Data island compatibility with macs

Data islands do not work on Macs at all.

Being that I work for a company that has to be multi-browser compatible, this presents a major problem.
here is my xml code:

<reunion>

<military>
<what>Patrol Gunboat Reunion Association</what>
<desc>A reunion is planned for Aug. 4-8 in Concord, Calif. for those who served aboard Asheville and Tacoma class boats.</desc>
<contact> Contact Terry McManuels, 1673 Kilt St., Virginia Beach, VA 23464.</contact>
</military>

<military>
<what>USS Isle Royale</what>
<desc> A reunion is planned for Aug. 5-8 in Biloxi, Miss.</desc>
<contact> Contact George Lowell, Box 307, Hatfield, AR 71945.</contact>
</military>
<reunion>

Here is the code i have on an shtml document:
<h2>Military reunions</h2><p>
<xml id="reunion" src="reunion_military.xml"></xml>
<p>
<table cellpadding=0 cellspacing=0 border="0" datasrc="#reunion" bgcolor>
<tr><td height=10></td></tr>
</tr>
<tr>
<td bgcolor="#000000"><span class="title" datafld="WHAT"></span></td></tr>
<tr bgcolor="#c0c0c0"><td><span datafld="DESC"></span><br>
<span datafld="CONTACT"></span></td>
<tr><td height=10></td></tr>
</tr>
</table>

The page works great on PCs(Netscape and IE) but nothing shows up when I try opening the page on a Mac.

Even W3C's data island examples don't work on Macs!

Can anyone suggest a solution?

Please keep in mind that I'm an amatuer programmer, but I really want to find a solution for this.

Also, this file has to be displayed inside an shtml file (or does it?) because it utilizes server-side includes all across our site.
I don't know how to get those server-side includes to work on XML files.

Any help provided on this matter would be greatly appreciated!
