Regex question.

[pinback]

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?

[pinback]

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 <i> and <b> and whatnot...

How how how.

perldoc HTML::Parser

Code: Select all

use HTML::Parser;
$p = HTML::Parser->new( ... );
$p->ignore_tags( @tags );
$p->ignore_elements( @tags );

Okay, that's awesome. Now, how about if, say, I'm not using Perl?

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

[pinback]

You never specified what you were using.

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.

Perl.

Perl.

Then why did you muddy the waters by asking for a solution if you weren't using Perl?

Perl.

Then why did you muddy the waters by asking for a solution if you weren't using Perl?

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.

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

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

[k. roo]

can you answer my original question?

You mean this one?

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

Of course.

[pinback]

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.

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

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

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