This plugin was created to retrieve and cache an RSS feed for use in a template.
What you do is pass the url to the feed you would like returned and the number of minutes you would like the feed cached for. The 
plugin will cache the RSS xml and return the feed as an object which you can loop through and output however you please.
New As Of Version 1.5: 
– Fixed a typo that caused the feed to be retrieved and cached every time. Credit: Binny V A (http://www.bin-co.com/blog/) – Thanks man!
<h3>General Usage</h3>
fetch_feed_cache() is the only function you will be using with this plugin. fetch_feed_cache() accepts 2 parameters.
<ol>
<li>(string) $url – This is the URL to the feed you would like to parse</li>
<li>(int) $cache_min – This is the amount of time in minutes you would like the feed cached for.</li>
</ol>
Here is an example of the plugin being used in a template:
<pre><code><?php $xml = fetch_feed_cache("http://jrtashjian.com/feed/", 60); ?>
<h3><?=$xml->channel->title?></h3>
<ul>
 <?php if( ! empty($xml)) : ?>
 <?php foreach($xml->channel->item as $item) : ?>
 <li><a href="<?=$item->link?>"><?=$item->title?></a></li>
 <?php endforeach; ?>
 <?php else : ?>
 Delicious doesn't seem to be working at the moment...
 <?php endif; ?>
</ul>
</code></pre>
Remeber, every feed could be different. If you need to see the structure of the object returned just use print_r(). 
Example: <code><?php print_r(fetch_feed_cache("http://jrtashjian.com/feed/", 25)); ?></code>

Fetch Feed

Fetches an RSS feed and returns RSS as array

Modifies RSS feeds so that they include pages and not just posts. Deactivating the plugin restores RSS feeds to their default state.
Including pages in your feed is particularly useful if you’re using WordPress as a CMS where pages represent a good portion of your content.
The <a href="https://infolific.com/technology/software-worth-using/include-pages-in-wordpress-rss-feeds/#pro-version" rel="nofollow ugc">pro version</a> (a lifetime license is less than $15) also allows you to:
<ol>
<li>Specify that ONLY pages are included in the feeds i.e. no posts.</li>
<li>Exclude/include posts and pages by ID.</li>
<li>Add custom post types such as WooCommerce products or Avada portfolios.</li>
</ol>

RSS Includes Pages

Some people say this plugin is useless, but they don't seem to be reading the description. If you want pages to be added to your existing feeds, this plugin will do that. No settings or configuration. Just activate and go.
Some additional features are in the pro version, but 30,000+ users find the free version useful enough to keep it active. You can't argue with the numbers! :-)



Adds Pages To Feeds Just Like It Says

Completely useless plugin. Only includes posts and pages into the RSS feed. For custom post types you have to pay $10. If you plan to make money with your plugins, please say so in the description so people don't waste their time.
