使用BeautifulSoup从img标签中提取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>

我想使用BeautifulSoup从图像(即img)标签中提取来源(即src)属性.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 want to extract the source (i.e. src) attribute from an image (i.e. img) tag using BeautifulSoup. 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 的 src 属性标签.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']
