var tmpRE:RegExp = new RegExp(“([\+\*\$\/])”,”g”);

u might wanna add “(” and “)” in there.

var tmpRE:RegExp = new RegExp(“([\+\*\$\/])”,”g”);

Hey Andrei, nice article, can you tell me where to get the updated code with the fixes that you made over time as folks commented upon the original code?

I haven’t found the problem yet, but when i run this with any html containing a tag with associated attribute style=”etc.; etc.; color: rgb(#,#,#); etc.; etc.” it won’t remove that tag. for instance, the following is never removed (even when I used the RegExp “]*>”:

This has happened with , , and , I haven’t tried it with others yet. As far as I can tell, the color attribute is the only similarity

Thoughts? Ideas? This is killing me.

Thanks for your fix. Jörg. You mean line 58 in the whole source file but I guess it is line 36 in the code presented in the article.

Got it: replace line 58 with this

var tmpRE:RegExp = new RegExp("([\+\*\$\/\?])","g");

Hi! I found a strange behaviour in the code: If you try to strip the 'a' tags in the following String

google.com/?i

you will get

google.com/?ig

It's because of the "?" character I think, but so far I have no solution for it. I will post back if I find one. Cheers

Glad I could help evolve it. The changes you made are great because it lets you specify p as an allowable tag while using attributes like style=”color:#0000FF;”, but in the specific application I’m using it in I need stricter control. I can’t reproduce the closing tags not being removed issue though.

My changes still work for me in cases where you just want certain bare tags to get through. I guess it depends on the situation. Thanks for letting me know, also the working example you posted is very useful.

Hello Yoav! Just fIxed my code and created a working application. Tested your solution and found that sometimes it doesn’t remove the closing tags (, for example). So I found another better way fixing the bug you discovered. Thank you very much for your real help.
