Hi All,

The title pretty much says it all.

If I have something like (from the php site examples):

 $xmlstr = <<<XML
<?xml version='1.0' standalone='yes'?>
<movies></movies>
XML;

$sxe = new SimpleXMLElement($xmlstr);

$sxe->addAttribute('type', 'documentary');

$movie = $sxe->addChild('movie');
$movie->addChild('title', 'PHP2: More Parser Stories');
$movie->addChild('plot', 'This is all about the people who make it work.');

$characters = $movie->addChild('characters');
$character  = $characters->addChild('character');
$character->addChild('name', 'Mr. Parser');
$character->addChild('actor', 'John Doe');

$rating = $movie->addChild('rating', '5');
$rating->addAttribute('type', 'stars');


echo("<pre>".htmlspecialchars($sxe->asXML())."</pre>");

die();

I end up outputing a long string like so:

<?xml version="1.0" standalone="yes"?>
<movies type="documentary"><movie><title>PHP2: More Parser Stories</title><plot>This is all about the people who make it work.</plot><characters><character><name>Mr. Parser</name><actor>John Doe</actor></character></characters><rating type="stars">5</rating></movie></movies>

This is fine for a program consumer, but for debugging/human tasks, does anyone know how to get this into a nice indented format?

Answer 1

Will this help? It's an XML pretty-printer regexp.

Google also has one.

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.
