simple xml problems

[paul9519]

i am currently building a small client to take xml from a post http request and convert it to json

i have run into a problem

here is the code , it receives everything properly and it can print the xml;

but i cant convert it to json or access any elements of the xml, its being really weird

<?php
$c = curl_init(); 
curl_setopt($c, CURLOPT_URL, 'https://api.octranspo1.com/v1.1/GetNextTripsForStop');
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS, 'appID=00000&apiKey=000000000&stopNo=4316&routeNo=98');
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_FOLLOWLOCATION, true );
$response =  curl_exec($c);

$xml = simplexml_load_string($response)
$json = json_encode($xml);

echo $xml->asXML(); // this prints the whole xml
echo $json; // this just prints {}
curl_close( $c );
?>

and here is what it is returning

<?xml version="1.0" encoding="utf-8"?>

It seems to be having trouble with the element names with colons, so just

$response =  curl_exec($c);
$response = preg_replace("/(<\/?)(\w+)[^>]*>)/", "$1$2$3", $response);
$xml = simplexml_load_string($response); //missed semicolon here
