not able to retrieve categories

[cyril36]

Hi,

I am using Python 3.8.3 and feedparser==6.0.2
I have the following feed :

<channel>
                <atom:link href="http://joeroganexp.joerogan.libsynpro.com/rss" rel="self" type="application/rss+xml"/>
		<title>The Joe Rogan Experience</title>
		<pubDate>Fri, 27 Nov 2020 18:00:00 +0000</pubDate>
		.....
		<itunes:author>Joe Rogan</itunes:author>
		<itunes:keywords>comedian,joe,monkey,redban,rogan,talking,ufc</itunes:keywords>
		<itunes:category text="Comedy"/>
		<itunes:category text="Society &amp; Culture"/>
		<itunes:category text="Technology"/>
		<itunes:explicit>yes</itunes:explicit>
		<itunes:owner>
			<itunes:name><![CDATA[Joe Rogan]]></itunes:name>
			<itunes:email>joe@joerogan.net</itunes:email>
		</itunes:owner>
		<description><![CDATA[Conduit to the Gaian Mind]]></description>
		<itunes:subtitle><![CDATA[Joe Rogan's Weekly Podcast]]></itunes:subtitle>
		<itunes:type>episodic</itunes:type>
       <items>
          ...............

1. I want to retrieve the "categories" independently of "keywords"
2. I want to retrieve "author" independently of "itunes:owner"

First 1)

When I do the following to get one category it works , ut i can not retrieve the other categories:

            NewsFeed = feedparser.parse("http://rss_ul")
            print(NewsFeed.feed.category)

When I do the following to get several categories i get an error:

            NewsFeed = feedparser.parse("http://rss_ul")
            print(NewsFeed.feed.categories)

ERROR :

return dict.__getitem__(self, key)
KeyError: 'categories

I can retrieve the categories through the "tags" key, such as
NewsFeed.feed.get("tags")
but "tags" contains the "keywords" and "categories".
such as :

{
        "term": "comedian",
       ...
    },
    {
        "term": "joe",
        ...
    },
   ...
    {
        "term": "Comedy",  
        ...
    },
    {
        "term": "Society & Culture",
        ...
    },
    {
        "term": "Technology",
        ...
}

I want "categories" separated from "keywords".

2. same for "author" independently of "itunes:owner"

i would like to know if there is a feature where i can parse a single tag?

Thank you
