Print as XML file when using cURL - php

Question

How can I display the data returned from cURL as an XML document on the page?
Currently I get something like this:
[something] => 189129
[somethingElse] => exampleContent
[somethingElse1] => someMoreExamples
[somethingElse2] => evenMoreExamples
From this code:
$url = "http://example/";
$header[] = 'Accept: application/xml';
$header[] = 'Accept-Encoding: gzip';
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_ENCODING, 'gzip');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
$xmlResponse = new SimpleXMLElement($response);
?>
<?php
print_r('<pre>');
print_r($xmlResponse);
print_r('</pre>');
?>
Is there a way to format the response directly as XML or a way to transform it after with php?
Thanks.

Edit:
If the data you are fetching is already xml, all you need to do is
echo htmlentities($xmlResponse);
Previous answer (for posterity):
I believe you can do something like:
// start your xml with a simple doctype
$xml = new SimpleXMLElement('<?xml version="1.0" standalone="yes"?><data/>');
// loop through each array entry, adding the key/value as a child to 'data'
foreach($response AS $key=>$value)
{
$xml->addChild($key, $value);
}
// get the xml
$xmlResponse = $xml->asXML();
// output it, encoding the html characters so it displays ok
echo '<pre>';
echo htmlentities($xmlResponse);
echo '</pre>';
