Detecting Unwanted Tags

[Shawazi]

Hey I want to make a safelist so I'm using preg_match against a pattern like this:

/\<((?!a|span|b|ol|ul|li|i|em|p|div|br)[^\>]*>)/

The main problem here is that if someone puts an embed tag, it is matching with the 'em' part. I tried using

[^\>A-Za-z]*
[^\>\d\D]*

But no luck

try putting this immediately following em in your pattern:
code[/code]

[Shawazi]

that works, but then i start to create a white-list with some of a black-list, know what I mean?

[sneakyimp]

I don't know what you mean.

[Shawazi]

Well in my list I say i want tag 1 2 3 4.
The other way which works, says i want tag 1 2 3 4, but not tag 5.
I'd prefer to only have "wants" know what I mean?

[sneakyimp]

Have you tried the pattern? I'm not sure exactly how you are using it. Try what I suggested and also try just replacing 'em' with 'embed'.

Could you use [man]strip_tags[/man]?

Or at least

/<((?!(a|span|b|ol|ul|li|i|em|p|div|br)(?![a-z]))[^>]*>)/i
