python - BeautilfulSoup find_all 方法返回相同的元素

Question

嗨，这是我的汤对象：

<td class="kategorie">
 <div data-navi-cat="c5ff5b1d0dc93c">
  Herren
 </div>
 <div data-navi-cat="c5ff5b1d0dc95f">
  Frauen
 </div>
 <div data-navi-cat="c5ff5b1d0dc978">
  A-Jugend (U19)
 </div>
 <div data-navi-cat="c5ff5b1d0dc98c">
  B-Jugend (U17)
 </div>
 <div data-navi-cat="c5ff5b1d0dc9a2">
  C-Jugend (U15)
 </div>
 <div data-navi-cat="c5ff5b1d0dc9b1">
  U17-Juniorinnen
 </div>
 <div data-navi-cat="c5ff5b1d0dc9b6">
  Futsal
 </div>
 <div data-navi-cat="c5ff5b1d0dc9bd">
  eSport
 </div>
</td>

如何从对象中获取所有 c 代码及其相应的文本？例如：c-code：“c5ff5b1d0dc93c”及其对应的文本：第一行的“Herren”...

我的代码如下所示（类别是汤对象）：

for category in categories.find_all('div'):
    category = categories.find('div')
    print(category)

我只收到第一行的信息....

<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>
<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>
<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>
<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>
<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>
<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>
<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>
<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>

Answer 1

怎么了？

• categories保存你的 html
• 在你的循环中category = categories.find('div')-find('div')总是返回第一次出现，所以category总是<div data-navi-cat="c5ff5b1d0dc93c">Herren</div>

您应该category = element.get_text()获取文本并code = element.get('data-navi-cat')获取代码。

例子

from bs4 import BeautifulSoup
html = '''<td class="kategorie">
 <div data-navi-cat="c5ff5b1d0dc93c">
  Herren
 </div>
 <div data-navi-cat="c5ff5b1d0dc95f">
  Frauen
 </div>
 <div data-navi-cat="c5ff5b1d0dc978">
  A-Jugend (U19)
 </div>
 <div data-navi-cat="c5ff5b1d0dc98c">
  B-Jugend (U17)
 </div>
 <div data-navi-cat="c5ff5b1d0dc9a2">
  C-Jugend (U15)
 </div>
 <div data-navi-cat="c5ff5b1d0dc9b1">
  U17-Juniorinnen
 </div>
 <div data-navi-cat="c5ff5b1d0dc9b6">
  Futsal
 </div>
 <div data-navi-cat="c5ff5b1d0dc9bd">
  eSport
 </div>
</td>'''

soup = BeautifulSoup(html, "lxml")
for element in soup.find_all('div'):
    category = element.get_text()
    code = element.get('data-navi-cat')
    print(category, code)

输出

  Herren
  c5ff5b1d0dc93c

  Frauen
  c5ff5b1d0dc95f

  A-Jugend (U19)
  c5ff5b1d0dc978

  B-Jugend (U17)
  c5ff5b1d0dc98c
