Beautifulsoup

Question

我正在尝试根据之前的 div-span 提取下一个 div 中的数据 text.below 是 html 内容，

<div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:37px; top:161px; width:38px; height:13px;"><span style="font-family: b'Times-Bold'; font-size:13px">Name
<br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:85px; top:161px; width:58px; height:13px;"><span style="font-family: b'Helvetica'; font-size:13px">Ven
    <br></span></div>

我尝试使用

查找文本

n_field = soup.find('span', text="Name\")

然后尝试使用

从下一个兄弟姐妹那里获取文本

n_field.next_sibling()

但是，由于字段中的“\n”，我无法找到范围并提取 next_sibling 文本。

简而言之，我正在尝试按照以下格式形成字典，

{"Name": "Ven"}

如有任何帮助或想法，我们将不胜感激。

您可以使用 re 而不是 bs4。

import re

html = """
    <div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:37px; top:161px; width:38px; height:13px;">
        <span style="font-family: b'Times-Bold'; font-size:13px">Name
            <br>
        </span>
    </div>
    <div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:85px; top:161px; width:58px; height:13px;">
        <span style="font-family: b'Helvetica'; font-size:13px">Ven
            <br>
        </span>
    """

mo = re.search(r'(Name).*?<span.*?13px">(.*?)\n', html, re.DOTALL)
print(mo.groups())

# for consecutive cases use re.finditer or re.findall
html *= 5
mo = re.finditer(r'(Name).*?<span.*?13px">(.*?)\n', html, re.DOTALL)

for match in mo:
    print(match.groups())

for (key, value) in re.findall(r'(Name).*?<span.*?13px">(.*?)\n', html, re.DOTALL):
    print(key, value)

我试了一下，出于某种原因，即使在删除 \n 之后，我也无法获得 nextSibling()，所以我尝试了一种不同的策略，如下所示：

from bs4 import BeautifulSoup

"""Lets get rid of the \n""" 
html = """<div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:37px; top:161px; width:38px; height:13px;"><span style="font-family: b'Times-Bold'; font-size:13px">Name<br></span></div><div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:85px; top:161px; width:58px; height:13px;"><span style="font-family: b'Helvetica'; font-size:13px">Ven<br></span></div>""".replace("\n","")
soup = BeautifulSoup(html)
span_list = soup.findAll("span")
result = {span_list[0].text:span_list[1].text.replace(" ","")}

结果为：

{'Name': 'Ven'}
