error php domDocument xml parsing

Question

Does anybody know how I can get this xml into the domDocument?

Right now, it throws an error saying it is missing a top level element. What I see is that feed is the toplevel element, so it's a mystery to me. This only happens if I run it threw the domDocument and not when I echo it out directly. The xml validator also gives no errors.

This is the xml:

$xml="<?xml version='1.0' encoding='UTF-8'?><feed xmlns='http://www.w3.org/2005/Atom' xmlns:gphoto='http://schemas.google.com/photos/2007' xmlns:openSearch='http://a9.com/-/spec/opensearch/1.1/'

this does not work

@$dom = new DOMDocument();      
$dom_xml = $dom->loadXML($xml); 
$output= $dom_xml->saveXML(); 
echo $output;

thanks in adv, Richard

I can't reproduce the problem. Can you please make it a tested, self-contained example script? — VolkerK

hmm, how exactly, originally, I gave the output variable to the view object and disable the layout in the mvc. I can put this code on top off the indexfile instead, that way I will be sure that only this code is run. — Richard

The best way to load from a string is to use the loadXML function.

$dom->loadXML($xml); doesn't return an object when called in an object context (i.e. $obj->loadxml()) but modifies the internal state of the object itself.

e.g.

$doc = new DOMDocument();      
$doc->loadXML($xml) or die('loadxml failed');
$output= $doc->saveXML(); 
echo phpversion(), "\n";
echo '|savexml|=', strlen($output), "\n";
echo '|children| = ', $doc->documentElement->childNodes->length, "\n";

prints (on my machine)

5.3.1
|savexml|=5840
|children| = 33

thanks, if this is the solution Is it not possible then to echo the output again and see the rss feed page. All I get is an error with the top level el missing?

Richard Over a year ago

actually, I can see the same output as you. IE was caching, so I opend another browser window. Thanks for helping me out. I only have this question left. If I run it threw the domDocument without making alterations. Can I get the same xml back, because if I set a header to xml. The output will cause errors?

Richard Over a year ago

I can see the output with the header set to text/plain I consider this question closed. Thanks VolkerK. Time for me to struggle a bit further.

Why not just use file_put_contents ? like this

file_put_contents("myxml.xml",$xml);
