Extended information:

The following is an introduction to the regular expressions of notepad. formula rules.

1, basic expression

Symbol	Explanation
.	matches any character except a new line (\n). In other words, "." can match \r. When the file contains both \r and \n, it will cause confusion. To match all characters, use \s\S.
(…)	This matches a tag range. This tag can be accessed through the syntax \1 to access the first tag, \2 to access the second, Same reason\3\4…\9. These tags can be used in the current regular expression, or as replacement strings in search and replace.
\1, \2, etc	represents the label area from 1 to 9 (\1 to \9) in the replacement. For example, a method that finds the string Fred([1-9])XXX and replaces it with the string Sam\1YYY will replace it with Sam2YYY when the string Fred2XXX is found in the file. Note: Only 9 areas can be used, so we are safe when using them, like \10\2 means area 1 and the text "0" and area 2.
[…]	represents a set of characters, for example [abc] represents any character a, b or c. We can also use a range such as [a-z] to represent so of lowercase letters.
[^…]	represents the complement of characters. For example, [^A-Za-z] represents any character except the alphabet.
^	Matches the beginning of a line (unless in a collection, as below).
$	Match the end of the line.
*	Match 0 or more times, for example, Sa*m matches Sm, Sam, Saam, Saaam, etc.
	Match 1 or more times, for example, Sam matches Sam, Saam, Saaam, etc.
?	Match 0 or 1 times, for example, Sa?m matches Sm, Sam.
{n}	Match a certain n times. For example, 'Sa{2} m' matches Saam.
{m,n}	Matches at least m times and at most n times (any number of times if n is missing). For example, 'Sa {2,3}m' matches Saam or Saaam. 'Sa{2,}m' is the same as 'Saa m'
*?, ?, ??, {n,m }?	Non-greedy matching, matching the first valid match, usually '<.>' will match the entire 'content' string – but '<.>' will only match ". This marks a label area. These areas can be accessed multiple corresponding areas 1-9 using the syntax \1 \2, etc.

2. Marking and grouping

##(…)A group of captures. The first group can be accessed via \1, and the second via \2.(?: …)Non-capturing group.(?=…)Non-capturing group – forward assertion. For example, '(.*)( ?=ton)' expression, when encountering the 'Appleton' string, it will match 'Apple'.##(?(?!…)(?(?P…)(? =name)(?#comment)

Symbol	Explanation
Non-capturing group – backward assertion. For example, the '(?
Non-capturing group – negative forward assertion. For example, the '.(?!e)' expression, when encountering 'Apple', will find each letter Except 'l' because it immediately follows 'e'.
Non-capturing group – Negative lookbehind assertion. For example, '(?
Name the captured group. Submit a name to the group for subsequent use, for example '(?PA[^\s] )\s( ?P=first)' will find 'Apple Apple'. Similar '(A[^\s] )\s\1' uses the group name instead of the number.
Matches a group named name. (?P…).
Comment – ​​in parentheses The content will be ignored when matching.

3. Special symbols

Symbol##\s Matches spaces. Note that the end of the tag will be matched. Use [[:blank:] ] to avoid matching a new line. \SMatch non-whitespace\w Match word characters\WMatch non-word characters\dMatch numeric characters\D Matches non-numeric characters \b Matches word boundaries. '\bW\w ' Find words starting with W \B and match non-word boundaries. '\Be\B ' - Find the letter 'e'This matches the start of a word using Scintilla's definitions of words. This matches the end of a word using Scintilla's definition of words. runs with x to express characters that may have other meanings. For example, [ is used to insert into text as [ instead of as the beginning of a character set.4, character class
