从xml响应中回显特定元素

Question

我有一个DHL跟踪的xml响应，我想在我的php页面上回显特定元素。

我使用以下代码打印出跟踪结果而不进行格式化：

print_r($response);

xml响应如下所示：

Array
(
    [TrackingResponse] => Array
        (
            [xmlns:req] => http://www.dhl.com
            [xmlns:xsi] => http://www.w3.org/2001/XMLSchema-instance

            [Response] => Array
                (
                    [ServiceHeader] => Array
                        (
                            [MessageTime] => 2013-12-12T11:51:05+00:00
                            [MessageReference] => j2xfhcBpCE2yd9gbeC5tjqxIX8xjDpZ1
                            [SiteID] => iraqnova
                        )

                )

            [AWBInfo] => Array
                (
                    [AWBNumber] => 8564385550

                                )

                            [DestinationServiceArea] => Array
                                (
                                    [ServiceAreaCode] => MLA

                                )

                            [ConsigneeName] => BANK OF VALLETTA P.L.C
                            [ShipmentDate] => 2013-02-14T15:14:00
                            [Pieces] => 1
                            [Weight] => 0.08

                            [Shipper] => Array
                                (
                                    [City] => Frankfurt/Main
                                    [PostalCode] => 60486
                                    [CountryCode] => DE
                                )

                            [Consignee] => Array
                                (
                                    [City] => Santa Venera
                                    [PostalCode] => 9030
                                    [CountryCode] => MT
                                )

                            [ShipperReference] => Array
                                (
                                    [ReferenceID] => Doc
                                )

                        )

                )

        )

)

我迷失了很多foreach循环以获取[ShipmentInfo]标签内的特定xml标签：

foreach($response as $tag){
echo $tag['ShipmentInfo'];
}

的样本跟踪编号和信息

谢谢，

Answer 1

$arr['TrackingResponse']['AWBInfo']['ShipmentInfo']将导致货件信息，然后使用foreach进行迭代。

喜欢 -

if(is_array($arr['TrackingResponse']['AWBInfo']['ShipmentInfo'])) {
foreach(is_array($arr['TrackingResponse']['AWBInfo']['ShipmentInfo']) as $shiptagkey=>$shiptagval)
{
echo $shiptagkey, " ", $shiptagval;
}
}

虽然$shiptagval本身就是一个数组，所以你也需要关心它。

Answer 2

print_r($response ['TrackingResponse']['AWBInfo']['ShipmentInfo']);

或者如果你不知道路径:(伪代码）

function findAndEcho($obj,$tag) {
  for $obj as $key => $val {
    if $key = $tag {
      print_r($val)
    }
    else if is_array($val) {
      findAndEcho($val,$tag)
    } 
  }
}
