DOM返回空对象

Question

This is my code:

<?php
$content = utf8_encode( file_get_contents( "data.xml") );
$XML = new DOMDocument();
$XML->loadXML($content);

echo "<pre>" . print_r($XML, 1) . "</pre>";
?>

It does return:

 DOMDocument Object
(
)

I've read its a bug or something, since both var_dump and print_r or any will return an empty object element.

http://www.php.net/manual/en/class.domelement.php#86224

This guy gave an solution to better use:

$xml = $XML->saveXML($XML);
echo "<pre>" . print_r($xml, 1) . "</pre>";

But then, when I'm reloading the page, it looks like there are only spaces, because I can't see anything, but I can select it...

Where is the problem, have you guys any solutions for that?

Answer 1

A var_dump on DOMDocument always returns an empty object.

Illustration:

$xml = simplexml_load_file('test.xml'); //load your xml

var_dump($xml); //var_dump via SimpleXML (lot of data)

$doc = new DOMDocument(); //fire up domdocument

$xmlstring = $xml->asXML(); //convert SimpleXML to string

$doc->loadXML($xmlstring);  //loads perfectly 

var_dump($doc); //empty object

Maybe you should consider SimpleXML?
