问题
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.
Here's some pseudo code:
html = BeautifulSoup(responseHtml)
for image in html.findAll('img'):
if (image.parent.name == 'a'):
image.hasParent = image.parent.link
Any ideas on this?
回答1:
You need to check parent's name:
for img in soup.find_all('img'):
if img.parent.name == 'a':
print "Parent is a link"
Demo:
>>> 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
You can also retrieve the img tags that have a direct a parent using a CSS selector:
soup.select('a > img')
