Documentation on regular expressions

I’m new to UiPath, and am trying to learn more about regular expressions. I’m using RegEx builder and have chosen Advanced. Simple example: I enter the value ^([A-Z][\w]{7,20})*$ which ensures the value entered is between 8-20 characters and begins with a capital letter. However, I’m wondering if there a link to a page that describes ALL of the various expressions and what they mean such as ^, \w, etc.? I would love to see a comprehensive list of all expressions that can be used so I can learn more about them.

Since Regex’s are used for multiple applications and generally follow the same syntax, learning about RegEx’s in general is sufficient.

You can find a tutorial on what you can do with regular expressions here.
