Hi All I have a bizzar issue which is driving me nuts. I was running a php server on my pc to test my code with no issues - now moved it to the host server and get this issue when try to parse xml: Warning: simplexml_load_string() [function.simplexml-load-string]: Entity: line 1: parser error : Start tag expected, '<' not found in /websites/123reg/LinuxPackage22/tr/ad/in/tradingbay.co/public_html/Lib/Functions.php on line 154 here is my code:

$TDurl = "http://api.tradedoubler.com".$Version.$module.$Format.$TDParams.$Token;print $TDurl;$TDResponse = @file_get_contents($TDurl);$TDParsed_Xml = simplexml_load_string($TDResponse);

i have compared the $TDResponse between my test pc and the web host and both look identical - therefore am still puzzled why one works and not the other. could be something to do with the xml header? <?xml version="1.0"?> i have similar xml structures which are correctly parsed (using the same technic) but have a slightly different xml header?xml version="1.0" encoding="UTF-8"?>

The sample you're showing from TDResponse doesn't look at all like XML, it's not a surprise that the parser doesn't like it. Actually, it sounds like you're not looking at its actual value. Use htmlspecialchars() to see its real content:

echo htmlspecialchars($TDResponse);

Here is the first time where the problem starts:

< updateDate>1353600101304</updateDate>

You can see the start tag starts with a space. That's not a valid XML. Whoever is in charge of generating the XML at api.tradedoubler.com needs to fix that, and you should contact them.It's possible that it previously worked on your PC server either because the point where problem with the other end was introduced, coincides with your migration OR (more likely) because your PC server's XML parser was different from your host one, and your PC one somehow recovered from that error.
