Iterate through all iframes in the document

I have a html document with code:

<body>
<iframe id="full_content_frame" src="tmpl_content1.htm" frameborder="0" width="100%">
</iframe>
<iframe id="full_content_frame" src="tmpl_content2.htm" frameborder="0" width="100%">
</iframe>
......
</body>

and in tmpl_contentX.html I have:
<body onload="resizeIframe('full_content_frame')">
.....
</body>

and main goal is to determine height of each frame and adjust iframe.height that all frames would be one by one vertically.
I am looking for any possibility to achieve that and one technique was successfull:

function resizeIframe(id)
{
parent.document.getElementById(id).style.height = (this.document.body.scrollHeight) + "px";
}

But it will correctly adjust only the first frame. How I can apply such method for all frames in parent document?
Or is there another flexible method to adjust numerous ifames?

First, id's should be unique. You cannot have two tags with the same id.

<script type="text/javascript">
function doIt() {
var d = document.getElementsByTagName('iframe');
for(var i = 0; i < d.length; i++) {
d[i].style.height = (this.document.body.scrollHeight/d.length) + "px";
}
}
</script>
<body>
<iframe id="full_content_frame" src="tmpl_content1.htm" frameborder="0" width="100%">
</iframe>
<iframe id="full_content_frame" src="tmpl_content2.htm" frameborder="0" width="100%">
</iframe>
<input type="button" onclick="doIt();" value="doIt();" />
</body>

Thanks, but how to do it automatically?
Becides, height of all frames would be the same.

Check this:

<body>
<iframe id="full_content_frame" src="tmpl_content1.htm" frameborder="0" width="100%">
</iframe>
<iframe id="full_content_frame" src="tmpl_content2.htm" frameborder="0" width="100%">
</iframe>
<iframe id="full_content_frame" src="tmpl_content3.htm" frameborder="0" width="100%">
</iframe>
<iframe id="full_content_frame" src="tmpl_content4.htm" frameborder="0" width="100%">
</iframe>
<script>
var frm = window.frames;
var pct = parseInt(1/frm.length*100)+"%";
alert(pct)
for(var i=0;i<frm.length;i++){
frm[i].frameElement.style.height=pct;
}
</script>
</body>
