如何防止Scala的XML PrettyPrinter类删除换行符

Question

PrettyPrinter XML格式化程序从字符数据中删除换行符。我该如何防止这种情况？

scala> import scala.xml._
import scala.xml._

scala> """line one
     | line two"""
res0: java.lang.String = 
line one
line two

scala> new PrettyPrinter(999, 3).format(Elem(null, "multiline", Null, TopScope, PCData(res0)))
res1: String = <multiline><![CDATA[line one line two]]></multiline>

您可以尝试使用ConstructingParser来转义字符串，详见此处：
