也就是 说,实际上在检验字符串长度的顶层代码中你没有花太多开销。
This means you have virtually no overhead on top of the actual code that determines the string's length.
所有其他非字符实体类型都被忽略,而且不进行检验,即使对于内部子集中的声明。
All other non-character entity types are ignored, and no validation is performed, even for declarations within the internal subset.
在第一个实例中,字符串是一个直接的服务级别(例如GoldService),在这种情况下它是已通过检验的、有效证书的CN。
In the first case, that string is an explicit service level, for example GoldService, and in this case it is the CN of a verified, valid certificate.
distinct将检验节点集以查找拥有相同字符串值的节点,并且只保留每个节点的一个实例,而将其余都删除。
Set: distinct examines a node set for nodes with the same string value and removes all but one instance of each.
错误:当把检验时间格式化为一个字符类型时。
一个字节通常有8位,代表一个字符,而第9位是用来检验错误的。
A byte commonly contains 8 bits to represent a single character, and the ninth bit is used for error detection.
当操作字符串并需要检验其长度是否满足某种要求时,你想当然地会使用strlen函数。
When working with strings and you need to check that the string is either of a certain length you'd understandably would want to use the strlen function.
