从XML文件中获取数据

I try to get data from XML file. The data looks like this:

<MeasuringPoints>
 <MeasuringPoint ID="Base" LastChange="2013-05-17T09:29:59.293" WeatherCondition="8">
   <Name LngID="IT">Name 1</Name>
   <Name LngID="DE">Name 2</Name>
   <Name LngID="EN>Name 3</Name>
 </MeasuringPoint>
 <MeasuringPoint ID="Middle" LastChange="2012-08-01T11:47:33.160" WeatherCondition="14">
   <Name LngID="IT">Name 1a</Name>
   <Name LngID="DE">Name 2a</Name>
   <Name LngID="EN">Name 3a</Name>
 </MeasuringPoint>
 <MeasuringPoint ID="Top" LastChange="2013-05-17T09:29:59.293" WeatherCondition="8">
   <Name LngID="DE">Name 1b</Name>
   <Name LngID="IT">Name 2b</Name>
   <Name LngID="EN">Name 3b</Name>
 </MeasuringPoint>
</MeasuringPoints>

I also have this php code:

foreach ($xml->Area as $area) 
{    
   $MEASURING_POINTS = $area->MeasuringPoints->MeasuringPoint['ID'];
   $MEASURING_LAST_CHANGE = $area->MeasuringPoints->MeasuringPoint['LastChange'];

   echo $MEASURING_POINTS;
   echo " - ";
   echo $MEASURING_LAST_CHANGE;
}

The code is working but only for first MeasuringPoint (the Base ID).

How to get the data from other MeasuringPoint (Middle and Top ID)?

Thanks for any help!

You need to iteratore over MeasuringPoint.

Try this:

foreach ($xml->Area as $area) 
{    
   foreach($area->MeasuringPoints->MeasuringPoint as $point) {
      $MEASURING_POINT = $point['ID'];
      $MEASURING_LAST_CHANGE = $point['LastChange'];

      echo $MEASURING_POINT;
      echo " - ";
      echo $MEASURING_LAST_CHANGE;
   }
}

To only get the third MeasuringPoint try this:

foreach ($xml->Area as $area) 
{    
   $point = $area->xpath("/MeasuringPoints/MeasuringPoint[@ID='Top']")
   $MEASURING_POINT = $point['ID'];
   $MEASURING_LAST_CHANGE = $point['LastChange'];

   echo $MEASURING_POINT;
   echo " - ";
   echo $MEASURING_LAST_CHANGE;
}
