According to the principle of pattern recognition, a digit string is presegmented into single digits, then each of the digits is recognized by using an associated method.
它首先应用模式识别原理将待识别数字串分割为单个数字，再用一种联合式方法识别每个数字。
The format (picture) string in format-number() has digit markers with "passive" characters before or after, which are intended to be literal characters in the result
format-number() 中的格式（picture）字符串具有前后是“被动”字符的数字标识符，通常是结果中的文字。
Our example will successful parse the first 3 dates but not the final one because the final date string USES a two digit year that we have not provided a pattern for.

The alternative is to specify the individual RGB (red/green/blue) values as two-digit hexadecimal values in a string beginning with a "#".
另一种方法是指定各个RGB（red/green/blue）值，这个值以“＃”打头，后面跟着三个两位的十六进制数的字符串。
Two applications (App1 and App2) are accessing data in a Backing Map called "account bal," which contains account balances and USES the account number (a four-digit numeric string) as its key.
两个应用程序(App1和App2)正在访问名为“AccountBal”的Backingmap中的数据，Account Bal中包括帐户余额并使用帐户编号(一个四位数的数字字符串)作为其键。
Note that this specifier never displays the '0' character if it is not a significant digit, even if '0' is the only digit in the string.
请注意，如果“0”不是有效数字，此说明符永不显示“0”字符，即使“0”是字符串中唯一的数字。
If the value being formatted has a digit in the position where the '0' appears in the format string, then that digit is copied to the result string.
如果格式化的值在格式字符串中出现“0”的位置有一个数字，则此数字被复制到结果字符串中。
You can use [: digit:] in place of [0-9], and [: alpha:] is a more portable replacement for [-a-za-z0-9_]. For example, you can strip all punctuation from a string by using the statement.
您可以使用[：digit：]代替[0 - 9]，并且[：alpha：]是比[-a - zA - z0 - 9 _]更具有可移植性的替代者。
