If I got a random string and I want to make some checks to see if it's valid or not. For example string must start with '1', length must be 20, fifth character must be different from '0' and such things like that...
What is the fatest way to achieve such verifications? I can use regex patterns if needed.
I thought about using a tJava with plain java text but maybe there is better ways.
Thank you for your help.
The easiest way will be to use the various functions in the tmap. You can also use java functions and regex functions also apart from standard functions provided in below list.
