如何解析从SoapClient命令返回的Std类对象到XML

How to Parse a return of a Std Class object from a SoapClient command into a XML

SoapClient命令的响应返回它:

stdClass Object
(
    [ExecutarXMLResult] => stdClass Object
    (
        [any] => <i9proerp xmlns=""><listatomador id_pessoa="5251" nm_pessoa="nome1" nr_cnpj_cpf="1"/><listatomador id_pessoa="939" nm_pessoa="nome2" nr_cnpj_cpf="2"/><listatomador id_pessoa="3285" nm_pessoa="nome3" nr_cnpj_cpf="3"/></i9proerp>
     )
 )

我如何得到返回到XML?

$obj = ... // result from soap, as stated above
$obj->ExecutarXMLResult->any (XML string)

是否是一个有效的XML字符串，这不是我们讨论的一部分。
