Splitting String using Multiple Entries from a List

Question

I have following list of splitters:

    val splitd = list(" or ", " and ", " up to ")

and the following string:

    val st = "You should eat 2 kg apples a week or 2 bananas everyday; up to a month you should eat 5g of ginger everyday"

I want following output:

    val entry = List("You should eat 2 kg apples a week", "2 bananas everyday;", "a month you should eat 5g of ginger everyday")

If there is no entry in "splitd" matching the content in "st" then full string "st" should be returned. Thanks in advance for your help.

Dear @Shadowlands and @marstran, need your help again.

@jwvh No, leaving "or" was a typo. Any help now....

Check this out:

splitd.foldLeft(List(st)) {
  case (acc, spl) => acc.flatMap(item => item.split(spl).toList)
}

Thanks a lot, it worked perfectly fine. Can you please suggest any online reference where I can get a deeper understanding of Map, folding etc. etc. SCALA cookbook, I am referring to, has very simple examples.

I would recommend 'Functional Programming in Scala' by Paul Chiusano and Rúnar Bjarnason.
