Output parsed JSON to template in lift

Using Lift's json parser, how can I output parsed json objects into a template?

The datatypes that net.liftweb.json.JsonParser provides are not standard lists.

package rem.lift_client
package snippet
import net.liftweb._

import util._
import Helpers._
import net.liftweb.json.JsonParser._

class SearchResults {

  def render() = {
    v开发者_如何学Goal json_raw = "[ {\"userName\":\"John\"}, {\"userName\":\"Michael\"} ]"
    val json_parsed = parse(input)
    "li *" #> json_parsed.toString <---- NOT CORRECT
   }
 } 

In the above example, I wanted to output a list of users as:

How do I interpret the parsed object? Any ideas are welcome, thanks.

NOTE: In addition to the accepted answer, lift-json has an excellent documentation on this subject.

One way is to extract the data with case classes.

implicit val formats = DefaultFormats
case class User(userName: String)
json_parsed.extract[List[User]]
