我认为第l国家统计局2号创建这是

明显的第一行被视为由xmlpullparser评论的问题，但问题是与第二行。 解析器是我无法解析第二行，因为它正在搜索的开始标记，它确实遇到字符。

这里是我的解析器

public class SitesXmlPullParserTribuneLocal{ 

    static final String KEY_SITE = "item"; 
    static final String KEY_NAME = "title"; 
    static final String KEY_LINK = "link"; 
    static final String KEY_ABOUT = "description";

      // point the parser to our file. 
      xpp.setInput(reader);

      int eventType = xpp.getEventType();

Answer 1

XML文件是确定

此分析该文件，然后你可以使用DOM和提取元素，...

 DocumentBuilderFactory builderFactory =DocumentBuilderFactory.newInstance(); 
     builderFactory.setNamespaceAware(true); 
     DocumentBuilder builder = builderFactory.newDocumentBuilder(); 
     // PARSE 
     Document document = builder.parse(new InputSource(new InputStreamReader(fis)));
