InvalidSchema("No connection adapters were found for '%s'" % url)

Question

I was able to gather data from a web page using this

import requests
import lxml.html
import re
url = "http://animesora.com/flying-witch-episode-7-english-subtitle/"
r = requests.get(url)
page = r.content
dom =  lxml.html.fromstring(page)

for link in dom.xpath('//div[@class="downloadarea"]//a/@href'):
    down = re.findall('https://.*',link)     
    print (down)

when I try this to gather more data on the results of the above code I was presented with this error:

Traceback (most recent call last):
  File "/home/sven/PycharmProjects/untitled1/.idea/test4.py", line 21, in <module>

This is the code I was using:

for link2 in down:
    r2 = requests.get(down)
    page2 = r.url
    dom2 = lxml.html.fromstring(page2)

for link2 in dom2('//div[@class="button green"]//onclick'):

    down2 = re.findall('.*',down2)
    print (down2)

Answer 1

You are passing in the whole list :

for link2 in down:
    r2 = requests.get(down)

Note how you passed in down , not link2 . down is a list, not a single URL string.

Pass in link2 :

for link2 in down:
    r2 = requests.get(link2)

I'm not sure why you are using regular expressions. In the loop

for link in dom.xpath('//div[@class="downloadarea"]//a/@href'):

each link is already a fully qualified URL:

>>> for link in dom.xpath('//div[@class="downloadarea"]//a/@href'):
...     print link

You don't need to do any further processing on that.

Your remaining code has more errors; you confused r2.url with r2.content , and forgot the .xpath part in your dom2.xpath(...) query.
