用scala解析xml

我試圖從scala.xml.XML解析來自AWIS（alexa rest apis from amazon）的xml響應，沒有任何成功。用scala解析xml

XML響應：

<?xml version="1.0"?> 
<aws:TrafficHistoryResponse xmlns:aws="http://alexa.amazonaws.com/doc/2005-10-05/"><aws:Response xmlns:aws="http://awis.amazonaws.com/doc/2005-07-11"><aws:OperationRequest><aws:RequestId>aef82596-5d7b-c72a-b97c-f31de4aedcf5</aws:RequestId></aws:OperationRequest><aws:TrafficHistoryResult><aws:Alexa>

的處理代碼：

val xml = XML.loadString(response.body) 
val response = xml \ "aws:Response" 
val data = xml \\ "aws:Data"

既響應和數據返回空nodesequences。我想這可能與命名空間有關。

任何指針如何解決這個問題將不勝感激。 TIA

嘗試請求元素不指定名稱空間：

val response = xml \ "Response" 
val data = xml \\ "Data"
