Akregator and liferrea side by side

SUMMARY
Akregator doesn't read a feed that Liferea does

STEPS TO REPRODUCE
1. Add https://www.xda-developers.com/category/computing-news/ as a new feed to both Akregator and Liferea
2. Attempt to fetch/read that feed.

OBSERVED RESULT
Liferea reads the feed and displays the last few articles.  Akregator doesn't read the feed, and a mouse-over of the feed says it could not read the feed because the XML is invalid.  See the attached screenshot of Akregator and liferea side by side, with the same URL.

EXPECTED RESULT
Akregator should read the feed.

The Firefox addon "Want my RSS" also doesn't see a feed on this page. If looking at the sources, there's no link with 'type=application/rss+xml'.


The only relevant indication is this:
<h1 class="listing-title">News <a class="listing-title-rss-link icon i-feed" href="/feed/category/computing-news/"></a></h1>

which means you can use https://www.xda-developers.com/feed/category/computing-news/ but not expect feed readers to auto-discover it.

Thanks Christophe.  Using that alternate link worked.  Does that mean that Liferea is doing something wrong or outside the standard when it finds a feed at the original URL?

Not "something wrong", but more likely "something more than what the RSS spec contains" (https://www.rssboard.org/rss-autodiscovery)
