javascript same domain policy

[topcoder1]

I have 2 websites a and b, I want to parse the dom of b and make some modifications and then display it in a. But javascript same-domain policy prohibit reading of html dom's property at one domain from a different domain.
I'm pretty sure I've seen this being done at some sites but I don't recall. Can some guru enlighten me?
thanks!

use the http proxy to bypass this.

thanks

The Proxy services provided by the ext framework give you the ability to read anything from any source including stuff in different domains.

The feedviewer is a perfect example of this.

ds = new Ext.data.Store({
proxy: new Ext.data.HttpProxy({
url: 'feed-proxy.php'
}),
reader : reader
});
