I am really new in this patterns part of Mathematica. Basically what I need to do is eliminate null elements from a list but that has a specific name before the empty element. For example, my list is:

list="a11-b11-", "a12-b11-1", "c11-d22-", "d33-c22-2"

and I need to obtain

list="a12-b11-1", "d33-c22-2"

The list was created using

list = Flatten[Table[ ToString[namea[[i]] <> "-" <> nameb[[j]] <> "-" <> 
 ToString[ Select[int[i, j, 0.5], Abs[#] == 0.5 &, 1] ]], 
 i, 1, 4, j, 1, 4], 1]

and for some values it writtes because there is not a value equal to $0.5$. Until now I have been able to do it term by term as

list//."a11-b11-"-> Sequence[]

but the real list contains a lot of elements and could be almost impossible to do it that way to solve the problem. I think my main problem is that I am not sure how to specify the pattern search (something like " *-name " in gnu/linux). Is there a wise way to do this?. Thanks in advance.

If the list elements are strings, as it appears after your comment, you can use Select with a string pattern:

list = "a11-b11-", "a12-b11-1", "c11-d22-", "d33-c22-2";
Select[list, Not@*StringMatchQ[__ ~~ ""]]

"a12-b11-1", "d33-c22-2"

You could also Select before making the strings:

L = DeleteCases[
 Flatten[
 Table[
 namea[[i]], nameb[[j]], Select[int[i, j, 0.5], Abs[#] == 0.5 &, 1],
 i, 4, j, 4],
 1],
 _, _, ];

and then make these into strings:

StringRiffle[ToString /@ #, "-"] & /@ L

I can't check this because you didn't supply functioning code.

In 10.1, two functions were added to handle a pair of very common cases: StringStartsQ and StringEndsQ which return True if the string matches a pattern at the beginning or end, respectively. So, while Roman's answer gives you the full general form, most of the pattern can be eliminated by using

list = "a11-b11-", "a12-b11-1", "c11-d22-", "d33-c22-2";
Select[list, Not@*StringEndsQ[""]]

instead.
