Does new line match s
In regular expressions, the \n
character matches a newline character, while s
is a special character that matches a whitespace character (including spaces, tabs, and newline characters).
So, in a regular expression, \n
does not exactly match s
. However, there are a few ways to make them match:
- Using the
s
flag: If you add thes
flag to the end of your regular expression, it will make the.
character (which matches any single character, including newline characters) match newline characters as well. For example:.*s
will match any characters, including newline characters, followed by a whitespace character. - Using a character class: You can use a character class to match newline characters and whitespace characters together. For example:
[\s\n]
will match any whitespace character or newline character. - Using a negated character class: If you want to match any character that is not a newline character, you can use a negated character class:
[^\\n]
.
Here are some examples to illustrate the differences:
\n
matches a newline character only.s
matches any whitespace character (including spaces, tabs, and newline characters).[\s\n]
matches any whitespace character or newline character.[^\\n]
matches any character that is not a newline character.
