[Javascript] Read/write html tag contents with Netscape

[Paul]

Thanks, Andrew.  Unfortunately, I haven't been able to get your method to
work with Netscape 4.  This is as far as I've gotten; it works with IE 6 &
Netscape 6 but fails on Netscape 4.7:

<p id="Bob">Old contents</p>

<input type="button" value="Change text" onClick="ChangeText('Bob');">

<script language="Javascript"><!--

function ChangeText(argTagName){
var W3C = (document.getElementById) ? 1 : 0; 
var IE4 = (document.all) ? 1 : 0; 
var NS4 = (document.layers) ? 1 : 0; 
	if (W3C) {
		document.getElementById(argTagName).innerHTML = "W3C";
	} else if (IE4) { 
		document.all.item(argTagName).innerText = "IE4";
	} else if (NS4) { 
		// stab in the dark!
		document.layers[argTagName].document.open();
		document.layers[argTagName].document.write("NS4");
		document.layers[argTagName].document.close();
	} else { 
		alert("Don't recognize this browser");
	}
}
--></script>

Is there something wrong with the syntax
"document.layers[argTagName].document"?

What technique can I use with Netscape 4?

Thanks! 
Paul
