Question

html="""<div class="practice-location">
<strong>Primary Location of Practice</strong><br/>
                        Suite 100<br/>2010 Eglinton Avenue West<br/>TorontoÂ ONÂ Â M6E 2K3<br/><strong>
</div>"""

我提取地址时遇到问题。

我希望字符串看起来像

mystr=Suite 100,2010 Eglinton Avenue West, TorontoÂ ONÂ Â M6E 2K3

我的代码：

   dt = soup.find(class_ ={"practice-location"})
   print dt
   ele=dt.find_all('strong')
   print ele
   add=[]
   for x in ele.find_next_siblings(text=True):
     add.append(x.text)
   location=','.join(add)
   print location

Answer 1

使用.extract()删除标签，并使用.replace_with替换标签

from bs4 import BeautifulSoup

html="""<div class="practice-location">
<strong>Primary Location of Practice</strong><br/>
                        Suite 100<br/>2010 Eglinton Avenue West<br/>TorontoÂ ONÂ Â M6E 2K3<br/><strong>
</div>"""

soup = BeautifulSoup(html, 'html.parser')
dt = soup.find(class_ ={"practice-location"})
# remove "strong" here
dt.strong.extract()
for br in dt.select('br'):
    br.replace_with(', ')
print(dt.text.strip().strip(',').strip())

# Suite 100, 2010 Eglinton Avenue West, TorontoÂ ONÂ Â M6E 2K3

大约3倍strip()，将<br>替换为,后，它将产生字符串

, 
                    Suite 100, 2010 Eglinton Avenue West, TorontoÂ ONÂ Â M6E 2K3,

第一个.strip()删除空格和换行符，第二个删除逗号，然后第三个再次替换空格和换行符。

您可以只执行.text或.extract，但我想您希望它们用'，'分隔

这会做到的。

from bs4 import BeautifulSoup, Tag   



def split_at_br(text):
    string = ''
    for x in text:

        if isinstance(x, str) and '\n' not in x:
            string += x

        if isinstance(x, str) and '\n' in x:
            x = x.split('\n')
            x_temp = []
            for ele in x:
                ele = ele.strip()
                x_temp.append(ele)
            x = ' '.join(x_temp)
            x = x.strip()
            string += x

        if isinstance(x, Tag):
            if x.name != 'br':
                x = x.text
                string += x
            else:
                x = ','
                string += x

    string = string[:-2].strip()
    return string

给出输出：

html="""<div class="practice-location">
<strong>Primary Location of Practice</strong><br/>
                        Suite 100<br/>2010 Eglinton Avenue West<br/>TorontoÂ ONÂ Â M6E 2K3<br/><strong>
</div>"""

soup = BeautifulSoup(html, 'html.parser')

text = soup.select('div.practice-location')
text = text[0].contents

mystr = split_at_br(text)

然后

In [1]: print (mystr)
Primary Location of Practice,Suite 100,2010 Eglinton Avenue West,TorontoÂ ONÂ Â M6E 2K3

python美丽的汤解析字符串，只有关闭br标签
