Question

我正在尝试使用php访问xml的节点值。但我无法访问其中任何一个。但是，网址正在返回响应。我正在使用cURL发送帖子请求。

我的代码看起来像

     $url = (some url);
  $postDatas = 'CompanyCode=' . urlencode($companyCode) . '&ServiceCode=' . urlencode($serviceCode) . '&Account=' .urlencode($account) . '&Special1=' .urlencode($special1) . '&Special2=' .urlencode($special2) . '&ExternalDate=' .urlencode($externalDate) . '&ExternalId=' .urlencode($externalId) . '&SalesPointType=' .urlencode($salesPointType) . '&UserName=' .urlencode($userName) . '&UserPassword=' .urlencode($userPassword);
                        $ch = curl_init( $url );
                        curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
                        curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
                        curl_setopt( $ch, CURLOPT_POST, 1);
                        curl_setopt( $ch, CURLOPT_POSTFIELDS, $postDatas);
                        curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
                        curl_setopt( $ch, CURLOPT_HEADER, 0);
                        curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
                        $response = curl_exec( $ch );
                        curl_close ($ch);
                        print_r($response);

在执行print_r（$ response）时，我得到了这样的xml响应。

  <PPResponse Type="Check" Key="182f55a7-ed3f-e511-940e-005056b219f6" Result="000" OperationId="61289766243683">
      <ResultMessage>Operation was successfully completed.</ResultMessage>
      <ProviderInfo Code="962" Name="BSNL" Country="356" Currency="356">
        <PackagesList>
          <Package ServiceId="1" Name="Package 1.1" Value="110" Description="1.1 USD" />
          <Package ServiceId="1" Name="Package 2.2" Value="220" Description="2.2USD" />
          <Package ServiceId="1" Name="Package 4.4" Value="440" Description="4.4USD" />
        </PackagesList>
      </ProviderInfo>
    </PPResponse>

但是当我$xml = simplexml_load_string($response) print_r($xml)并使用Operation is completed successfully进行查看时，我只会获得file<- "soil.sil" write.table("[thickness]\nunit=m",file, append = TRUE, row.names=FALSE, quote=FALSE, col.names=FALSE) write.table(paste0("1=",L1), file, append = TRUE, row.names=FALSE, quote=FALSE, col.names=FALSE) write.table(paste0("2=",L2), file, append = TRUE, row.names=FALSE, quote=FALSE, col.names=FALSE)而没有其他内容。但我想从此xml响应中访问所有Result，OperationId和ResultMessage的值。但是当我在本地计算机中保存相同的xml响应并尝试获取数据时，我可以获取所有节点值，但它不会从URL发生。我想知道这个问题是什么？

我运行此代码并获得一个不错的XML ObjectSimpleXMLElement对象：

$string = '<PPResponse Type="Check" Key="182f55a7-ed3f-e511-940e-005056b219f6" Result="000" OperationId="61289766243683">
      <ResultMessage>Operation was successfully completed.</ResultMessage>
      <ProviderInfo Code="962" Name="BSNL" Country="356" Currency="356">
        <PackagesList>
          <Package ServiceId="1" Name="Package 1.1" Value="110" Description="1.1 USD" />
          <Package ServiceId="1" Name="Package 2.2" Value="220" Description="2.2USD" />
          <Package ServiceId="1" Name="Package 4.4" Value="440" Description="4.4USD" />
        </PackagesList>
      </ProviderInfo>
    </PPResponse>';
$text = simplexml_load_string($string);
echo "<pre>".print_r($text, true)."</pre>";

结果：

确保打印解码的xml变量，而不是响应。
