我试图从（span class='Number'）中删除。代码在我要废弃的页面上如下所示：

<div id="DetailMainBox">
<table>
<tr>
<td rowspan="2" class="styleA">
<span class="UP">99&nbsp;</span><span class="Change">10.00    (-0.1%)</span>
<span class="Portfolio"><a href="../../members/index.php" class="ThemeColor" target="_blank">Menu<img src="../images/more.gif" width="11" height="11" border="0" align="absmiddle" /></a></span>
</td>



<td class="styleB">Max Quantity<span class="RT"></span><br>
<span class="Number">100.000</span></span>  </td>

<td class="styleB">Average Quantity<span class="RT"></span><br />
<span class="Number">822</span></td>

<td class="styleB">Previous Order<br />
<span class="Number">96</span></td>

<td class="styleB">Max Price<br />
<span class="Number">104</span></td>

<td class="styleB">Number of Trades<br />
<span class="Number">383</span></td>
</tr>

<tr>
<td class="styleB">Min Price<span class="RT"></span><br>
<span class="Number">59</span></td>

<td class="styleB">Total Amount<span class="RT"></span><br />
<span class="Number">800</span></td>

<td class="styleB">Start<br />
<span class="Number">10</span></td>

<td class="styleB">Low<br />
<span class="Number">98 </span></td>

我希望我能按如下方式检索该号码：最多数量：100 平均数量：822 前订单：96 最高价格：104 行业数目：383 最低价格：59 总数：800 开始：10 低位：98

请告知我的代码在处理查询时出现了什么问题。谢谢

可能的解决方案如下-深入研究bs4，您可能会得到一个更高效、更优雅的解决方案：

from bs4 import BeautifulSoup

soup = BeautifulSoup(open("bs4_test.html"), "html.parser")
tds = soup.select('td.styleB')
for td in tds:
    num = td.select('span.Number')
    for i in num:
        print ("{0} : {1}".format(td.next_element, i.string))

bs4_test.html

是您共享的html-以上几行输出：

Max Quantity : 100.000
Average Quantity : 822
Previous Order : 96
Max Price : 104
Number of Trades : 383
Min Price : 59
Total Amount : 800
Start : 10
Low : 98

bs4_test.html供参考：
