If you need to get some remote content and republish it on your site, you can do that with PHP. Any modifications can be done this PHP and jQuery then.

To get "remote" file that is placed on the same domain (so, it's on your site) is not a big deal. Buf if you need to get some content like basketball schedule and display it on your page, there is an option

Step 1. Get remote content and make it appear on your domain:

<?php $URL = "http://www.somedoamin.com/someurl";
     $domain = file_get_contents($URL);
     echo $domain;
 ?>

Save PHP file as iframe.php

Step 2. Load it's content into your document div  with id="mydiv" using jQuery

$('#mydiv').load('http://www.yourdomain.com/iframe.php #content'

Here jQuery loads iframe.php file part, that is in between div="content" tags. So you can get only needed elements from remote content avoiding headers, banners, etc.

While calling iframe.php file, before any output it loads content from remote site.
