I understand that we need to convert the regular expression to parse tree and then convert it to NFA. I am using java script. Are there any js tools for. that they're parsing. We describe a technique for building up the complete parse tree resulting from matching a text against a regular expression. In previous tagged deterministic finite-state automaton (TDFA) matching implementa- tions, all paths through the non-deterministic finite-state automaton (NFA) ... 1) NFA generation. Compile the expression into an NFA, using transitions with the epsilon symbol e. (Book 3.7.4). This translation is compositional: simply traverse the syntax tree of the regular expression. The size of the automaton is linear in the size of the expression: O(|r|). But NFAs are, in comparison to DFAs, - more ... word has little to do with the corresponding path(s) in the NFA, because of the presence of ϵ-transitions and arbitrary choices fea- tured by the latter. Since one needs the construction commands of the NFA to build a parse tree, there must exist a mechanism that al- lows one to recover a path through the NFA from a path ...

NFA states don't depend on String size. You can draw NFA in many ways for a single String. May be you are relating this with DFA substring. Thank you for your valuable comment. Stay with us ☺
