Re: HTML String Parsing

Since I am not a regex master I would do it in 2 steps. The first simply replaces every newline with a break. The second replaces every pair of breaks with a single break. The & may need to be escaped, I can't test this right now to be sure.

$comment =~ s/\n/&ltbr&gt/g;
$comment =~ s/&ltbr&gt&ltbr&gt/&ltbr&gt/g;

It's not the most elegant solution and I'm sure somebody else will whip up something really cool. It should do the trick though.

this will break if they put spaces on the blank lines and also probably won't work right if they're on a platform that sends \n\r instead of just \n. i usually use something like: `$comment = "<p>" . (join '</p><p>', grep {!/^\s+$/} split /[\n\r]+/, $comment) . "</p>";` [download] which could be adapted to use <br> instead of <p> tags if you prefer. anders pearson	[reply] [d/l]

Awesome! Thanks! That worked beautifully. I ended up using: `$comment = (join "\n<BR>", grep {!/^\s+$/} split/[\n\r]+/, $comment);` [download]	[reply] [d/l]

Hrm... Well I got printed <BR> tags when I tried putting the first part into the script so I set it to `<BR>` instead of `&ltBR&gt` and it worked the same as my original, looked neater, and used fewer variables so I kept it (thanks!). The second part produces the same results I got with my original script, however...	[reply] [d/l] [select]
