Fetch several rss feeds from other blogs in one page - wordpress

Question

I am trying to make a function which take an rss fedd URL and fetches the most recent 2 posts. I have tried to remake the snippet from here to a full function in funtions.php as following. I don't want to use a plugin for this since the plugins I have looked at have been close to impossible to style with my own html...
function fetch_feed_from_blogg($path) {
$rss = fetch_feed($path);
if (!is_wp_error( $rss ) ) :
$maxitems = $rss->get_item_quantity(2);
$rss_items = $rss->get_items(0, $maxitems);
endif;
function get_first_image_url($html)
{
if (preg_match('/<img.+?src="(.+?)"/', $html, $matches)) {
return $matches[1];
}
}
function shorten($string, $length)
{
$suffix = '…';
$short_desc = trim(str_replace(array("/r", "/n", "/t"), ' ', strip_tags($string)));
$desc = trim(substr($short_desc, 0, $length));
$lastchar = substr($desc, -1, 1);
if ($lastchar == '.' || $lastchar == '!' || $lastchar == '?') $suffix='';
$desc .= $suffix;
return $desc;
}
if ($maxitems == 0) echo '<li>No items.</li>';
else
foreach ( $rss_items as $item ) :
$html = '<ul class="rss-items" id="wow-feed"> <li class="item"> <span class="rss-image"><img src="' .get_first_image_url($item->get_content()). '"/></span>
<span class="data"><h5><a href="' . esc_url( $item->get_permalink() ) . '" title="' . esc_html( $item->get_title() ) . '"' . esc_html( $item->get_title() ) . '</a></h5></li></ul>';
return $html;
}
I am also trying to make it so that it can be used several times on a single page.

Much easier to use WordPress's built-in RSS function. See https://codex.wordpress.org/Function_Reference/fetch_feed
Use it as many times as you want in a php template, or make it generate a shortcode. Style the <ul> and <li> and add a containing <div> if needed.
Example:
<?php // Get RSS Feed(s)
include_once( ABSPATH . WPINC . '/feed.php' );
// Get a SimplePie feed object from the specified feed source.
$rss = fetch_feed( 'http://example.com/rss/feed/goes/here' );
$maxitems = 0;
if ( ! is_wp_error( $rss ) ) : // Checks that the object is created correctly
// Figure out how many total items there are, but limit it to 5.
$maxitems = $rss->get_item_quantity( 5 );
// Build an array of all the items, starting with element 0 (first element).
$rss_items = $rss->get_items( 0, $maxitems );
endif;
?>
<ul>
<?php if ( $maxitems == 0 ) : ?>
<li><?php _e( 'No items', 'my-text-domain' ); ?></li>
<?php else : ?>
<?php // Loop through each feed item and display each item as a hyperlink. ?>
<?php foreach ( $rss_items as $item ) : ?>
<li>
<a href="<?php echo esc_url( $item->get_permalink() ); ?>"
title="<?php printf( __( 'Posted %s', 'my-text-domain' ), $item->get_date('j F Y | g:i a') ); ?>">
<?php echo esc_html( $item->get_title() ); ?>
</a>
</li>
<?php endforeach; ?>
<?php endif; ?>
</ul>
