Regex to State Machine Diagram
Regular expressions can be transformed into a state machine diagram. It is possible to map regex syntax to states and transitions.
The mapping defines the following regex syntax elements:
- Optional expression: (expression)?
- One or more occurrences: (expression)+
- Zero or more occurrences: (expression)*
- Or: (expressionA|expressionB)
