Xstream Cannot create XmlPullParser错误解决
???? 昨天从官网上下了个Xstream，运行了一个简单的测试用例
public void testConvertsPropertiesObjectToShortKeyValueElements() {Properties in = new Properties();in.setProperty("hello", "world");in.setProperty("foo", "cheese");String expectedXML = "" + "<properties>\n"+ " <property name="hello" value="world"/>\n"+ " <property name="foo" value="cheese"/>\n"+ "</properties>";XStream xstream = new XStream();String actualXML = xstream.toXML(in);assertEquals(expectedXML, actualXML);Properties expectedOut = new Properties();expectedOut.setProperty("hello", "world");expectedOut.setProperty("foo", "cheese");Properties actualOut = (Properties) xstream.fromXML(actualXML);assertEquals(in, actualOut);assertEquals(in.toString(), actualOut.toString());}?? ?一运行，就报错了，错误信息如下：

?? 在初始化Xstream的地方看来下反编译的源码
??
public XStream() { this(null, (Mapper)null, ((HierarchicalStreamDriver) (new XppDriver()))); }??? 发现Xstream默认是使用XppDriver的
??? 把Xstream的Driver改为
???
XStream xstream = new XStream(new DomDriver());
??? 测试运行通过，至于为什么要使用DomDriver,还请各位大神指教，谢谢。
