无法从XML加载字符串（SimpleXML）

Question

I use PHP function simplexml_load_string and trying to get Data from XML Data But it look like i cannot get anything from this xml data

SimpleXMLElement Object ( [attribute] => Array ( [0] => SimpleXMLElement Object ( [name] => uname [value] => admin ) [1] => SimpleXMLElement Object ( [name] => playerlevel [value] => 1 ) [2] => SimpleXMLElement Object ( [name] => sessionid [value] => i9vfgvqo30c2kk2g57avmd0t ) ) )

This is my code

$xml = simplexml_load_string($request->body);

I have try with echo $xml[0], $xml[0]->value, $xml[1], It cannot get anything from this xml data.

It's easier to derive the correct call from the XML rather than a print_r() from the SimpleXMLObject (which makes heavy use of Iterator and ArrayAccess)

If the (reverse engineered) XML is something along

<root>
    <attribute>
        <name>uname</name>
        <value>admin</value>
    </attribute>
    <attribute>
        <name>playerlevel</name>
        <value>1</value>
    </attribute>
    <attribute>
        <name>sessionid</name>
        <value>i9vfgvqo30c2kk2g57avmd0t</value>
    </attribute>
</root>

then the call sequence for the first <root><attribute><name> is

$xml->attribute[0]->name
