I would like to extract the URL from an xpath using the requests package in python. I can get the text but nothing I try gives the URL. Can anyone help?
ipdb> webpage.xpath(xpath_url + '/text()')
['Text of the URL']
ipdb> webpage.xpath(xpath_url + '/a()')
*** lxml.etree.XPathEvalError: Invalid expression
ipdb> webpage.xpath(xpath_url + '/href()')
*** lxml.etree.XPathEvalError: Invalid expression
ipdb> webpage.xpath(xpath_url + '/url()')
*** lxml.etree.XPathEvalError: Invalid expression
I used this tutorial to get started: http://docs.python-guide.org/en/latest/scenarios/scrape/
It seems like it should be easy, but nothing comes up during my searching.
Thank you.
Have you tried webpage.xpath(xpath_url + '/@href')
?
Here is the full code:
from lxml import html
import requests
page = requests.get('http://econpy.pythonanywhere.com/ex/001.html')
webpage = html.fromstring(page.content)
webpage.xpath('//a/@href')
The result should be:
[
'http://econpy.pythonanywhere.com/ex/002.html',
'http://econpy.pythonanywhere.com/ex/003.html',
'http://econpy.pythonanywhere.com/ex/004.html',
'http://econpy.pythonanywhere.com/ex/005.html'
]
You would be better served using BeautifulSoup :
from bs4 import BeautifulSoup
html = requests.get('testurl.com')
soup = BeautifulSoup(html, "lxml") # lxml is just the parser for reading the html
soup.find_all('a href') # this is the line that does what you want
You can print that line, add it to lists, etc. To iterate through it, use:
links = soup.find_all('a href')
for link in links:
print(link)
with the benefits of a context manager:
with requests_html.HTMLSession() as s:
try:
r = s.get('http://econpy.pythonanywhere.com/ex/001.html')
links = r.html.links
for link in links:
print(link)
except:
pass
You can do it easily with selenium.
link = webpage.find_elemnt_by_xpath(*xpath url to element with link)
url = link.get_attribute('href')
from requests_html import HTMLSession
session = HTMLSession()
r = session.get('https://www.***.com')
r.html.links
