Python：获取数据BeautifulSoup

Question

我需要 BeautifulSoup 方面的帮助，我正在尝试获取数据：

<font face="arial" font-size="16px" color="navy">001970000521</font>

它们很多，我需要获取里面的值"font"

<div id="accounts" class="elementoOculto">
            <table align="center" border="0" cellspacing=0 width="90%">         <tr><th align="left" colspan=2>                 permisos            </th></tr><tr>
    <td colspan=2>
        <table width=100% align=center border=0 cellspacing=1>
            <tr>
                <th align=center width="20%">cuen</th>
                <th align=center>Mods</th>
            </tr>
        </table>
    </td>
</tr>
</table>
<table align="center" border="0" cellspacing=1 width="90%">
    <tr bgcolor="whitesmoke" height="08">
        <td align="left" width="20%">
            <font face="arial" font-size="16px" color="navy">001970000521</font>
        </td>
        <td>......

 <table align="center" border="0" cellspacing=1 width="90%">
        <tr bgcolor="whitesmoke" height="08">
            <td align="left" width="20%">
                <font face="arial" font-size="16px" color="navy">001970000521</font>
            </td>

希望大家能帮帮我，谢谢

Answer 1

如何使用从 div 开始的 CSS selector 和 id="accounts":

soup.select("div#accounts table > tr > font")

Answer 2

您应该使用 bs4.Tag.find_all 方法或类似方法。

soup.find_all(attrs={"face":"arial","font-size":"16px","color":"navy"})

示例：

>>>import bs4 
>>>html='''<div id="accounts" class="elementoOculto">             <table align="center" border="0" cellspacing=0 width="90%">         <tr><th align="left" colspan=2>                 permisos            </th></tr><tr>     <td colspan=2>         <table width=100% align=center border=0 cellspacing=1>             <tr>                 <th align=center width="20%">cuen</th>                 <th align=center>Mods</th>             </tr>         </table>     </td> </tr> </table> <table align="center" border="0" cellspacing=1 width="90%">     <tr bgcolor="whitesmoke" height="08">         <td align="left" width="20%">             <font face="arial" font-size="16px" color="navy">001970000521</font>         </td>         <td>......   <table align="center" border="0" cellspacing=1 width="90%">         <tr bgcolor="whitesmoke" height="08">             <td align="left" width="20%">                 <font face="arial" font-size="16px" color="navy">001970000521</font>             </td> '''
>>>print bs4.BeautifulSoup(html).find_all(attrs={"face":"arial","font-size":"16px","color":"navy"})
 [<font color="navy" face="arial" font-size="16px">001970000521</font>, <font color="navy" face="arial" font-size="16px">001970000521</font>]

Answer 3

这个怎么样？

from bs4 import BeautifulSoup
str = '''<div id="accounts" class="elementoOculto">
            <table align="center" border="0" cellspacing=0 width="90%">         <tr><th align="left" colspan=2>                 permisos            </th></tr><tr>
    <td colspan=2>
        <table width=100% align=center border=0 cellspacing=1>
            <tr>
                <th align=center width="20%">cuen</th>
                <th align=center>Mods</th>
            </tr>
        </table>
    </td>
</tr>
</table>
<table align="center" border="0" cellspacing=1 width="90%">
    <tr bgcolor="whitesmoke" height="08">
        <td align="left" width="20%">
            <font face="arial" font-size="16px" color="navy">001970000521</font>
        </td>
        <td>......

 <table align="center" border="0" cellspacing=1 width="90%">
        <tr bgcolor="whitesmoke" height="08">
            <td align="left" width="20%">
                <font face="arial" font-size="16px" color="navy">001970000521</font>
            </td>'''

bs = BeautifulSoup(str)
print bs.font.string
