What are good scala libraries to generate RSS feeds?

Question

Is there any scala library that can be used to generate RSS Feeds using idiomatic features like case classes? Even better if it provides helpers for using with Play framework.

Answer 1

Well, the embedded XML DSL is an idiomatic (if somewhat lambasted) feature, so I don't see why you'd need any library support. Just take a bit of RSS XML, which is valid Scala, and put in some variable content:

val myRss = 
  <rss version="2.0">

  {
    for (itemTitle <- List("foo", "bar", "baz")) yield {
      <item>
        <title>{itemTitle}</title>

      </item>
    }
  }
