This article mainly introduces how the regular expression matches the symbols and data outside the parentheses, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let the editor take you to know it.

Regular expressions match symbols outside parentheses

[\?! /\\.,\\ s] + (? = [^\)] * (\ (| $))

Match the?! /. Outside the parentheses with spaces (multiple times in a row at the same time)

Such as

String string1 = "sdfsdf sdlfksd sdf,fsdf&sdf (slug 1Magnesia 1) sdfsd sdf!?. Sdfl asdf"; String [] str = string1.split ("[\\?! /\\.,\\ s] + (? = [^\)] * (\ (| $)"); for (String s:str) {System.out.println (s);}

Results:

Sdfsdf

Sdlfksd

Sdf

Fsdf&sdf (SJV 1, GRO 1)

Sdfsd

Sdf

Sdfl

Asdf

Let's take a look at matching data outside parentheses with regular expressions.

It is easier to use regular matching data in parentheses, but it seems more difficult to match data outside parentheses. For example:

"{controller} / cc/ {action} / {id}"

I want to get the data outside the parentheses / cc/,/.

If it matches the data in parentheses (including parentheses), this can be implemented with this rule

/ {[^}] +} /

Test code (javascript implementation):

"{controller} / cc/ {action} / {id}" .replace (/ {[^}] +} / gjinghui')

But it is very difficult to extract the contents outside the parentheses. Do not know who can achieve this requirement?

Several special strings:

"{controller} / cc/ {action} / {id}}" matches the empty string "{controller}} / cc/ {action} / {id}" to:} / cc/, / Thank you for reading this article carefully.
