() method, to which you can pass a filepath if you want the output to be saved. SimpleDOM offers the asPrettyXML() method, which does an equivalent job except that the output is indented with libxml's "formatOuput" option as in your example. Enjoy!

$node = new SimpleDOM('<root><child1><grandchild1 /></child1><child2 /><child3 /></root>');
// if you want to see the result
echo $node->asPrettyXML();
// if you want to save the result
$node->asPrettyXML('/tmp/result.xml');

Yes, I know. I know also that you need the XSLT processor up and running. This is not standard in my php config from xampp.
