In regards to: Find Hyperlinks in Text using Python (twitter related)
How can I extract just the url so I can put it into a list/array?
Let me clarify, I don't want to parse the URL into pieces. I want to extract the URL from the text of the string to put it into an array. Thanks!
In response to the OP's edit I hijacked Find Hyperlinks in Text using Python (twitter related) and came up with this:
import re
myString = "This is my tweet check it out http://example.com/blah"
print(re.search("(?P<url>https?://[^\s]+)", myString).group("url"))
Misunderstood question:
>>> from urllib.parse import urlparse
>>> urlparse('http://www.ggogle.com/test?t')
ParseResult(scheme='http', netloc='www.ggogle.com', path='/test',
params='', query='t', fragment='')
>>> from urlparse import urlparse
>>> urlparse('http://www.cwi.nl:80/%7Eguido/Python.html')
ParseResult(scheme='http', netloc='www.cwi.nl:80', path='/%7Eguido/Python.html',
params='', query='', fragment='')
ETA: regex are indeed are the best option here:
>>> s = 'This is my tweet check it out http://tinyurl.com/blah and http://blabla.com'
>>> re.findall(r'(https?://\S+)', s)
['http://tinyurl.com/blah', 'http://blabla.com']
You can use the following monstrous regex:
\b((?:https?://)?(?:(?:www\.)?(?:[\da-z\.-]+)\.(?:[a-z]{2,6})|(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)|(?:(?:[0-9a-fA-F]{1,4}:){7,7}[0-9a-fA-F]{1,4}|(?:[0-9a-fA-F]{1,4}:){1,7}:|(?:[0-9a-fA-F]{1,4}:){1,6}:[0-9a-fA-F]{1,4}|(?:[0-9a-fA-F]{1,4}:){1,5}(?::[0-9a-fA-F]{1,4}){1,2}|(?:[0-9a-fA-F]{1,4}:){1,4}(?::[0-9a-fA-F]{1,4}){1,3}|(?:[0-9a-fA-F]{1,4}:){1,3}(?::[0-9a-fA-F]{1,4}){1,4}|(?:[0-9a-fA-F]{1,4}:){1,2}(?::[0-9a-fA-F]{1,4}){1,5}|[0-9a-fA-F]{1,4}:(?:(?::[0-9a-fA-F]{1,4}){1,6})|:(?:(?::[0-9a-fA-F]{1,4}){1,7}|:)|fe80:(?::[0-9a-fA-F]{0,4}){0,4}%[0-9a-zA-Z]{1,}|::(?:ffff(?::0{1,4}){0,1}:){0,1}(?:(?:25[0-5]|(?:2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(?:25[0-5]|(?:2[0-4]|1{0,1}[0-9]){0,1}[0-9])|(?:[0-9a-fA-F]{1,4}:){1,4}:(?:(?:25[0-5]|(?:2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(?:25[0-5]|(?:2[0-4]|1{0,1}[0-9]){0,1}[0-9])))(?::[0-9]{1,4}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-5])?(?:/[\w\.-]*)*/?)\b

I call that file urlmarker.py and when I need it I just import it, eg.
import urlmarker
import re
re.findall(urlmarker.URL_REGEX,'some text news.yahoo.com more text')
cf. http://daringfireball.net/2010/07/improved_regex_for_matching_urls and What's the cleanest way to extract URLs from a string using Python?
If you want to extract URLs from any text you can use my urlextract. It finds URL based on TLD found in text. It expands to both side from TLD position an gets whole URL. Its easy to use. Check it: https://github.com/lipoja/URLExtract
from urlextract import URLExtract
extractor = URLExtract()
urls = extractor.find_urls("Text with URLs: stackoverflow.com.")
Don't forget to check for whether the search returns a value of None—I found the posts above helpful but wasted time dealing with a None result.
See Python Regex "object has no attribute".
i.e.
import re
myString = "This is my tweet check it out http://tinyurl.com/blah"
match = re.search("(?P<url>https?://[^\s]+)", myString)
if match is not None:
print match.group("url")
Regarding this:
import re
myString = "This is my tweet check it out http:// tinyurl.com/blah"
print re.search("(?P<url>https?://[^\s]+)", myString).group("url")
It won't work well if you have multiple urls in the string. If the string looks like:
myString = "This is my tweet check it out http:// tinyurl.com/blah and http:// blabla.com"
You may do something like this:
myString_list = [item for item in myString.split(" ")]
for item in myString_list:
try:
print re.search("(?P<url>https?://[^\s]+)", item).group("url")
except:
pass
Simply follow below code and enjoy....!!!!
import requests
from bs4 import BeautifulSoup
url = "your url"//Any url that you want to fetch.
r = requests.get(url)
htmlContent = r.content
soup = BeautifulSoup(htmlContent, 'html.parser')
anchors = soup.find_all('a')
all_links = set()
for link in anchors:
if(link.get('href') != '#'):
linkText = url+str(link.get('href'))
all_links.add(link)
print(linkText)
In case of extracting from HTML source:
from urlextract import URLExtract
from requests import get
url = "sample.com/samplepage/"
req = requests.get(url)
text = req.text
# or if you already have the html source:
# text2 = "This is html for ex <a href='http://google.com/'>Google</a> <a href='http://yahoo.com/'>Yahoo</a>"
text = text.replace(' ', '').replace('=','')
extractor = URLExtract()
print(extractor.find_urls(text))
output (text2):
['http://google.com/', 'http://yahoo.com/']
