PHP - Parsing XML object created by simplexml_load_string()

Question

I am trying to read an attribute value of the root node of an XML fed into the simplexml_load_string() method in PHP.

Here is an example,

<user status="Active">
</user>

I am trying to read the value of 'status' in the above XML string.

--- Here is an update ---

Below is the XML Structure,

<data status="Active">
 <user> <userid> 1 </userid> </user>
 <user> <userid> 2 </userid> </user>
<data>

The statements below dont work too.. var_dump() outputs "NULL" echo (string)$xml -> user[0] -> userid; echo (string)$xml->attributes()->status

Could some1 lead me on this ?

Regards, Immanuel

Answer 1

echo (string)$userNode->attributes()->status should work

Answer 2

$xml = simplexml_load_string('<user status="Active"></user>');

echo $xml->attributes()->status;

Answer 3

Besides the attributes() method you can simply access the element's attributes by treating the element object like an array (SimpleXMLElement implements ArrayAccess)

$xml = simplexml_load_string('<user status="Active"></user>');
echo 'status=', $xml['status'];

But to access attributes in other namespaces you have to use attributes() (afaik).

Thanks for the replies... Parsing was not really the problem.

I missed the following cURL parameters,

curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");

I was treating a boolean value (cURL response) as an XML file :)

Thanks all...
