上記の構造を持つファイル XML からバインドしようとしましたが、次のように表示したいと考えていました。
TaskId | TaskTitle | TaskDesc | TaskLong | TaskLat | TaskTime | TaskQuestionId | TaskQuestionType | TaskQuestionTitle | TaskQuestionDesc | TaskQuestionAnwser
次のような出力結果が得られます。
1 | Task of Title | Task of Desc | Task Long | Task lat | Task Time | Task Question ID | Task Question Type | TaskQuestionTitle | Task Question Desc | Task Question Answer1, Task Question Answer2
表示されない列のみTaskQuestionAnswerがあります。TaskId から までの列を持つ使用可能なテーブルにバインドして挿入する方法がわかりませんTaskQuestionDesc。
<taskQuestionAnswers>
<taskQuestionAnswer>Microsoft</taskQuestionAnswer>
<taskQuestionAnswer>Nokia Vietnam</taskQuestionAnswer>
<taskQuestionAnswer>Samsung</taskQuestionAnswer>
<taskQuestionAnswer>China Telecom</taskQuestionAnswer>
</taskQuestionAnswers>
私の問題は、バインドしてテーブルに追加する方法がわからないことを意味します。私を助けてください。どうもありがとう。
