Array Help - PHP XML

My code (PHP):


<html>
<head>
<link href='http://ift.tt/OIiP2w' rel='stylesheet' type='text/css'>
<style>
body {
    background-color: rgba(255, 255, 255, 0.3);
    font-family: 'Open Sans', sans-serif;
    text-align:center;
}
</style>
</head>
      <?php
    $url = 'http://ift.tt/1H1P10S';

    $parser = new XMLReader;
    $parser->open($url);

    while ($parser->read()) {
        if ($parser->nodeType === XMLReader::ELEMENT) {

            while ($parser->name === 'pod' && $parser->getAttribute('title') !== 'Result')
                $parser->next('pod'); // jump to the next pod node 

            if ($parser->name === 'plaintext') {
                $str = $parser->readString();
                $parser->close();    
                break;
            }
        }
    }

    $lines = explode("\n", $str);
    $result = array();

    foreach ($lines as $line) {
        $fields = explode(' | ', $line);
        $flight = array_shift($fields);
        $flight = $flight . "<hr>"; //DELETE IF DOESN'T WORK

        if ($flight === '')
            $cols = $fields;
        elseif (isset($fields[1])) {
            $result[$flight][$cols[0]] = $fields[0];
            $result[$flight][$cols[1]] = $fields[1];
        } 
    }

    foreach($result as $key=>$value)
    {
        echo $key;
        foreach($value as $value1){

        echo $value1;
echo " &nbsp;";
}
    }

Basically uses Wolfram Alpha API to get planes nearby, then display it. Issue how can I remove the plane direction and the phrase 'Slant distance'

Sample output below:


slant distance  ENY flight 3278
14 miles NNW  Frontier Airlines flight 72
44 miles N  American Airlines flight 1241
15 miles NW  American Airlines flight 396
23 miles W  Atlantic Southeast Airlines flight 6104
49 miles SSE

So, again, I just need 'Slant Distance' & n miles direction remove.

Thank you
