显而易见，这种方式也可以被用来检查写入数据(比如日志事务)的有效性。

Somewhat obviously, they can be used to check the validity of a block of data such as a journal transaction.

要确保能够接收到有效的数据，并且避免将错误信息写入XML，我们可以访问其参数并相应地设置ok变量。

To ensure that you receive valid data, and don't write bad information to the XML, you access the parameters and set the ok variable accordingly.

youdao

虽然通常人们不会考虑使用数据绑定来实现持久化存储，但是它可以有效地实现：读取内存中表示的XML文档并将其写入文件。

While data binding isn't usually considered a persistence method, it effectively is just that: a way to take an XML document represented in memory and write it to a file.
