get contents from another page using php?

I'm not sure this is possible or not. I want a php script when executed , it will go to a page (on a different domain) and get the html contents of it and inside the html there's links , and that script is able to get each link's href.

html code:

<div id="somediv">
  <a href="http://yahoo.com" class="url">Yahoo</a>
  <a href="http://google.com" class="url">Google</a>
  <a href="http://facebook.com" class="url">Facebook</a>
</div>

The output code(which php will echo out) will be
http://yahoo.com
http://google.com
http://facebook.com

I have heard of cURL in php can do something like this but not exactly like this , i'm a bit confused , i hope some can guide me on this.

Thanks.

Using DOM and XPath:

<?php
$doc = new DOMDocument();
$doc->loadHTMLFile("http://www.example.com/"); // or you could load from a string using loadHTML();
$xpath = new DOMXpath($doc);
$elements = $xpath->query("//div[@id='somediv']//a");
foreach($elements as $elem){
    echo $elem->getAttribute('href');
}

BTW: you should read up on DOM and XPath.
