Python 正在尝试替换标签<；em>；与<；a>； 导入请求 导入字符串 从bs4导入美化组，标记 [...] def disease_spider（最大页面）： i=0 从我的理解来看，我是

，但你想用它的文本替换

em

换句话说，

a

元素包含：

import requests
import string
from bs4 import BeautifulSoup, Tag
[...]
def disease_spider(maxpages):
    i = 0
while i <= maxpages:
    url = 'http://www.cdc.gov/DiseasesConditions/az/'+ alpha[i]+'.html'
    source_code = requests.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text)
    for l in soup.findAll('a', {'class':'noLinking'}):
        x =l.find("em")
        if x is not None:
            return x.em.replaceWith(Tag('a'))

    i += 1

---

作为旁注，可能不需要进行替换，因为

a

标记的

.text

将为您提供节点的全文，包括其子节点：

for em in soup.select('a.noLinking > em'):
    em.replace_with(em.text)

[1]中的

：从bs4导入BeautifulSoup
在[2]：data=“”
...:     
...: """
[3]中：soup=BeautifulSoup（数据）
在[4]中：打印soup.a.text
包括Hib感染（流感嗜血杆菌感染）

是否可以在列表标记中找到所有带有的标记？@ks4929是。例如，将

a.noLinking>em

替换为

li a.noLinking>em

。

<a class="noLinking" href="http://www.cdc.gov/hi-disease/index.html">
    including Hib Infection (Haemophilus influenzae Infection) 
</a>

for em in soup.select('a.noLinking > em'):
    em.replace_with(em.text)

In [1]: from bs4 import BeautifulSoup

In [2]: data = """
   ...:     <a class="noLinking" href="http://www.cdc.gov/hi-disease/index.html">
   ...:         including Hib Infection (<em>Haemophilus influenzae</em> Infection)   
   ...:     </a>
   ...: """

In [3]: soup = BeautifulSoup(data)

In [4]: print soup.a.text

        including Hib Infection (Haemophilus influenzae Infection)
