Forgive me, let me clarify myself: I am actually using PHP (with PCRE extention enabled) to process user comments on a small project I am working on. I want to limit the user to have a maximum of one newline _per_ newline ... that does not make lots of sence ... let me try to explain better. The text for the comments is stored in a database. The scripts grab that text and run it through a BBCode processor. The problem is, the extra BBCode tags cause unnnececary newlines. After that, the text is ran through the nl2br() function that converts all new lines to HTML <br /> elements. So ... using BBCode tags will cause unwanted newlines and make the comment look different. I think that after running the text through the BBCode processor, then replacing all instences of more-then-one newline with a single newline is a good thing. There are a couple of other reasons that I chose to do it this way, but I dont want to get into that right now, its irelevent. So what I am looking for it a search-replace Perl regex statement that does this. If any of that was confusing, please tell me so I can "clarify" it some more.
