Notepad++ regular matching

---

Notepad++ regular expression string cannot exceed 69 characters

1. Supported syntax

symbol	meaning
.	Represents any character except newline
*	means match zero or more times
+	means match one to many times
?	The character to its left is matched 0 or 1 times
()	Affects the order of expression matching (parentheses similar to C++ will affect the order of expression operations), and is used as a grouping mark for expressions (marks start from 1) such as: ([az]bc)smn\1 matches "tbcsmntbc"
{}	Specifies the number of occurrences of the preceding character or group
[]	Matches any single character in the list. Such as: [ab] matches "a" or "b"; [0-9] matches any single number
[^]	matches any single character not in the list
\	Escape characters such as: To use "\" itself, you should use\\
\d	single digit
|	Matches the string on the left and right of the expression. Such as: ab|bc matches "ab" or "bc"
\d	Matches a numeric character. Equivalent to: [0-9]
\D	\d Negates, matches a non-digit character. Equivalent to:[^0-9]
\s	Match any single whitespace character: including spaces, tabs, etc. (Note: Carriage and newline characters are not included). Equivalent to: [ \t]
\S	\s negates any single character.
\w	Match any single character including underscore. Equivalent to: [A-Za-z0-9_]
\W	\w negates any single character. Equivalent to:[^A-Za-z0-9_]
\b	Match the beginning or end of a word such as: \bin matches int, but does not match sing
^	The expression to its right is matched at the beginning of the line. For example: ^A matches lines beginning with "A"
$	The expression to its left is matched at the end of the line. For example: e$ matches lines ending with "e"
\t	Tab Note: Both extensions and regular expressions are supported
\r	Carriage return character CR Note: extended support, regular expressions do not support
\n	Line break LF Note: extended support, regular expressions do not support

Note: 以换行符结尾表示是$\r\n，而不是\r\n$

Two, regular expression tricks

^   -->  代表开头
.*  -->  相当于like '%',任意字符
$   -->  代表结尾

3. Case

3.1. Matching timestamp

#时间戳示例
2022-12-21 14:22:24.123456

#表达式
\d{
    
    4}-\d{
    
    2}-\d{
    
    2} \d{
    
    2}:\d{
    
    2}:\d{
    
    2}\.\d+

3.2. Extract the specified string

#原始字符串
<program sector_size_in_bytes="512" filename="" label="fsg" num_partition_sectors="4096">
<program sector_size_in_bytes="512" filename="" label="dsg" num_partition_sectors="4096">
<program sector_size_in_bytes="512" filename="1.txt" label="dsg" num_partition_sectors="4096">
#提取部分
filename="" label="fsg"
filename="" label="dsg"
filename="1.txt" label="dsg"
#查找目标：
.*(filename.*label\=\"[^ ]*).*
#替换为： 
\1

#不查找filename为空的字符串
也就是说不匹配""这样的字符串，但是[^]这种表达式只能匹配单独字符，如果写了字符串，也会把字符串拆开单独匹配。那么如何匹配非某字符串这种形式呢？答案是零宽负向先行断言(?!pattern) 或者零宽负向后行断言(?<!pattern)
#查找目标：
#这里注意一下，(?!"")后面要加.*，代表.*中不匹配""。
filename=(?!"").* label=[^ ]*
#替换为： 
\1

3.3. Extracting words

#原始字符串
activities-activity
#提取activity
#查找目标：
(.+)-(.+)
#替换为：
\2

3.4. Find Chinese characters

[\x{
    
    4e00}-\x{
    
    9fa5}]*[\x{
    
    4e00}-\x{
    
    9fa5}]

4. Examples

4.1. Example 1: Replace all strings including the target string and after

put the following string

123abcfg
abc
abcd

#Replace with:

123hello
hello
hello

Solution: Expression replacement
Find target: abc.*$
Replace with: hello
Screenshot before replacement:
insert picture description here
Screenshot after replacement:

4.2. Example 2:

123abcfg
abc
abcd
#替换成：
123@abcfg@
@abc@
@abcd@
#表达式
(abc.*)$ 替换为：@\1@

4.3. Example 3:

str[1]abc[991]
str[2]abc[992]
str[11]abc[993]
str[222]abc[996]
#替换成
god[991]
god[992]
god[993]
god[996]

#表达式
str[[0-9]+]abc\[([0-9]+)\] 替换为：god[\1]
str[[0-9]+]abc([[0-9]+]) 替换为：god\1
OR：
str\[([0-9]+)\]abc\[([0-9]+)\] 替换为：god[\2]
str([[0-9]+])abc([[0-9]+])	替换为：god\2

4.4. Example 4:

#删除所有空行
step1：a. 选择正则表达式  b. 查找串：^[ \t]*$    替换串：空
step2：a. 选择扩展       b. 查找串：\r\n\r\n   替换串：\r\n    注：多次点击替换，直到没有可替换的字串
