我認爲第l國家統計局2號創建這是

<!--RSS generated by RSSviaXmlTextWriter at Thu, 02 Mar 2017 16:35:42 GMT--> 

明顯的第一行被視爲由xmlpullparser評論的問題，但問題是與第二行。 解析器是我無法解析第二行，因爲它正在搜索的開始標記，它確實遇到字符。

這裏是我的解析器

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";

      xpp.setInput(reader);

Answer 1

XML文件是確定

此分析該文件，然後你可以使用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)));
