如何在没有ROOT节点

Question

我的XML响应如下。我想跳过GIA（*其他XML的所有根节点）节点并使用List<Referenza>获取XStream是否真的可能？

XML

<?xml version="1.0" encoding="UTF-8"?>
<GIA>
  <Referenza>
    <GiaDat>20150727</GiaDat>
    <GiaMag>01</GiaMag>
    <GiaArt>SK01-0500</GiaArt>
    <GiaDes>KATSUOBUSHI POWDER 500G</GiaDes>
    <GiaLot></GiaLot>
    <GiaStm>CF</GiaStm>
    <GiaQta>88</GiaQta>
    <GiaImp>0</GiaImp>
    <GiaCon>88</GiaCon>
  </Referenza>
  <Referenza>
    <GiaDat>20150727</GiaDat>
    <GiaMag>01</GiaMag>
    <GiaArt>SK02-0500</GiaArt>
    <GiaDes>Katsuobushi Flakes 500g</GiaDes>
    <GiaLot></GiaLot>
    <GiaStm>CF</GiaStm>
    <GiaQta>130</GiaQta>
    <GiaImp>0</GiaImp>
    <GiaCon>130</GiaCon>
  </Referenza>
  ...
  ...
</GIA>

Referenza.java

import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("Referenza")
public class Referenza {
    private String GiaCon;
    private String GiaLot;
    private String GiaArt;
    private String GiaDes;
    private String GiaImp;
    private String GiaDat;
    private String GiaQta;
    private String GiaMag;
    private String GiaStm;

    // Getter-Setter
}

Test.java

String strData = strBatch.toString(); //XML Data

XStream xstream = new XStream(new DomDriver());
xstream.alias("Referenza", Referenza.class);
xstream.autodetectAnnotations(true);

/* I want the List of Referenza */
//List<Referenza> listReferenza = (List<Referenza>) xstream.fromXML(strData, Referenza.class);

如果我执行上面的代码，那么它会引发异常......

感谢Jon Skeet以下代码为我工作。

XStream xstream = new XStream(new DomDriver());
xstream.alias("GIA", List.class);
xstream.alias("Referenza", Referenza.class);
xstream.autodetectAnnotations(true);
List<Object> list=  (List<Object>) xstream.fromXML(strData, new Referenza());
