Introduction
Logs contain a large amount of text. During text processing, regular expression functions can flexibly extract keywords, perform desensitization, or determine whether specified characters are present.
For examples of common regular expressions in log scenarios, see Online Regular Expression Tester.
Purpose

regex_match Function
Function Definition
Match the data based on a regular expression, and return whether the matching is successful. You can select full matching or partial matching.
Note:
In some scenarios, this function can be replaced by the str_exist function for higher processing efficiency.
Syntax Description
regex_match(data, regex="", full=true)
Parameter Description
Parameter Name
Parameter Description
Parameter Type
Required
Default Value
Parameter Value Range
data
Field Value
string
Yes
-
-
regex
Regular Expression
string
Yes
-
-
full
full=True, complete matching. It means that the regex matches the data completely, and then the regex_match function returns True.
full=False, partial matching. It means that the regex matches part of the data, and the regex_match function returns True. 
bool
No
True
T/F
Example
Example 1: When it is determined whether the regular expression "\\d{3}.\\d{3}.\\d.\\d" fully matches 192.168.0.1, the regex_match function returns True. When it is determined whether the regular expression "\\d{3}.\\d{3}" fully matches 192.168.0.1, the regex_match function returns False.
Original log:
{"IP":"192.168.0.1", "status": "500"}
Processing rules:
//Check whether the regular expression "\\d{3}.\\d{3}.\\d.\\d" fully matches the value 192.168.0.1 of the field IP and save the result to the new field matched.
t_if_else(regex_match(v("IP"), regex="\\d{3}.\\d{3}.\\d.\\d", full=True), fields_set("matched", True),fields_set("matched", False))
//Whether the regular expression "\\d{3}.\\d{3}" fully matches the value 192.168.0.1 of the field IP:
t_if_else(regex_match(v("IP"), regex="\\d{3}.\\d{3}", full=True), fields_set("matched2", True),fields_set("matched2", False))
{"IP":"192.168.0.1","matched":"true","matched2":"false","status":"500"}
Example 2: The regex_match function returns True when it is determined whether the regular expression "\\d{3}.\\d{3}" partially matches the value 192.168.0.1 of the field IP.
Original log:
{"IP":"192.168.0.1", "status": "500"}
Processing rules:
t_if(regex_match(v("IP"), regex="\\d{3}.\\d{3}", full=False), fields_set("matched", True))
Processing result:
{"IP":"192.168.0.1","matched":"true","status":"500"}
regex_select Function
Function Definition
Match data based on a regular expression and return the corresponding partial match result. You can specify the sequence number of the matched expression and the sequence number of the group to return (partial match + sequence number of the specified matched group). If no data is matched, an empty string is returned.
Syntax Description

fields_set("match_result2", regex_select(v("data"), regex="([a-z]+)(\\d+)",index=0, group=0))
fields_set("match_result3", regex_select(v("data"), regex="([a-z]+)(\\d+)",index=0, group=1))
Processing result:
{"match_result2":"hello123","match_result1":"world456","data":"hello123,world456","match_result3":"hello","match_result":"hello123","status":"500"}
