Biztalk 2010中的平面文件拆分

我有包含以下数据的txt文件：

1, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
2, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
3, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
4, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
5, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
6, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India

11, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
12, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
13, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
14, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
15, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
16, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India
17, Shailender, Singh, test@test.com, 98799, 5000, New Delhi, Delhi, India

考虑到上述格式的txt文件中有20条记录

---

现在，我需要从上述文件中创建多个txt文件，每个txt文件中最多有7条记录。

使用标准平面文件向导生成您的模式，假设记录数不受限制（未绑定）

然后，手动将“Line”节点（不是根节点）的Max-occurrents属性从“Unbounded”更改为“7”。BizTalk将入站文档拆分为最多7条记录的组
