as it directly loads from the CNN website -->
<!-- Start of PHP code -->
<?php
//It is adivisable to set time limit atleast 60 seconds as some articles may loads slow
set_time_limit(60);
//MyParser class contains all the required parsing functions which needs to be included first
include 'MyParser.php';
//The following statement creates an object by calling the MyParser constructor with CNN page
$myobj = new MyParser("http://www.cnn.com/world/");
//Once the object is loaded, getArticles() function parses the intital page of CNN and extracts artciiles from the other links
$articles = $myobj->getArticles($myobj->getLinks());
