我正在尝试通过

节点进行循环。

我在正确的线路上，回答如下：

$fedex_xml = simplexml_load_string($fedex_response);

$RateReply = $fedex_xml->children("env", true)->Body->children("v13", true)->RateReply;
foreach($RateReply->RateReplyDetails as $details){

}

$fedex_xml = simplexml_load_string($fedex_response);

$RateReply = $fedex_xml->children("env", true)->Body->children("v13", true)->RateReply;
foreach($RateReply->RateReplyDetails as $details){

}
