用python爬获取这样一条数据：
<td class="ip" id="ip"><p style="display: none;"></p><span></span><p style="display: none;">4</p><span></span><p style="display: none;">2</p><span>2</span><div style="display:inline-block;">2</div><span style="display:inline-block;">2</span><div style="display:inline-block;">.9</div><p style="display: none;">4</p><span>4</span><span style="display:inline-block;">.1</span><span style="display:inline-block;"></span><div style="display:inline-block;">49</div><span style="display:inline-block;">.</span><div style="display:inline-block;">13</div><span style="display:inline-block;"></span><span style="display:inline-block;"></span><span style="display:inline-block;"></span><p style="display: none;">4</p><span>4</span>:<span class="port GEGE">8976</span></td>
格式话是这样子的：
<td class="ip" id="ip"><p style="display: none;"></p><span></span>
<p style="display: none;">4</p><span></span>
<p style="display: none;">2</p><span>2</span>
<div style="display:inline-block;">2</div>
<span style="display:inline-block;">2</span>
<div style="display:inline-block;">.9</div>
<p style="display: none;">4</p><span>4</span><span style="display:inline-block;">.1</span><span
style="display:inline-block;"></span>
<div style="display:inline-block;">49</div>
<span style="display:inline-block;">.</span>
<div style="display:inline-block;">13</div>
<span style="display:inline-block;"></span><span style="display:inline-block;"></span><span
style="display:inline-block;"></span>
<p style="display: none;">4</p><span>4</span>:<span class="port GEGE">8976</span></td>
通过正则获取的数据是样子：
222.92.149.134.8976
代码如下：
/*
* \<span\>\d{1,5}\<\/span\>
* \<span\sstyle\=\"display\:inline\-block\;\"\>(\.|\.\d{1,}|\d{1,})\<\/span\>
* \<div\sstyle\=\"display\:inline\-block\;\"\>(\.|\.\d{1,}|\d{1,})\<\/div\>
