Loading content from a div from another website into an iframe on current page

Question

I was able to get a full page loaded into an iframe but I want a certain part of the page. I know the div id of what I need. This is my current code

onload=function(){
       var el=document.getElementById("frameContainer")
       el.innerHTML = "<iframe src=\"url\"></iframe>"
}

I was thinking of getting the full page and then grabbing the div from there and displaying it but I couldn't figure out how.

Any suggestions?

Thanks in advanced

cross-domain issues are likely to foil you. consider some sort of server-side/curl-ish solution instead?
