jquery 选择元素的问题

HTML code

<dd><a href="javascript:void(0)">London</a></dd>                    <dd><a href="javascript:void(0)">Bath</a></dd><dd><a href="javascript:void(0)">Bristol</a></dd><dd><a href="javascript:void(0)">Cornwall</a></dd><dd><a href="javascript:void(0)">Exeter</a></dd><dd><a href="javascript:void(0)">Plymouth</a></dd>

JScript code

var tcity="London";

如何选择链接文字=London的链接？

[解决办法]
<dd><a href="javascript:void(0)">London</a></dd>
<dd><a href="javascript:void(0)">Bath</a></dd>
<dd><a href="javascript:void(0)">Bristol</a></dd>
<dd><a href="javascript:void(0)">Cornwall</a></dd>
<dd><a href="javascript:void(0)">Exeter</a></dd>
<dd><a href="javascript:void(0)">Plymouth</a></dd>

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
var tcity="London";

alert( $('a').filter(':contains('+tcity+')').html() )


</script>
