Can you do this? Yes.

Should you? Maybe not. Regular expressions are very powerful. So powerful that they can bite you in nasty ways unless you *really* understand what you're asking for.

Judging from your question, I'd suggest you shy away from regex for this volume of data, and maybe write non-regex code to get the job done. For the tip of the iceberg, SuperSearch on "regex performance" and do some reading...
