Obtention de données à partir du fichier XML

Question

J'essaie d'obtenir des données du fichier XML. Les données se présente comme suit:

<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> 

J'ai aussi ce code php:

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; 
} 

Le code fonctionne mais seulement pour la première MeasuringPoint (l'ID Base). Comment obtenir les données d'autres MeasuringPoint (Middle et Top ID)?

Merci pour toute aide!

Vous devez iteratore sur MeasuringPoint.

Essayez ceci:

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; 
    } 
} 

Pour seulement obtenir le troisième MeasuringPoint essayez ceci:

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; 
}
