After spending one whole evening, I found out CakePHP has its own XML class for handling xml files. In the meantime, i tried SimplePie (for RSS only, not XML), SimpleXML, and XMLize. But still they werent of any great help compared to cakephp's core XML class.

How to parse it then?
First of all, you need to import the XML class in your controller class using App::import(). Here is the controller class parsing a particular xml file and printing out (like print_r) the returned array.

Controller class:

<?

class ParseController extends AppController {
var
$name = "Parse";
var
$uses = array('MyModel');

function
xml() {
// import XML class
App::import('Xml');

// your XML file's location
$file = "my_xml_file_location.xml";

// now parse it
$parsed_xml =& new XML($file);
$parsed_xml = Set::reverse($parsed_xml);

// see the returned array
debug($parsed_xml);
}
}

?>

class XmlTestController extends AppController
{
var $name = "XmlTest";
var $uses = 'Admin';
function index()
{

App::import('Xml');

// your XML file's location
$file = "my_xml_file_location.xml";

// now parse it
$parsed_xml =& new XML($file);
$parsed_xml = Set::reverse($parsed_xml);

}
}

I am using this code to fetch xml value but it showing me Class 'App' not found in path/app/controllers/xml_test_controller.php on line 25

how to solve it, guide me please

i think you are using cakephp1.1. you need to have the latest version 1.2 for 'App' class.

I found this on: http://www.lenniez.nl/blog/category/CakePHP

about using remote xml files, rather than local files, for parsing:


3. The XML library
Coming to the next point, the XML library. I did not know CakePHP had an XML core library and that's why I had to use 'simplexml_load_string'. With the XML library you can easily convert a string to an XML object.

$xml = new Xml($input);
$xml = Set::reverse($xml);

You can even get a remote XML file by using an URL!

$xml = new Xml('http://ws.audioscrobbler.com/1.0/user/LennieZ/recenttracks.xml');
$xml = Set::reverse($xml);
