求助高手,不会用正则表达式-
在网页源代码里提取下面的内容
1.根据title提取“法兰克福”和 “奥格斯堡”
源代码是:
<title>法兰克福 VS 奥格斯堡 (德甲2013/2014) - 百家欧赔 - 500彩票网</title>
2.根据game_time和odds_hd_bf,提取“2013-12-21 03:30”和“1:1”
源代码是:
<p class="game_time">比赛时间2013-12-21 03:30</p>
<p class="odds_hd_bf"><strong>1:1</strong></p>
3.提取“40.13”和“28.14”和“31.72”这三个数值,这个需要先从众多的代码中截取“平均值”和“下载”之间的代码吧,然后逐步缩小范围对么
源代码是:
...
<td row="1">平均值</td>
        <td>
          <ul class="tb_tdul td_show_cp" style="display:none;">
            <li row="1">2.31</li><li row="1">3.29</li><li row="1">2.92</li>
          </ul>
          <ul class="tb_tdul">
            <li row="1">2.28</li><li row="1">3.32</li><li row="1">3.03</li>
          </ul>
        </td>
        <td><ul class="tb_tdul td_show_cp" style="display:none;">
            <li row="1">40.13%</li><li row="1">28.14%</li><li row="1">31.72%</li>
          </ul>
          <ul class="tb_tdul">
            <li row="1">40.95%</li><li row="1">28.16%</li><li row="1">30.89%</li>
          </ul>
          </td>
        <td><p class="td_show_cp" row="1" style="display:none;">92.48%</p><p 

class="tb_tdul"><span row="1">93.35%</span></p></td>
        <td>
         <ul class="tb_tdul td_show_cp" style="display:none;">
            <li row="1">0.95</li><li row="1">0.93</li><li row="1">0.90</li>
         </ul>
          <ul class="tb_tdul" first="0.95|0.93|0.90">
            <li row="1">0.93</li><li row="1">0.94</li><li row="1">0.93</li>
          </ul>
          </td>
        <td rowspan="4"><a class="btn_blue_l btn_blue_l_h24 btn_width_auto tb_xiazai_btn" 

id="downpl" href="javascript:void(0)">下载</a></td>
...

新年了,祝大家新快乐!
