How to embed a html tag from a external webpage?

I am trying to embed a html tag from a external webpage,by that i mean a object tag.

I tried using iframe

<iframe srcdoc="<h1>Welcome to Twitter.</h1>" src="https://twitter.com">

but when i tried to use srdoc to embed a object it didnt work.

i also found this

<script>
        $("#siteloader")
            .html('<object data="https://twitter.com"/>');
</script>

and

<div> 
    <object type="text/html" data="https://twitter.com" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">
    </object></div>`

but i dont know how to get it to only embed an element

<object type="application/x-shockwave-flash" name="GrindPlayer" data="teststreaming/GrindPlayer.swf" width="640" height="480" id="GrindPlayer" style="visibility: visible;"><param name="allowFullScreen" value="true"><param name="flashvars" value="src=http://ift.tt/1IwOvoH"></object>
