如何防止Scala的XML PrettyPrinter類刪除換行符

Question

PrettyPrinter XML格式化程序從字符數據中刪除換行符。我如何防止這種情況？

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>
