使用BeautifulSoup从`img`标记中提取`src`属性 [英] Extract `src` attribute from `img` tag using BeautifulSoup

问题描述

<div class="someClass">
    <a href="href">
        <img alt="some" src="some"/>
    </a>
</div>

我使用bs4，但不能使用a.attrs['src']来获取src，但是可以获取href.我该怎么办?

I use bs4 and I cannot use a.attrs['src'] to get the src, but I can get href. What should I do?

推荐答案

您可以使用BeautifulSoup提取html img标记的src属性.在我的示例中，htmlText包含img标记本身，但是它也可以与urllib2一起用于URL.

You can use BeautifulSoup to extract src attribute of an html img tag. In my example, the htmlText contains the img tag itself but this can be used for a URL too along with urllib2.

对于网址

from BeautifulSoup import BeautifulSoup as BSHTML
import urllib2
page = urllib2.urlopen('http://www.youtube.com/')
soup = BSHTML(page)
images = soup.findAll('img')
for image in images:
    #print image source
    print image['src']
    #print alternate text
    print image['alt']

用于带有img标签的文本

from BeautifulSoup import BeautifulSoup as BSHTML
htmlText = """<img src="https://src1.com/" <img src="https://src2.com/" /> """
soup = BSHTML(htmlText)
images = soup.findAll('img')
for image in images:
    print image['src']
