> i zmieniać skryptem tylko 4 i 5 wiersz

może to będzie pomocne:

<html>
	<head>
		<script type="text/javascript">

function zmien(){
	tbl = document.getElementById("txta").value.split("\n");
	if(tbl[3] != null) tbl[3] += "(4)";
	if(tbl[4] != null) tbl[4] += "(5)";
	document.getElementById("txta").value = tbl.join("\n");
}

		</script>
	</head>
	<body>
		<textarea id="txta" rows="6"></textarea>
		<input type="button" value="zm" onclick="zmien();"/>
	</body>
</html>
