This week's book giveaways are in the Cloud and AI/ML forums. We're giving away four copies each of Cloud Native Patterns and Natural Language Processing and have the authors on-line! See this thread and this one for details.
Well, unfortunately, RSS is supposed to be an XML dialect but in real life there is RSS-creation software that isn't as good as it should be. Or maybe people are using text editors to write RSS. Anyway, the end result is malformed XML.
You could just reject it (that would be The XML Way™). The alternative is to stop using an XML parser and use something else. I've heard about ROME for parsing RSS in Java but haven't ever used it myself.

How would I reject it? It's not throwing an error.
Could I just reject the one element with the & or do you mean just leave out that whole feed (not a good solution).

It's not throwing an exception? Then you don't have malformed XML and therefore you don't have an unescaped ampersand.
My suspicion is that you're using a SAX parser and making the common error of assuming that the characters() method in your ContentHandler will always be passed the complete contents of a text node. That isn't the case. The parser is allowed to break text into pieces and call characters() once for each piece.
I'm having a similar problem with my XML parsing; it just stops whenever an ampersand is hit. How can I modify the characters() method to ignore that case? Any sample code would be greatly appreciated.
Of course you can't modify the parser to call the characters() method differently than what it does. You have to modify your code if you want to collect all of the character data inside an element together. See the first question in the XmlFaq.
