How to match all characters between curly braces, provided that a specific string is present through Regex?

edit

To match all characters between curly braces provided that a specific string is present, you can use the following regular expression:

/\{\s*(specific_string)(.*?)\s*\}/s

In this expression, replace specific_string with the actual string that you want to match. The .*? matches any character (excluding newlines) zero or more times, but as few times as possible, until it reaches the closing curly brace.

Here's a breakdown of the expression:

• \{ matches the opening curly brace
• \s* matches zero or more whitespace characters
• (specific_string) matches the specific string you want to find
• (.*?) matches any character, but as few times as possible, until it reaches the closing curly brace
• \s* matches zero or more whitespace characters
• \} matches the closing curly brace
• /s enables the "dotall" mode, which allows the . character to match newlines as well as other characters
