Need to provide more information of what you're wanting to do.

I see you added an example of what result is expected, can you also specify what programming language you are using?

Solution 1

You can practice with an online tool like RegExr[^]

To match all spaces, + and - symbols try:
([ +-])+

To negate the result, try:
([^ +-])+

[Edit] To match lines, try:
([ +-]*\n)+
