设置formatOuput属性重新加载并生成一次

For anyone else who has been having issues with formatOuput not working, here is a work-around:

rather than just doing something like: 

<?php 
$outXML = $xml->saveXML(); 
?> 

force it to reload the XML from scratch, then it will format correctly: 

<?php 
$outXML = $xml->saveXML(); 
$xml = new DOMDocument(); 
$xml->preserveWhiteSpace = false; 
$xml->formatOutput = true; 
$xml->loadXML($outXML); 
$outXML = $xml->saveXML(); 
?>
