How to get a png file from a website using lxml?

Question

Python

The site has such a block with such a png file, how can I get it (download)?

<div class="reader-view" data-p="2">
   <img src="https://img4.example.me//example1/example2/examples/8-37/02.png">
</div>

If you know how to solve it, please explain the code a little, I still want to understand what's what.

Answer 1

from lxml import html
lxml_string = '''<div class="reader-view" data-p="2">
   <img src="https://upload.wikimedia.org/wikipedia/commons/thumb/4/47/PNG_transparency_demonstration_1.png/274px-PNG_transparency_demonstration_1.png">
</div>'''
tree = html.document_fromstring(lxml_string)
pic_path = tree.xpath('//img/@src')[0]

import requests

r = requests.get(pic_path, allow_redirects=True)
open('d:\\02.png', 'wb').write(r.content)

1. To download the file, use requests
lib 2. To parse html, use lxml.html
3. After that, using xpath technology, we find the required src attribute in the img nodes, take zero from everything found - specifically for this example
