Any way to display HTML as regular text?

I have an old news app that now displays stories with embedded HTML code, making them hard to read.

Is there an easy way of taking such a story and displaying it properly, without the codes?

For example, here's part of a story:

<p>The astronomer who helped kick Pluto out of the planet club believes a much larger body may be lurking in the outskirts of the solar system.</p><p>If it exists, the solar system’s ninth planet is estimated to be a gas world about 10 times bigger than Earth, California Institute of Technology (Caltech) astronomer Mike Brown wrote in this week’s Astronomical Journal.</p><p><a href="http://news.discovery.com/space/history-of-space/top-10-space-stories-of-2015-re aders-choice-151231.htm">Top 10 Space Stories of 2015: Readers' Choice</a></p><p>Brown and colleague Konstantin Batygin, also at Caltech, used mathematical models and computer simulations to deduce the planet’s existence, but they also have some observational evidence to support their claim. Several small icy bodies in the Kuiper Belt region beyond Neptune have quirks in their orbits that may be explained by the gravitational influence of a larger, more distant planetary cousin.</p>

Obviously, that's a bit tough to process! :-)
