Can't Parse custom tags in RSS item feed using SimplePie



I modified my default rss feed items to include elemnts from custom fields. It now looks like this.



<item>

		<title>Post Title</title>

		<link>http://example.com/</link>

		<pubDate>Sun, 22 Apr 2018 16:35:09 +0000</pubDate>

		<dc:creator><![CDATA[lubandi]]></dc:creator>

		<guid isPermaLink="false">http://example.com/</guid>

		<description><![CDATA[Source: AUDIO LAD]]></description>

	<field>Custom field value here</field>

	</item>



I have failed to figure out how to read the value for "field". I am using the default SimplePie to read all the other elements from the feed.



The SimplePie provides the function get_item_tags($namespace, $tag) , but i have tried and failed to get the value. This is the demo code from simple pie



$media_group = $item->get_item_tags('', 'group');

$media_content = $media_group[0]['child']['']['content'];

$file = $media_content[0]['attribs']['']['url'];

echo $file;



Any help will be greatly appreciated. Thank you.
