Format output of $SimpleXML->asXML(); [duplicate]

There's a variety of solutions in the comments on the PHP manual page for SimpleXMLElement. Not very efficient, but certainly terse, is a solution by Anonymous

$dom = dom_import_simplexml($simpleXml)->ownerDocument;$dom->formatOutput = true;echo $dom->saveXML();

The PHP manual page comments are often good sources for common needs, as long as you filter out the patently wrong stuff first.

The above didn't work for me, I found this worked:

$dom = new DOMDocument("1.0");$dom->preserveWhiteSpace = false;$dom->formatOutput = true;$dom->loadXML($simpleXml->asXML());echo $dom->saveXML();

Found a similar solution...to format raw xlm data..from my php SOAP requests __getLastRequest & __getLastResponse, for quick debugging the xml's i have combined it with google-code-prettify.

Its a good solution if you want to format sensitive xml data and don't want to do it online.

Some sample code below, may be helpful to others:

$dom = new DOMDocument;$dom->preserveWhiteSpace = false;$dom->formatOutput = true;$dom->loadXML($data); //=====$data has the raw xml data...you want to formatecho '<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js"></script>';echo "<br/> <pre class=\"prettyprint\" >". htmlentities($dom->saveXML())."</pre>";

Below is a sample of the Formatted XML Output I got:

Note: The formatted XML is available in $dom->saveXML() and can be directly saved to a xml file using php file write.
