How to Parse XML from a URL using PHP

Question

Im learning how to parse XML elements into an html document.

This takes a url with an xml, reads the elements but it ain't working...also I want to take it a bit further but I simply haven't been able to, how can I make it so I read the xml from a url? and use an xml element as filename to create an html document using a template?

////EDIT this is what I tried! /////EDIT/////EDIT/////EDIT/////EDIT/////EDIT/////EDIT

I tried this just for the sake of me knowing what Im doing(...apparently nothing haha) so I could echo if the information was right....

<?php

 $url = "http://your_blog.blogspot.com/feeds/posts/default?alt=rss";
 $xml = simplexml_load_file($url);
 print_r($xml);

?>

Thank you for your time!

It seems like this is NOT your full code and you are prematurely ending your PHP script (got ?> anywhere?) You also forgot a ; after your URL. — h2ooooooo

@h2ooooooo tried a more coventional approach but it still ain't working..... I put the url on my browser and it works(copy/paste just in case) but still getting a blank page in return(Updated the code..once more) — user1876553

Are you sure that blogspot allowed you to download data from other sources than your local server? Do you get an error? — h2ooooooo

Generally, "cross-domain" requests would be forbidden by web browsers, per the same origin security policy.

However, there is a mechanism that allows JavaScript on a web page to make XMLHttpRequests to another domain called Cross-origin resource sharing (CORS).

Read this about CORS: http://en.wikipedia.org/wiki/Cross-origin_resource_sharing

Check this article out about RSS feeds: http://www.w3schools.com/php/php_ajax_rss_reader.asp

Seems to me the xml document is in the same domain though.

No no no, it ain't, you see, I want to read an RSS feed, which is on xml. I want to read the xml, and create an html document from it using one of the elements inside....

@user1876553 You can't do that from another server unless you run it through your backend first (so instead of Client -> RSS, it'd be Client -> Server -> RSS). Check the link the elliospizzaman posted.

@h2ooooooo no, I think you guys are misunderstanding me. I read the rss(my own) feed, you get the information, right? Im trying to read it and create a file with the name of an element but that file is using a template. which has some other stuff...

@h2ooooooo changed my code for you guys to understand a little more of what Im trying to do
