String Replace in file..is array necessary?

[Dolemite50]

Hi,

I'm attempting a recursive string replace in files. Most examples I've found read the file to an array and then step through each line performing the replace. It works like a champ, however, somewhere I saw an example where functions were being parsed from a file directly from the fileread (using RegExp). In other words, the entire file was treated as a single string. Does anybody know of any replace examples using that method? Any pros or cons?

Thanks for reading, and for any advice.

ah, that's nice, missed the FileRead...

As for handling it as a single string, you can still have a look here.

A pro is definately the speed. StringRegExp is much faster than reading from an array. It also doesn't use loops or anything like that. A con may be it is a bit difficult to read if you aren't well versed with StringRegExp (at least in my opinion). A simple comment next to the line would fix that though.

Personally, I like StringRegExp a lot more than arrays.
