At long last you can do regex from blueprints!
Regular Expressions are the 10mm socket in the toolkit of string handling. Much like your 10mm socket they have been missing.
In addition to exposing regular expressions to blueprints, this toolkit includes a pattern-builder, pattern fragments and a pattern debug output to help you save time when you are working with regular expressions. Also includes string tools such as Initial Capitals, ReplaceDiacritics and PrintStringPlus.
Note that Regular Expressions are a high-level, shorthand programming language and as such you will need a basic understanding of them.
This tool can help explain what a pattern is doing: https://regex101.com/
