jQuery prevent paste to iframe designmode from MS Word

I've seen some questions on catching the paste event. This looks helpful. But I want to prevent paste on a designmode iframe from happening when the pasted content is not plaintext, but comes from MS Word or other WYSIWYG editor.

What is Your experience on that?

I suppose I should catch the event (bind to iframe or to its body?) and look for some specific tags in th开发者_如何学编程e clipboard. What content does Ms Word add every time?

[edit] After doing more research I see there is no easy way to work with clipboard in non Internet Explorer browser except some Flash tricks. I don't want them. How can I detect paste in Firefox and others then?

JavaScript get clipboard data on paste event (Cross browser)

And also this:

Then i think, you need to go with flash object + javascript! ;-)

this is the one i have used in my project!

UPDATE:

keep in mind, that << Just because another browser allows you to do copy/past doesn't mean it's "good", "safe" or "right." >>

Firefox it's not buggy, it's just need to grant your page permission to access the clipboard!

You are probably better off catching the paste event and then cleaning the pasted content to only contain valid HTML. It will be some fun regular expressions but I am sure you can find some one who has already written some of them online.
