If you're OK with textual code generation, you can also use something like re2c: http://re2c.org/ http://re2c.org/ And then you get the power of regexes too.

If you're OK with textual code generation, you can also use something like re2c: http://re2c.org/ http://re2c.org/ And then you get the power of regexes too. re2c will match an arbitrary set of regexes (including constant strings) by walking through the string byte-by-byte, a single time. A trie is basically a special case of a DFA.
