The RegexMatch node checks if a text string matches a specified regular expression pattern. It searches the input string for any occurrence of the regex pattern and returns whether a match was found. You can configure various regex flags like case sensitivity, multiline mode, and dotall mode to control how the pattern matching behaves.
