The lack of regular expression support is the only thing Textastic doesn't do better than other iOS text editors I've used.

Textforce supports regular expressions, as mentioned by Mr. Levings, but Textforce is slow, annoying, and it doesn't support text highlighting. Additionally, I can't open files from DropBox into Textforce. Boo-urns.

Anyway, I hope to see regex support soon! Thanks for a great app!
