Question

am trying to pass xml to a rest API am building with cakephp 2.3.0 and am getting an error yet i made it work with cakephp 1.3. Am wondering whether the problem is with the XML core utility of cakephp.

The XML string am posting is as below

<?xml version="1.0" encoding="UTF-8"?>
<username>my username</username>
<password>mypassword</password>
<name>Namanya Hillary</name>
<title>mytitle</title>

And the Error is as below

2013-01-31 07:32:25 Error: [Exception] String could not be parsed as XML
#0 E:\wamp\www\cakephp2.3.0\lib\Cake\Utility\Xml.php(131): SimpleXMLElement->__construct('<?xml version="...', 16384)

I tried passing the XML directly in the core XML utility file in the utility folder as below on line 130

$xml = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?><username>my username</username><password>mypassword</password><name>Namanya Hillary</name><title>mytitle</title>', LIBXML_NOCDATA);

but the same exception is being raised. Please help me if u have encountered such a problem or if u see any mistake made. Reference links to solutions will be useful. Thanks in-advance.

Properly formed XML must have a single root element. You do not have that. Try making the request format something like:

<?xml version="1.0" encoding="UTF-8"?>
<request>
    <username>my username</username>
    <password>mypassword</password>
    <name>Namanya Hillary</name>
    <title>mytitle</title>
</request>
