Basic Rules
- Ascii characters
- A character equals itself unless it is a special character.
- Matches are case sensitive unless the NoCase version of the RE functions are used.
- Escape
- Special characters can be treated as standard ascii characters by prefixing them with a backslash(\).
- Certain normal characters prefixed with a backslash will turn into special characters.
- period (.) - equals any character
- A pipe (|) will act as an OR between whatever is on one side or the other
- this|that - matches this or that
- Positioning
- Use a carat (^) at the start of an expression to signify the start of a string.
- Use a dollar sign($) at the end of an expression to signify the end of a string
- Both can be used together to make a more exact match
