通过正则表达式获取字符串

Question

大家好，我有一个html代码，我想通过js正则获取每个li的内容，请问如何写这个正则。<div nid="n_0_1_0_2_1" id="rightCon">
     <h1 nid="n_0_1_0_2_1_0">重要公告</h1>
        <ul nid="n_0_1_0_2_1_1">
  <li nid="n_0_1_0_2_1_1_0">
    <span nid="n_0_1_0_2_1_1_0_0" class="time">[2010-12-02]</span><a nid="n_0_1_0_2_1_1_0_1" href="" target="_blank" title="">关于的通知</a>(阅读<span nid="n_0_1_0_2_1_1_0_2" class="FF0000">175</span>次)
  </li>
  <li nid="n_0_1_0_2_1_1_1"><span nid="n_0_1_0_2_1_1_1_0" class="time">[2010-12-02]</span><a nid="n_0_1_0_2_1_1_1_1" href="" target="_blank" title="">关于的通知</a>(阅读<span nid="n_0_1_0_2_1_1_1_2" class="FF0000">185</span>次)

Answer 1

用Jquery ,很好实现
可能不对，随便写写
var lis = $("#rightCon ul li");$(lis).each(function(){
alert($(this).html());
});

Answer 2

     /<li [^>]+?>([\d\D]+?)<\/li>/gi

Answer 3

var str = '<div nid="n_0_1_0_2_1" id="rightCon">\n\
        <h1 nid="n_0_1_0_2_1_0">ÖØÒª¹«¸æ</h1>\n\
        <ul nid="n_0_1_0_2_1_1">\n\
      <li nid="n_0_1_0_2_1_1_0">\n\
        <span nid="n_0_1_0_2_1_1_0_0" class="time">[2010-12-02]</span><a nid="n_0_1_0_2_1_1_0_1" href="" target="_blank" title="">¹ØÓÚµÄ֪ͨ</a>(ÔĶÁ<span nid="n_0_1_0_2_1_1_0_2" class="FF0000">175</span>´Î)\n\
      </li>\n\
      <li nid="n_0_1_0_2_1_1_1"><span nid="n_0_1_0_2_1_1_1_0" class="time">[2010-12-02]</span><a nid="n_0_1_0_2_1_1_1_1" href="" target="_blank" title="">¹ØÓÚµÄ֪ͨ</a>(ÔĶÁ<span nid="n_0_1_0_2_1_1_1_2" class="FF0000">185</span>´Î)\n\

      </li>\n\
    </ul>\n\
</div>';var m = str.match(/<ul[^>]*>([\s\S]*?)<\/ul>/);
m && alert(m[1]);

Answer 4

alert(str.match(/<li[\S\s]*\/li>/gi).join(""))
