我正在尝试获取xml响应并在响应中提取一个变量并设置为php变量以用于购物车。我有卷曲响应，并使用simplexml。我已经尝试了几种方法将它回显到浏览器并且它们都是空的？
以下是回复和我尝试的内容。
$response = curl_exec($ch);
curl_close($ch);
$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);
$parser = simplexml_load_string((string)$response2);
echo $parser->(string)GetRateQuoteResponse->GetRateQuoteResult->result->Charges->charge[6]->amount;
这是响应转储

XML标记名称区分大小写。
因此，当您导航到特定节点时，请确保也使用正确的标记。
$parser->GetRateQuoteResponse->GetRateQuoteResult->Result->Origin->City;
$parser->GetRateQuoteResponse->GetRateQuoteResult->Result->Charges
->Charge[6]->Amount;
