使用：
<div id='aaa'>
<div><img src="/u/info_img/2008-09/17/listdot11.gif" border="0" style="margin-right:5px;vertical-align:middle;"> (1111)1111 bbb,aaa,ccc,ddd</div>
<div>(2222)2222 bbb,aaa,ccc,ddd</div>
<div>(3333)3333 bbb,aaa,ccc,ddd</div>
<div>(4444)4444 bbb,aaa,ccc,ddd</div>
<div>(5555)5555 bbb,aaa,ccc,ddd</div>
<div>(5555 5555 bbb,aaa,ccc,ddd</div>
<div>(6666) 5555 bbb,aaa,ccc,ddd</div>
</div>
中把含有特定标签(1111) (2222) (3333) (4444) 的行替换为对应的链接
