Development PHP/XML: new DOM Nodes inside rss Nodes don't format properly

If I use the PHP DOM object to append a new child before or after my rss element it formats perfectly.

If I instead put the new DOM Node inside the rss tag (as though I wanted to add it as my most recent item... go figure) then it loses all formating and stays on one line...

Example of it inserted inside RSS tag:

Code:

<?xml version="1.0" encoding="UTF-8"?> 
<rss xmlns:atom="http://www.w3.org/2005/Atom" xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> 
<item><title>some title</title><author>OneSeventeen</author></item>
</rss>
 

Example of the same thing inserted outside the RSS tag:

Code:

<?xml version="1.0" encoding="UTF-8"?> 
<rss xmlns:atom="http://www.w3.org/2005/Atom" xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> 
</rss>
<item>
    <title>some title</title>
    <author>OneSeventeen</author>
</item>
</item>
 

BIG UPDATE:
I added a tag around the rss tag, and had the same poor formatting problem! (even with the new node inserted outside the rss tag but inside my new "foo" tag)

New theory: adding a node inside an XML item loaded from a file makes formatting teh suck by default.

now if I pass LIBXML_NOBLANKS as the $options argument of DOMDocument::load($file, $options) then it formats the whole document (including my new stuff) properly.

 

Also, I read an awesome tip on the PHP manual for formatOutput:

PHP:

$xml = new DOMDocument::load('somefile.xml');
$xml->formatOutput = true;
//do a bunch of manipulation

//now pass the supposedly (but not really) formatted output to a variable:
$outXML = $xml->saveXML(); //I'm a crappily formated XML feed, boo hoo

//now create a brand new XML document
$xml = new DOMDocument(); 
$xml->preserveWhiteSpace = false; 
$xml->formatOutput = true; //yup, going to try to make this format again
//pass the output of the first bunch of stuff we did to the new XML document:
$xml->loadXML($outXML); 
//now display the cleanly formatted output without using LIBXML_NOBLANKS (which may have undesired consequences
print $xml->saveXML();
