Hi,
There's several ways to get values from JSON.
1. Use LINQ style query comprehension:
for { JField("bar", JInt(x)) <- json } yield x
2. Extract values with case classes
implicit val formats = net.liftweb.json.DefaultFormats
case class Foo(foo: Bar)
case class Bar(bar: Int)
json.extract[Foo]
3. XPath style
val JField("bar", JInt(x)) = json \ "foo" \ "bar"
Cheers Joni
