我该如何抓取这个标签？

Question

  <div id="hide-editing-34536258">1/2 and 2/1 are reciprocals.</div>

这是我要抓取并打印的标签1/2 and 2/1 are reciprocals.

我会通过 get_text() 打印它，但我不知道如何抓取标签。

我能做到。

find_all({"class":"hide-editing-3453658"}

但是要抓取的标签更多，并且在 'high-editing-'

之后它们的编号不同

而且我在数字中找不到任何规则。

谁能帮帮我？

Answer 1

属性是 id 而不是 class 并且您已经在 find_all 方法中提供了您正在查找的标签。您可以使用 regex 查找具有特定模式的所有元素。

In [61]: import re
In [62]: a = """  <div id="hide-editing-34536258">1/2 and 2/1 are reciprocals.</div>
    ...:    <div id="hide-editing-345258">1/4 and 2/1 are reciprocals.</div>
    ...:   <div id="hide-editing-346258">1/5 and 2/1 are reciprocals.</div>
    ...: """

In [63]: soup = BeautifulSoup(a, "html.parser")

In [64]: all_divs = dates = soup.findAll("div", {"id" : re.compile('hide-editing.*')})

In [65]: all_divs
Out[65]:
[<div id="hide-editing-34536258">1/2 and 2/1 are reciprocals.</div>,
 <div id="hide-editing-345258">1/4 and 2/1 are reciprocals.</div>,
 <div id="hide-editing-346258">1/5 and 2/1 are reciprocals.</div>]

In [66]: [i.text.strip() for i in all_divs]
Out[66]:
['1/2 and 2/1 are reciprocals.',
 '1/4 and 2/1 are reciprocals.',
 '1/5 and 2/1 are reciprocals.']

Answer 2

也许你可以试试正则表达式？

import re

text = '<div id="hide-editing-34536258">1/2 and 2/1 are reciprocals.</div>'
parsedText=re.findall('>([^<]+)', text)

print(parsedText[0])
