Editing an IFrame with Javascript

[Draksis314]

I am referencing an iframe from another server in my website. The iframe is in a table format, and I want to get rid of the top two rows of the table for my website.

Is there any way I could display the iframe without the first two rows?

If the other server is effectively the same domain it should be possible. If not, not.
On my geographical filter page I load an IFRAME 4 times and inspect for a given parameter, extract the whole of the <TR> if it agrees and stitch together 4 tables of results.
I have had a frustrating few months figuring which of the various way to get at the text but finding the IFRAME by id (getElementByID) and then getting the rows by TAG (getElementsByTag - I think).
But there were several blind allies to the best pointer. innerHTML works on some, document.body.firstChild etc - I use FireFox and FireBug to find the pointers. I am sure there is a logic and syntax to the pointers but not in my head!

If you need help try looking at my code at http://www.users.waitrose.com/~cresby/fcctest3.htm but there are 800 lines just in the main file (.js). Best of luck. (I am not at my computer right now).

use something LIKE:

var iframe=document.getElementById("iframe1);
[].slice.call(iframe.contentWindow.document.getElementsByTagName("tr")).map(function(a,b){
  if(b<3){a.style.display='none'; }
});
