I always thought my CDRs smelled like roses. It weirded me out.

if you smell a spindle of fresh "Verbatim" CD-Rs for long enough, so that you get a little high, it smells like marzipan.

Ah. See, that's helpful now. Now you're helping.

None of those threads answers the question. I know how to strip out tags I don't want. I wanted to do it the other way, strip out everything BUT the ones that I DO want.

I rate all of your helpfulnesses in this thread a minus a million out of 10 so far.

Of course.

Okay. Now, with that all established, can you answer my original question?

I'm not using Perl. I'm using PHP. Which provides Perl regex functions.

Also, then, for some other language, you want to look for the PCRE library. PCRE being "Perl-Compatible Regular Expressions."

Then you can, after some initialization, plug your Perl regexps into quite a number of languages.

It's regex. It's a common syntax. If you're not part of the solution, you're part of the problem.

Which fucking regex? Shell regular expressions are not Perl regular expressions. Java's got classes for both of 'em I think. GNU Extended Regular Expressions?

Throw us a bone here, or I'll either stop or start throwing a bone to your mom.

You never specified what you were using. Here, let me help -- let me tell you about FIND and REPLACE in a text editor.

perldoc HTML::Parser

Code: Select all

use HTML&#58;&#58;Parser;
$p = HTML&#58;&#58;Parser->new&#40; ... &#41;;
$p->ignore_tags&#40; @tags &#41;;
$p->ignore_elements&#40; @tags &#41;;

Or, I'll ask even more directly:

I want to strip out all HTML tags from a string EXCEPT for a few specific ones like and and whatnot...

How how how.

by **pinback** » Mon May 02, 2005 2:45 pm

Why can't I figure this out...

I want to do WORD negation, instead of just character negation...

For instance, let's say I want to match any name which ISN'T "Ben", "Robb", or "Porkball"... something like...

/[^(Ben|Robb|Porkball)]/

...which doesn't work of course, but how do you do it?
