Unable to generate XML file with this big URL

Question

I want to generate XML with this following code but it\'s giving error as I include big URL. Even cdata is not working:

$xml = new SimpleXMLElement(\'

        

Answer 1

You can not add CDATA sections with SimpleXML, only standard text nodes. But even that has a bug. The text can not contain entities (the &...;). The same bug exists in DOMDocument::createElement and DOMNode::$nodeValue. You can create the document with DOM however.

$dom = new DOMDocument();
$root = $dom->appendChild($dom->createElement('xml'));

for ($i = 1; $i <= 8; ++$i) {
    $track = $root->appendChild($dom->createElement('track'));
    $track
      ->appendChild($dom->createElement('path'))
      ->appendChild($dom->createTextNode('data['));
    $track
      ->appendChild($dom->createElement('title'))
      ->appendChild($dom->createCDATASection("http://r8---sn-5hn7sn7k.googlevideo.com/videoplayback?mt=1417417897&mv=m&ms=au&ip=2001:1af8:4700:a022:1::4ae9&itag=18&initcwndbps=4948750&mm=31&sver=3&id=o-AB1_DFOem6qVMtWki7uWj0CcIevyqEaY_OtwcbRPKZXT&ipbits=0&upn=IFgTkloUxQQ&expire=1417439567&fexp=902522,907259,922247,927622,932404,935694,941004,942810,943909,947209,948124,952302,952605,952901,953912,957103,957105,957201&key=yt5&sparams=dur,id,initcwndbps,ip,ipbits,itag,mm,ms,mv,source,upn,expire&source=youtube&signature=7266EE8B52AAB9E3C6DECBADDD112BDF00E85EFB.362737C47ECAE4D9E25E900E8C24483799B2A8F8&dur=1554.831&title=8+Stunning+Linguistic+Miracles+of+The+Holy+Quran+%7C+Kinetic+Typography"));
}

$dom->formatOutput = TRUE;
print($dom->saveXML());

You can see that DOM document has a bunch of methods to create the different node types. The nodes have some methods to append the new node to them.

The methods return the nodes so you can nest them.
