我是靠谱客的博主漂亮口红，最近开发中收集的这篇文章主要介绍23-python用BeautifulSoup用抓取a标签内所有数据，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.获取子标签：

thr_msgs = soup.find_all('div',class_=re.compile('msg'))

for i in thr_msgs:

print (i)

first = i.select( 'em:nth-of-type(1)' )

print (first)

>>>

<div class = '"msg"' ><em>佛山< / em><em> 1 - 3 年< / em><em>大专< / em>< / div>

[<em>佛山< / em>]

<div class = '"msg"' ><em>南京< / em><em> 3 - 5 年< / em><em>本科< / em>< / div>

[<em>南京< / em>]

<div class = '"msg"' ><em>南阳< / em><em> 1 - 3 年< / em><em>大专< / em>< / div>

[<em>南阳< / em>]

<div class = '"msg"' ><em>深圳< / em><em> 1 年以内< / em><em>本科< / em>< / div>

[<em>深圳< / em>]

2.过去一个标签内内容：

#标签操作
from bs4 import BeautifulSoup
import urllib.request
import re
#如果是网址，可以用这个办法来读取网页
#html_doc = "http://tieba.baidu.com/p/2460150866"
#req = urllib.request.Request(html_doc)
#webpage = urllib.request.urlopen(req)
#html = webpage.read()
html="""
<html><head><title>The Dormouse's story</title></head>
<body>
<p class="title" name="dromouse"><b>The Dormouse's story</b></p>
<p class="story">Once upon a time there were three little sisters; and their names were
<a href="http://example.com/elsie" class="sister" id="xiaodeng"><!-- Elsie --></a>,
<a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and
<a href="http://example.com/tillie" class="sister" id="link3">Tillie</a>;
<a href="http://example.com/lacie" class="sister" id="xiaodeng">Lacie</a>
and they lived at the bottom of a well.</p>
<p class="story">...</p>
"""
soup = BeautifulSoup(html, 'html.parser') #文档对象
#查找a标签,只会查找出一个a标签
#print(soup.a)#<a class="sister" href="http://example.com/elsie" id="xiaodeng"><!-- Elsie --></a>
for k in soup.find_all('a'):
print(k)
print(k['class'])#查a标签的class属性
print(k['id'])#查a标签的id值
print(k['href'])#查a标签的href值
print(k.string)#查a标签的string
#tag.get('calss')，也可以达到这个效果
