Extracting from XML using PHP

[geny]

Hi ,

There is this link -> http://data.giub.uni-bonn.de/openrouteservice/php/DetermineRoute_rajan.php?Start=7.0892567,50.7265543&Via=&End=7.0986258,50.7323634&lang=en&distunit=YD&routepref=Fastest&avoidAreas=&useTMC=false&noMotorways=false&noTollways=false&instructions=true

 

Where I want to extract 2 things (shown below in BOLD):

<xls:Instruction>Drive half left on Kaiserstraße</xls:Instruction>

<xls:distance value="284" uom="YD"/>

 

So,far I tried :

$url="url_just_shown_above";

$output = file_get_contents($url);

$xml = simplexml_load_string($output);

echo $xml->{'xls:RouteInstruction'}->{'xls:Instruction'}."<br />";

 

but it does not helps, for attribute,I used :

$xml = simplexml_load_file("url_just_shown_above");

 

foreach($xml->{'xls:distance[5]'}->attributes() as $a => $b)

{

echo $a,'="',$b,"\"</br>";

}

 

it shows nothing either.

The var_dump($xml); shows :

object(SimpleXMLElement)#1 (1) { ["@attributes"]=> array(1) { ["version"]=> string(3) "1.1" } }

 

Please help me extracting the BOLDed text from the XML file mentioned above..What wrong am I doing ? Any kind of guidance or CODE Snippet will be of great help..Will greatly appreciate the same.. Thanks a lot !

something like this?

 

<?php
  $xml = simplexml_load_file($url);
  $ns = $xml->getNamespaces();

  $routes = $xml->xpath('//xls:RouteInstruction');
  foreach($routes as $route){
    $instruction = $distance = null;
    foreach($route->children($ns['xls']) as $node){
      switch($node->getName()){
        case 'Instruction':
          $instruction = (string)$node;
          break;
        case 'distance':
          $attrs = $node->attributes();
          $distance = $attrs['value'];
          break;
      }
    }
    print "$instruction for $distance\n";
  }
?>
