I have a text where I want to find Coordinate, Time, Time
The text is: RANDOM TEXT, Coordinate, RANDOM TEXT, Time, RANDOM TEXT, Time, RANDOM TEXT.....

These are the expresions I want to match

Code:

(\([-+]?\d*\|[-+]?\d*\))
random text
(\d*\:\d*\:\d*)
random text
(\d*\:\d*\:\d*)
random text

If I do this:

Code:

(\([-+]?\d*\|[-+]?\d*\))
(.+?)
(\d*\:\d*\:\d*)
(.+?)
(\d*\:\d*\:\d*)

The expression works, but the random text is included in the result.

What I want is to exclude the random text from the result.
So the result is COORDINATES, TIME, TIME

Any Idea?

Thanks in advance

I´m really a noob at regular expresions. But I managed to solve the problem.

The () operator is used to group a pattern. So the solution is to use .+? in the middle without the grouping.

Code:

(\([-+]?\d*\|[-+]?\d*\)) 
.+? 
(\d*\:\d*\:\d*) 
.+? 
(\d*\:\d*\:\d*)
