iframeInstance.contentWindow.document - this document loaded from SRC url. and vice verse - to get from inner document to parent use: parent.document

The outer page:

<html>
<body>
<iframe id="ifr1" src="page1.htm"></iframe>
<iframe id="ifr2" src="http://www.google.com"></iframe>
</body>
</html>

page1.htm:

<html>
<body>
<script type="text/javascript">
document.write(parent.document.getElementById('ifr2').src);
</script>
</body>
</html>

I am not so expert but this for your script hints, you can modify and test for your pages.
