I want to replace for example F(G(X,Y)); with H(X,Y); In RAD Studio IDE.
The regex I use is:
Find Expression: F\(G\((.+)\)\);
Replace Expression: H($1)
The result is not as I expect:
Result: H($1)
It seems the RAD Studio does not recognize the $1 as the contents between two parentheses.
Anybody have an idea?
Thanks

Find and replace text using regular expressions When you want to search and replace specific patterns of text, use regular expressions. They can help you in pattern matching, parsing, filtering of results, and so on. Once you learn the regex syntax, you can use it for almost any language.
To use RegEx, the first argument of replace will be replaced with regex syntax, for example /regex/ . This syntax serves as a pattern where any parts of the string that match it will be replaced with the new substring. The string 3foobar4 matches the regex /\d. *\d/ , so it is replaced.
The REGEXREPLACE( ) function uses a regular expression to find matching patterns in data, and replaces any matching values with a new string. standardizes spacing in character data by replacing one or more spaces between text characters with a single space.
Regex can be used to perform various tasks in Python. It is used to do a search and replace operations, replace patterns in text, check if a string contains the specific pattern.
Use {} to group the expression rather than () and \1 in the replacement text:
Find Expression: F\(G\({.+}\)\); Replace Expression: H(\0)
