XML アナウンスを解析するためにあなたの助けが必要です。
以下の XML を見てみましょう。

この XML を解析するために、http: //developer.android.com/training/basics/network-ops/xml.html の XML 解析に関するチュートリアルに従いました。
この XML を解析すると、次のようなエラーが発生します。
expected: START_TAG {null}NOTICES (position:START_TAG <FAVORIS>@2:10 in java.io.InputStreamReader@40e69360)
これは require によるものですが、どうすればこの問題を解決できますか?

このような XML を解析すると (以下を参照)、動作しますが、上記の XML では動作しません!
