Question

I am looking for two regExp statements that will

1. Determine if a text area is full of ONLY spaces with no other data (ie " " or " " n times)
2. Determine if pairs of hex values (ie A2, 81, 3B, etc.) are separated by anything other than 1 space. Two spaces, three spaces, etc. between the values is invalid.

Thank you

Answer 1

These two should work:

1. ^\s*$
2. ^([a-fA-F\d]{2}\s)*[a-fA-F\d]{2}$

For future reference, please include more information about what you’ve tried in your question. Also some testcases (especially for the second expression) would be useful.
