使用正则表达式从数字范围中排除某些数字
Exclude certain numbers from range of numbers using Regular expression
有人可以帮助我使用正则表达式,我们可以从一系列数字中排除介于两者之间的某些数字。
目前,^([1-9][0][0-9])$
是配置的正则表达式。现在,如果我想从中排除一些 numbers/one number(501
,504
),那么正则表达式 look/be.
将如何
更详细的描述in this answer,您可以将以下正则表达式与“Negative Lookahead”命令一起使用?!
:
^((?!501|504)[0-9]*)$
您可以在此处查看正在执行和解释的正则表达式:https://regex101.com/r/mL0eG4/1
/^((?!501|504)[0-9]*)$/mg- ^ assert position at start of a line
- 1st Capturing group ((?!501|504)[0-9]*)
- (?!501|504) Negative Lookahead - Assert that it is impossible to match the regex below
- 1st Alternative: 501
- 501 matches the characters 501 literally
- 2nd Alternative: 504
- 504 matches the characters 504 literally
- [0-9]* match a single character present in the list below
- Quantifier: * Between zero and unlimited times, as many times as possible, giving back as needed [greedy]
- 0-9 a single character in the range between 0 and 9
- $ assert position at end of a line
- m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)
- g modifier: global. All matches (don't return on first match)
