You notice that XML is inside the code. All I want now is to eliminate that XML code and replace or just fetch it here http://www.w3schools.com/php/books.xml from w3schools. Can you help me sir cause I was stucked with this for a week?

Answer 1

Just use the simplexml_load_file() if you want to load it from an external source:

$data = simplexml_load_file('http://www.w3schools.com/php/books.xml');

What the output looks like

Answer 2

Check the following

$xml=simplexml_load_file('http://www.w3schools.com/php/books.xml');
var_dump($xml);

Answer 3

Try this:

$content = file_get_contents(' http://www.w3schools.com/php/books.xml '); echo $content;

Simple!
