我应该测试这个功能，所以基本上称之为与预定义的内容并检查值是否被正确地解析。
I'm supposed to test this function, so basically call it with predefined content and check if the values were properly parsed.
保留一般比较是为了需要检查值集的情况，不过还要注意将在本文后面介绍更显式的some运算符。
General comparisons are retained for cases when you want to check a set of values, but also note the more explicit some operator described elsewhere in this article.
用代码生成，您还可以将验证构建进所构造的类中，从而要么自动检查值(当设置好它们时)，要么按照需要检查有效性。
With code generation, you can also build validation into the constructed classes, either automatically checking values when they are set or checking validity on demand.
由于XMLEXISTS实际上是检查值的存在，甚至“false”值的存在也将满足XMLEXISTS，因此任何文档都可以成为结果集。
Since XMLEXISTS truly checks for the existence of a value, even the existence of the value "false" satisfies XMLEXISTS so that any document qualifies for the result set.
你可以构建所有子集，检查重量是否小于背包的重量，然后选择最大值的子集。
You could construct all subsets, check that the weight is less than the weight of the knapsack, and then choose the subset with the maximum value.
如果您返回零数组，该代码的客户端必须编写额外的代码来检查返回值是否为零(如清单13所示)。
If you return a null array, the clients of the code must write extra code to check whether the return value is null (as shown in Listing 13).
与调试其他应用程序时一样，这时可以检查变量的值。
You should be able to inspect the variables as you would while debugging any application.
偏差检测是高度交互性的任务，通常需要手动检查离群值，以查明是否存在欺诈倾向、数据错误或者潜在的机遇。
Deviation detection is a highly interactive task, and outliers must usually be checked manually to see whether they indicate fraud, errors in the data, or some interesting opportunity.
所以在继续执行前，在代码中检查返回值是否为一个空句柄是非常重要的。
It is therefore important that your code checks a return value is not an empty handle before continuing execution.
这里最后的复杂之处在于可能在html、或元素上出现对齐值，因此必须检查所有的祖先元素直到找到该值为止。
The final complication here is that the alignment value might appear on the HTML or or or elements, so you have to check all of the ancestors until you find it.
调试器还允许开发人员变更并检查元素的值(图11)。
The debugger also allows developers to change and inspect values of elements (Figure 11).
该组件将解析id并检查特定模式值以表示是否应当在编辑模式下打开该文档。
The component parses the ID and checks for a specific mode value to signify whether the document should be opened in edit mode.
然后这个方法检查长度值是否小于或者等于127。
The method then checks to see if the length value is less than or equal to 127.
不用再检查默认的复合值，您也可以捕获对未定义变量的访问。
Instead of checking for a default compound value, you can also catch the access to an undefined variable. E.g.
类似地，要让DB 2确保只返回独特的结果，您不需要重复检查重复值。
Similarly, if you have DB2 ensure that only distinct results are returned, you won't have to double-check for duplicates.
这个检查通常在installshield脚本中由编写注册表脚本检查相关值来完成的。
This checking is usually done by scripting registry checks for the relevant values in the InstallShield script.
当需要第六个日志文件时，数据库管理器将检查logsecond值并将另一个日志文件分配到日志目录。
When the sixth log file is needed, the database manager will check the logsecond value and allocate another log file to the log directory.
添加或删除默认值，以及SQL检查。
sendmail会检查“调试标记”是不是比合法的值大，但是它并没有去检查这个值是不是负数。
Sendmail checked that "debug flag" values weren't larger than the legal value, but it didn't check if the number was negative.
接下来，它计算接口uuid 的散列值，检查 uuid 的格式是否有效。
Next, it computes hash value for the interface uuid and checks if uuid has a valid format.
例如，通过挂钩rowupdating事件，您能够检查新值的更新内容。
For example, by hooking the RowUpdating event you can check what is being updated against the new values.
contains (full - string, contains - string)返回一个boolean值，检查full - string是否包含contains - string。
Contains (full-string, contains-string) returns a Boolean value; it checks to see if full-string contains contains-string.
还可以使用is _ boolean函数检查提供的值是true还是false。
You can also use the is_boolean function to check whether the supplied value is true or false.
第14行中表达式的第一部分用来检查none值。
The first part of the expression in Line 14 is used to check for a value of None.
您可以过滤记录，也可以对它们进行排序，从而获得想要查看或必须检查的离群值。
You can either filter the records, or sort them to obtain the outliers you would like to review or that you must check.
首先我们分别检查每个断言的估计值。
First, let's check the estimate of each predicate individually.
可以在每个远程主机上运行此脚本，然后通过对比系统默认值检查主机之间是否有差异。
The script could be run on each remote host, and the system defaults can be compared to see if there are discrepancies between hosts.
