美丽汤 - 根据上一个 div 子标签从下一个 div 子标签中提取文本

Question

我正在尝试根据以前的div-span文本提取div下一个跨度中的数据.下面是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>

我试图使用，

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

然后尝试使用以下命令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""，我无法找到跨度并提取next_sibling文本。

简而言之，我正在尝试以以下格式形成一个字典，

{"Name": "Ven"}

对此的任何帮助或想法不胜感激。

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 之后，我也无法获得 nextSibling((，所以我尝试了不同的策略，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：

{'名称'： 'Ven'}
