SimpleXMLElement返回Empty Object

Question

As simple as the sun light:

$xml = new SimpleXMLElement('<string>-2|-2|635705730515209906|7F2ShUrAQFJmvxTxVgkm2yjghWorOaZe/g==</string>');
             var_dump($xml->{"string"});die();

It prints:

object(SimpleXMLElement)#67 (0) { }

I would expect the content of "string" node... If I do

var_dump($xml);

I get:

object(SimpleXMLElement)#66 (1) { [0]=> string(61) "-2|-2|635705730515209906|7F2ShUrAQFJmvxTxVgkm2yjghWorOaZe/g==" }

But how to get the node "string" ?

Answer 1

The top level element (aka root node) is always implicit. You also need to cast to a scalar type or you'll get the object itself. Combined:

$xml = new SimpleXMLElement('<string>-2|-2|635705730515209906|7F2ShUrAQFJmvxTxVgkm2yjghWorOaZe/g==</string>');
var_dump((string)$xml);
