Clicking links with Python BeautifulSoup
Solution 1
So with help from the comments, I decided to just use urlopen like this:
from bs4 import BeautifulSoup
import urllib.request
import re
def getLinks(url):
html_page = urllib.request.urlopen(url)
soup = BeautifulSoup(html_page, "html.parser")
links = []
for link in soup.findAll('a', attrs={'href': re.compile("^http://")}):
links.append(link.get('href'))
return links
anchors = getLinks("http://madisonmemorial.org/")
for anchor in anchors:
happens = urllib.request.urlopen(anchor)
if happens.getcode() == "404":
# Do stuff
# Click on links and return responses
countMe = len(anchors)
for anchor in anchors:
i = getLinks(anchor)
countMe += len(i)
happens = urllib.request.urlopen(i)
if happens.getcode() == "404":
# Do some stuff
print(countMe)
I've got my own arguments in the if statements

Urlopen
is a better solution for your purpose but if you need to click and interact with elements on the web I suggest using selenium webdriver
. There are implementations for Java, Python, and other languages. I've used it with Java and Python, works pretty good. You can run it headless so the browser doesn't actually open.
pip install selenium

BeautifulSoup
is merely a DOM/HTML Parser, it doesn't constitute a real or in your case emulated browser. For that purpose you could use Chrome or Selenium to emulate a real browser and crawl freely, which gives you the advantage of handling Javascript, however when that's not needed, you can use the widely available package requests to recursively crawl all links:
for link in links:
body = requests.get(link).text

So I'm new to Python (I come from a PHP/JavaScript background), but I just wanted to write a quick script that crawled a website and all children pages to find all
a
tags withhref
attributes, count how many there are and then click the link. I can count all of the links, but I can't figure out how to "click" the links and then return the response codes.from bs4 import BeautifulSoup import urllib2 import re def getLinks(url): html_page = urllib2.urlopen(url) soup = BeautifulSoup(html_page, "html.parser") links = [] for link in soup.findAll('a', attrs={'href': re.compile("^http://")}): links.append(link.get('href')) return links anchors = getLinks("http://madisonmemorial.org/") # Click on links and return responses countMe = len(anchors) for anchor in anchors: i = getLinks(anchor) countMe += len(i) # Click on links and return responses print countMe
Is this even possible with
BeautifulSoup
?
Also, I'm not looking for exact code, all I'm really looking for is like a point in the right direction for function calls to use or something like that. Thanks!-
PRMoureu over 6 yearsi think you can't perform click actions with bs4, maybe take a look at selenium ? otherwise you can use
urllib2.urlopen
with the new links ? -
Vinícius Figueiredo over 6 yearsIf you want to click on them just to get the response code you can just use
urllib2.urlopen
with the url in hand

innicoder over 6 yearsI agree with everything above that the mister said, I'd also like to add that what the asker might be looking for is working with the
requests
library, you can make all kind of requests ( get/post / del and such ) with the mentioned lib. However, this can't be done for JS (at least in a manner that's known to me). But let's say you want to register or log in or submit data. All of this can be done only with usingrequests
orurllib
and much faster than Selenium. -
