You can get content of iframe by using following function, than you can add content in main page html.

function getContentFromIframe(iFrameName)
{

    var myIFrame = document.getElementById(iFrameName);
    var content = myIFrame.contentWindow.document.body.innerHTML;

    //Do whatever you need with the content    

}
