Flash Menu with Ajax/Dom

Hi,

I have got a website that basically has got the following structure:

index.php

Code:

---

<embed src="menu.swf">

<table width="100%">
<tr>
<td width="50%"><? include('index1.php') ?></td>
<td width="50%"><? include('index2.php') ?></td>
</tr>
</table>

---

The menu.swf has got some buttons that have got:

Actionscript Code:

on(release){
getURL('xpto.php')
}

What I need to know is:

Is there any AS that could change this:

Code:

---

<td width="50%"><? include('index1.php') ?></td>
<td width="50%"><? include('index2.php') ?></td>

---

to this:

Code:

---

<td width="50%"><? include('xpto1.php') ?></td>
<td width="50%"><? include('xpto2.php') ?></td>

---

without refreshing the page? Something that only changes this includes target, without refreshing the entire website?

Thanks in advance.
