解析具有相同标记名称的XML页面

Question

Just started getting oritented with SimpleXML and have run into a problem

I am able to parse simple xml pages like below

<something>
 <something2> value1 </something2>
 <something3> value2 </something3>
  </something>

Fairly simple to get the values of something2 and something3 if that's the only thing i need

However I am having problem with XML files that have multiple instances of a tag e.g

     <car>
       <carID>001</carID>
         <carTyre>4</carTyre>
          <carColor>Red</carColor>
            <carName>Bruce</carName>
    </car>
   <car>
     <carID>002</carID>
        <carTyre>4</carTyre>
          <carColor>Blue</carColor>
            <carName>Tom</carName>
     </car>
     <car>
          <carID>003</carID>
            <carTyre>4</carTyre>
              <carColor>Yellow</carColor>
                 <carName>Alex</carName>
   </car>
   <car>
     <carID>004</carID>
         <carTyre>4</carTyre>
            <carColor>White</carColor>
              <carName>Tina</carName>
          </car>

If i only wanted specific information (not the whole data set) for e.g

Tina - White Tome - Blue

How could I do this?

Lets say that is all in the Cars.xml, then you can try something like this:

<?php 
 $cars =  simplexml_load_file("Cars.XML"); 
 foreach($cars->xpath('//car') as $car) { 

$row = simplexml_load_string($car->asXML()); 
$v = $row->xpath('//carID[. ="004"]'); 
if($v[0]){ 
    print $car-> carName . '-' . $car-> carColor; 
 } 

} 
?>
