Hello Monks,
I am thoroughly stuck.
Suppose one was to have a string formatted like so:
"<a a> a <a>" and one wanted to translate every character inside
<>s to upper case (it's a much simplified version of what I'm actually doing - I figure, no point in cluttering up the quesion with
[^\(\)-]s etc. Oops, too late.)
How do you go about this? Non-greedy matching won't work, because
<>s can nest. That is,
"<<a> a> a <a>" should have every char except the third 'a' modified. Non-greedy would do the first and last. Greedy will do all.
So I've been thinking that the solution must be to iterate or recurse over the string char-by-char, but I'm loathe to sinking to C-array style string parsing. Heck, I'm not even sure how to handle strings char-by-char in Perl.
Is that the only solution? Or is there a regex trick that I don't know of that makes this simple?
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
Please read these before you post! —
