android - Android 中的 XmlPullParser 问题

Question

因此，在查看代码时，读取 xml 时不会引发异常......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);
   }
}

问题出在 doXML 方法中，我试图在其中读取文本 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......但无法找出错误。谢谢

错误消息似乎表明 XML 文件中的错误，而不是代码中的错误。
