External RSS Feed

Awesome if someone has the magic key here.

I have this code that brings in feeds dependent on category. But I found out today, that the section needs to bring in an external RSS feed. Could anyone help me bring this in?

`<div class=”col3″>
<h2><a href=”<?= get_category_link(get_cat_id(‘Ideas’))?>”>Newest Ideas</a></h2>
<h3>Latest ideas in our Idea Exchange: </h3>
<? query_posts(‘category_name=Ideas&posts_per_page=3&paged=1’);
if(have_posts()){?>
<ul class=”list list3″>
<? while(have_posts()){the_post()?>
<li><a href=”<? the_permalink()?>”><? the_title()?></a></li>
<? }?>
</ul>
<? } wp_reset_query();?>
</div>
`

Thanks in advance!
