It seems that you would know the start and end delimiters of the matches you are trying to get, correct? (i.e. [,] or START,END etc.) So would it make sense to search for these delimiters as data from your stream comes in and then creating a sub-string between the delimiters and do further processing on those?

I know it's pretty much the same thing as rolling your own, but it will be with a more specific purpose and even be able to process it as it comes in.

The problem with regular expressions in this instance is that they work based on matches so you can only match against the amount of input you have. If you have a stream, you would have to read in all the data to get all the matches (space / time constraint issue), try to match against the character at a time brought in (pretty useless), match in chunks (again, something can be easily missed there) or generate strings of interest which if they match your criteria can be shipped off elsewhere for further processing.
