validate HTML using Javascript 1

[zkent]

I have an XSLT that converts RSS to a neat and readable HTML document. The resulting HTML document uses javascript to do some fancy tricks. My HTML is table-free HTML using a CSS style sheet to display elements. My problem is that some of the RSS feeds display HTML in their content and their HTML is sometimes bad. Their bad HTML breaks my pretty HTML.

I need to know if there is a way to properly contain bad HTML so it won't affect mine or to test their HTML for errors before I try to display it.

I know Google Reader does something like this because the feeds that break my reader dont break Google. If I look at the Google source code, the offending elements are left out. How are they detecting and trapping that?

You could try loading it into an iframe...

That won't work. The RSS content is contained in the RSS feed and not from a URL. I can't use an iframe without a src URL. Interesting thought though.

Yes you can... you can dynamically write content into it using JS (even if you have to load a dummy blank file into it first, although I'm sure you don't).

If you're developing on a system that uses a security certificate (https) then you will need to use a blank html file. Otherwise attempting to utilize this frame will result in warnings on your page regarding your iframe containing non-secure content.

I had to deal with this about 2 years ago when implementing an iframe shim for a modal div on our production server that uses a security certificate. Initially importing a blank html file into the frame got rid of the security warning.

Fantastic... It's good to know these things. That reminds me - I should probably read that new AJAX security book soon!

Ok this idea is working. Now i just have to deal with the iframe height issue. Each iframe should have a different height depending on the HTML injected there. I can't have scrollbars either. Any suggestions?
