用于获取表格标签之间的文本的 Python 代码

Question

我是 Python 新手，谁能帮我写代码，让我可以从标签中获取数据？

下面是表格标签，我还需要第一个表格内的表格中存在的数据：

<table width="100%" border="0" cellspacing="0" cellpadding="0">
                  <tr> 
                    <td width="7" rowspan="2">&nbsp;</td>
                    <td width='40%'> <div align="left">

                      </div>
                    <td width="7" rowspan="2">&nbsp;</td>
                  </tr>
                  <tr> 
                    <td colspan="2"> 
    <b><font face='Arial, Helvetica, sans-serif' size='2'>Account #: 8428995632 </font></b><BR><TABLE BORDER='1' width='100%' align='center' cellspacing='0'><TR><td align='left' colspan='2'><font

                    </td>
                  </tr>
                </table>

我使用的代码是：

print BS('table')[0].text

但这只会获取第一个表格内容。

感谢您的帮助。

不真的确定OP在这里要求什么，但这就是我从问题中得到的：

下面是表格标签，我还需要第一个表格内的表格中存在的数据：

从这句话中，我怀疑您想要外部 <table> 中的一行文本，以及 first 内部 <table> 中的文本。那里在BeautifulSoup 中有很多方法可以解决这个问题，但这种方式对我来说最有意义。

# The variable "html" contains your sample html.
font_tags = html.findAll( 'font' )

# Now we print each piece of data wrapped in a <font> tag
for font_tag in font_tags:
    # This begins the second inner table, and we don't want that.
    if font_tag.text == u" Meter readings for this bill:":
        break
    else:
        print font_tag.text

这将打印以下内容：

Account #: 8428995632 
Billing Date:   07-22-2013
Past Due Date:    08-12-2013
Service From: 06-11-2013
Service To:    07-11-2013
Days of Service: 30
Current Charges:    $30,488.60
Amount Due:   $30,488.60
