Get content from xml file in codeigniter - codeigniter

Question

I have this code below which loads xml file from url
Question How can I get the data from it and use a foreach loop to display the content;
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function index()
{
$url = "http://xml.someurl.nz/schedule?token=mytoken";
$xml = simplexml_load_file($url);
echo "<pre>";
print_r($xml);
echo "</pre>";
foreach ($xml['meetings'] as $race) {
echo $race['metting'];
}
$this->load->view('welcome_message');
}
}
It prints out below like

Answer 1

$xml = simplexml_load_string($url);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
for json output -> echo $json;
for php array -> print_r($array);
eg: -
foreach($array as $value) {
echo $value['metting'];
}

Answer 2

I worked it out now I had to do a foreach loop with in a foreach loop
public function index()
{
$url = "http://xml.someurl.co.nz/schedule?token=sometoken";
$xml = simplexml_load_file($url);
echo "<pre>";
foreach ($xml as $key) {
foreach ($key->meeting as $value) {
echo "$value->betslip_type";
}
}
echo "</pre>";
$this->load->view('welcome_message');
}

Answer 3

You can create helper function like....
<?php
function loadXML()
{
if(file_exists('xml_load/test.xml'))
{
$xml = simplexml_load_file('xml_load/test.xml');
}
else
{
exit('Failed to open test.xml.');
}
?>
<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load("xml_load/test.xml");
$node_list = $xmlDoc->getElementsByTagName('userrole');
echo "<select name='con' class='popup_dd'>";
echo "<option value=''> Select Role</option>";
foreach($node_list AS $node)
{
$cur1 = $node->getElementsByTagName("uservalue");
$cur = $node->getElementsByTagName("name");
$v_cur = $cur->item(0)->nodeValue;
$v_cur1 = $cur1->item(0)->nodeValue;
echo "<option value=".$v_cur1.">". $v_cur. "</option>";
}
echo "</select>";
}
?>
And use this in view file <?php loadXML(); ?>
But make sure, you need to add helper file in autoload.php.
$autoload['helper'] = array('helpername');

Answer 4

first of all your XML is not valid please validate your XML then you can use foreach.

now you can use foreach or what ever you want to use
$xml = simplexml_load_string($XML);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
print_r($array);
YOU CANNOT USE ' single quote in XML VALUE LIKE THIS
