That alone is about 250 calls to the QString::replace function, which does not seem optimal. I have about 5000 similar types of calls, and my strings are very large, and I would like to learn the optimal way to tackle this issue.

I program in Qt, and just thinking off the top of my head, the most optimal way I could think of tackling this was

  1. Building a hash, with hardcoded Key["ABW"] Value[" Aruba "] pairs.
  2. Building a regular expression (ABW|AFG|AGO|...|ZMB)
  3. Matching the regular expression against the string
  4. Getting a list of matches
  5. Match that list against the hash somehow, and running the requisite replace calls.

I figure while on a better track than the 250 replace functions, I do not feel confident enough to ascertain whether it is the best track, or whether it really is even necessary, because for all I know, GCC and other compilers optimizes things like this on its own.

What is the best and most optimal strategy when it comes to tackling the issue of a massive number of replace calls against a large string in terms of achieving the best performance?

Is there an industry standard when it comes to this sort of thing?
