我有一个DHL跟踪的xml响应，我想在我的php页面上回显特定的元素。
我使用以下代码打印出不带格式的跟踪结果：
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

[ShipperReference] => Array

)
)
)
我弄丢了太多foreach循环来获取[ShipmentInfo]标签中的特定xml标签：
foreach($response as $tag){
echo $tag['ShipmentInfo'];
}
样品跟踪编号和信息，来自DHL XML Service Validation网站http://xmlpitest-ea.dhl.com/serviceval/jsps/main/Main_menu.jsp
谢谢你，
$arr['TrackingResponse']['AWBInfo']['ShipmentInfo']将导致装运信息，然后使用foreach对此进行迭代。
类似-
if(is_array($arr['TrackingResponse']['AWBInfo']['ShipmentInfo'])) {
foreach(is_array($arr['TrackingResponse']['AWBInfo']['ShipmentInfo']) as $shiptagkey=>$shiptagval)
{
echo $shiptagkey, " ", $shiptagval;
}
}
虽然$shiptagval本身将是一个数组，所以您也需要关心这一点。
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)
}
}
}
