Removing ads from RSS feeds?

I want to publish a news website feeds on my website. However they have included annoying banner advertising next to each headline. Is it possible to remove them from the XML feeds开发者_开发问答?

Yes, it should be easy¹ to parse the XML, remove the offending element from the heading, and then serialize the tree-structure back to a XML (RSS) file.

But, it may violate the license of the RSS file, since you'll be actively manipulating the feed.

¹⁾ You'll be editing the //rss/channel/item/title nodes.
