If Line Matches Anything After String, Then Do Command

I'm fairly good with grep, cut, sed, etc. However, I'm having a tough time extracting this data from a file. It looks like this:

--timestamp--  data://example1// -----| This could be anything or nothing
--timestamp--  data://example2// -----|     This could be something
--timestamp--  data://example3// -----| 
--timestamp--  data://example4// -----|      This could something else
--timestamp--  data://example5// -----| This could be another something
--timestamp--  data://example6// -----| 
--timestamp--  data://example7// -----|       This could something else

I would like to return all lines that have anything after the string -----| so the output would be:

example1
example2
example4
example5
example7

I know that I need to use an IF statement based on a grep '-----|.*$' match. It would be if there is any characters after the string, then output the line. Then, I could pipe to an awk command that would extract between the delimiters // before and after example. I'm just really stuck on how to structure the if statement.

Any help with this IF statement would be very appreciated.
