formatting - PHP simpleXML how to save the file in a formatted way?

Question

I'm trying add some data to an existing XML file using PHP's SimpleXML. The problem is it adds all the data in a single line:

<name>blah</name><class>blah</class><area>blah</area> ...

And so on. All in a single line. How to introduce line breaks?

How do I make it like this?

<name>blah</name>
<class>blah</class>
<area>blah</area>

I am using asXML() function.

Thanks.

You could use the DOMDocument class to reformat your code:

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