# scala has elegant xml parsing baked in

import scala.xml._

# load the xml file
val style = XML.loadFile("apa.csl")

# get the title
# note: while the parser is namespace-aware, it still returns a result
(style \\ "title").text

# access the macros
val macros = style \\ "macro"

# question: how many are there?
macros.length
# answer: 13

# print the macro names
macros.foreach(macro => println(macro \\ "@name"))
