问题描述
我已经研究了这个问题，但是还没有找到解决这个问题的实际方法.我正在将BeautifulSoup与Python结合使用，我想做的是从页面中获取所有图像标签，循环浏览每个图像标签，并检查每个图像标签的直接父级是否是锚标签.
I've researched this question but haven't seen an actual solution to solving this. I'm using BeautifulSoup with Python and what I'm looking to do is get all image tags from a page, loop through each and check each to see if it's immediate parent is an anchor tag.
这是一些伪代码:
html = BeautifulSoup(responseHtml)
for image in html.findAll('img'):
if (image.parent.name == 'a'):
image.hasParent = image.parent.link
对此有何想法?
推荐答案
您需要检查 name :
You need to check parent's name:
for img in soup.find_all('img'):
if img.parent.name == 'a':
print "Parent is a link"
演示:
>>> from bs4 import BeautifulSoup
>>>
>>> data = """
... <body>
... <a href="google.com"><img src="image.png"/></a>
... </body>
... """
>>> soup = BeautifulSoup(data)
>>> img = soup.img
>>>
>>> img.parent.name
a
您还可以使用img标签. rel ="noreferrer"> CSS选择器:
You can also retrieve the img tags that have a direct a parent using a CSS selector:
soup.select('a > img')
