Question

因此，在查看代码时，读入xml时没有异常抛出...工作正常。

public void ReadXML() throws XmlPullParserException, IOException
   {

      factory = XmlPullParserFactory.newInstance();
      factory.setNamespaceAware(false);
      xpp = factory.newPullParser();

      InputStream raw = getApplicationContext().getAssets().open("trial_info.xml");
      xpp.setInput(raw,null);
   }
}

问题在于doXML方法，我试图读取文本b / w两个标签... 例如

<trial>
<title>The Book</title>
<author></author>
....
</trial>

生成的错误是18：19：41.654：W / System.err（329）：org.xmlpull.v1.XmlPullParserException：name expected（position：START_TAG @ 59:57 in java.io.InputStreamReader@44f049c8 ）

我认为代码可能比它需要的更复杂......但是无法弄清楚错误。感谢

错误消息似乎表明XML文件中存在错误，而不是代码。
