Salaam!

I have an application that take html document and do some operations on it

1- remove the unwanted tags like script, mata , object,forn totally that means the tag and it's content

2- remove the unwanted tags and keep the inner html like tag span , div

3- remove the unwanted attributes from a tag like style, size ... etc

i wanna use regular expressions to solve these questions , any idea or any piece of code will help

regards

Regex cannot handle hierarchal data to well and html is the prime example.

The problem with using regex is that fact that all html is not XHtml. Meaning that all tags are not closed so what may be displayed in html with an unclosed tag, you will end up deleting that section. Or if you have embeded tags, you may end up not removing enough and leaving unwanted information, or deleting things you need. In red show here:


<span><p>xxx</p><span><p>YYYY</p></span><p>ZZZ</p></span>
