If it's really just getting certain substrings out of a string then I'd go with a regex here.

Use a capturing group (make sure it's not greedy) to get the parts of the string that interest you (in this case the value property and the tag content).

val str =
  """<option value="USD">USD - United States Dollar</option><option value="JPY">JPY - Japanese Yen</option>"""
val pattern = """<option value="(.+?)">(.+?)</option>""".r

pattern.findAllMatchIn(str).foreach(x => println(x.group(1) + " " + x.group(2)))
/* output:
 * USD USD - United States Dollar
 * JPY JPY - Japanese Yen
 */
