Nice remarks! I will have to try this when I get home.


As for the stream, you are right. Also, I wouldn't say I'm a newbie and I guess novice was incorrect to say as well; if I had to call my level something, I guess I should have said a previous amateur, never reaching the expert or monkism, but a little better than a neophyte.

I've done much of this stuff before, but have since forgot. Hence, me opening the thread looking for help, but then remembering the "lookahead" was what I was after.

The issue here is that I'm going to have to manipulate this in the future. For simplicity I made the delimiters: ([]) and (\n), which may or may not have nested text. So, I used (.*) on purpose because I might want to include something in a blank div for formatting.

I know I could just write everything in HTML-like syntax, or possibly some made up pseudo-SGML, like Wiki, but that would both take the fun away and increase my typing time. -- Something just interests me about having one label.

One of my concerns is that I wanted it to be efficient. I think streaming is the best choice - no question with lengthy strings.

I don't recall what backtracking is, so I'm going to have to evaluate what moritz was talking about with: /^\[ ([^\]]+) \]/x I vaguely remember an issue like what he said with ab, but for some reason I thought the non-greedy (?) would take that away.
