Getting and Parsing a page source
Hello,

I have looked through this site for similar subjects but couldnt find what I was looking for, forgive if I missed.

Here is what I would like to accomplish:
I load a webpage, in another domain into an iframe and I would like to get to the source code of it, or at least to the <body> tag. I dont want to edit it or pass anything to it, I just want to get the source, parse through it and depending on what I find do other stuff unrelated to that page.

Here is what I have:
<script language="javascript">
function GetSource(){
var myhtml = document.frames('gameframe').document.body.innerHT ML;
alert(myhtml);
}
</script>

Now, this works, but I get "Access Denied" error message.
I think because my parent page and the page I am looking at in the iframe are on different domains it is restricting access. I would like to know if it is possible to get around, maybe using XMLHTTPRequest or something else...

Thank you in advance

The only way to get around that is by using a server-side language to make a copy of the page on your domain.

I don't know ASP. You would need to ask in the ASP forum.

XMLHttpRequest() is bound by the domain restrictions in some browsers as well.

yea i agree with u friend

firefox is one of them.

but on the most of the browsers you can use xmlhttp .

but wait for a sec yesterday i was searching same thing to post huge data , because by using ajax it is easy to fetch data to client side but it is difficul;t to save , if u have huge data. so i tried my hand on iframe. but i am not able to navigate it so i tried on google and what i found it this
var oIfrm=document.getelementById("someIframe").contentWindow

http://codinginparadise.org/weblog/2005/08/ajax-tutorial-saving-session-across.html

go for this also it will help you
