加载XML文档时，最好尽可能早地捕捉到错误以免传染其他数据。
When you load an XML document, it is best to catch errors early, before they have a chance to pollute other data.
所以如果应用程序为按钮单击事件关联了错误的方法，UI测试自动化不会捕捉到逻辑错误(虽然每次测试都会失败，而且您会很快发现问题)。
So the UI test automation will not catch the logic error if the application has the wrong method wired to a button click event (although every test would fail and you'd find the problem quickly).
还要捕捉错误。
您了解了如何把数据重定向到stdin或stdout，如何使用管道，以及如何在UNIX中使用操作符；这些都有助于您编写出更强大的脚本，更好地捕捉错误，使逻辑更简洁清晰。
Knowing how to redirect data as stdin or stdout, how to use the pipe, and how to use operators in UNIX helps you write more powerful scripts with better error trapping and cleaner logic.
造成这种复杂性的部分原因是出现了一种常见的错误：通过大量的if语句捕捉所有处理逻辑来实现event方法。
This complexity is partly caused by the common mistake of implementing the event method with a large if statement to capture all the handling logic.
在本实例中(参阅图5)，我们在Validate和GenerateTopology活动上添加了故障处理程序以捕捉这个活动中产生的所有错误。
In this example (see also Figure 5), we added a fault handler on the Validate and generate Topology activities to capture all of the faults generated in that activity.
这就是——如您所期待的——一个异常处理器，它现在将会捕捉如果mkdir不能创建请求的目录而被抛出的E739错误。
This is — as you might expect — an exception handler, which will now catch the E739 error that is thrown if mkdir is unable to create the requested directory.
对于SOAP客户端来说，将这个SOAP调用封装在一个try - catch代码块中是很好的做法，这样类似于上面的SOAP错误就会被顺利地捕捉和处理。
From the SOAP client perspective, it's a good idea to wrap the SOAP call inside a try-catch block, so that SOAP faults like the one above can be caught and handled gracefully.
这就是我使用try - except块的原因：我可以捕捉自己的SQL错误，并根据需要进行响应。
This is why I used the try-except block: I can catch my own SQL errors and respond to them if needed.

The db2setup.log file captures all db2 installation information, including errors.
如果这个bug的原因不这么明显的话(常常是这种情况)，还可以用另一种方法捕捉这个错误。
You can catch this error another way, too, in case the bug isn't so obvious next time (which is usually the norm).
如果sql语句中有错误，就纠正它并重新运行应用程序；为了捕捉并纠正所有SQL错误，可能需要多次运行应用程序。
If there is an error in an SQL statement, fix it and possibly rerun the application multiple times to catch and fix additional SQL errors.
一个替代的方法是，您也可以在代码中直接捕捉这个异常，并且用其他方式处理异常(例如，可能会与使用信息一起输出真正的错误消息)。
As an alternative, you can catch this exception directly in your code and handle it some other way (perhaps printing out the actual error message along with usage information, for instance).
