Msg ExReg is a simple and immediate iMessage app. You can copy any text and use the regular expression to extract everything you want.
The extracted result can be inserted into your message and sent to whoever you want. Quick and easy and, if you have ExReg, you can take advantage of previously saved regexes. And if you have a doubt, go to the ICU website to find the answers you are looking for.
Sorry for English (thanks Google Translate) and if you want to help me to evolve the app write me with tips and ideas; thank you!
