What is the easiest/best way to do this? The simplest thing that occured to me, 

open(FILE,"fileloc");
while (<FILE>) {
s/content/newcontent;
}

doesn't work. (Ignore the fact that the construct is wrong, the file just doesn't open to read and write at the same time.)

Reading the file contents into an array, modifying the array and rewriting the file is what I finally did, but replacing the entire thing instead of appending a small part (The idea is finding a match, replace it with something followed by reinserting the match) means more code and more processing time.

This may sound dumb and my solution is probably twice as dumb as this question but that's exactly the reason of this questions existence.
