Python regular expression to get URL

advertisements

I am trying to get a URL out of a long string and I am unsure how write the regex;

$ string = '192.00.00.00 - WWW.WEBSITE.COM GET /random/url/link'

I am trying to use the 're.search' function in order to pull out the WWW.WEBSITE.COM only without spaces. I would like it look like this;

$ get_site = re.search(regex).group()

$ print get_site

$ WWW.WEBSITE.COM

BUT they will all be in between a (-) and the (GET)

That is all the information you need:

>>> import re
>>> string = '192.00.00.00 - WWW.WEBSITE.COM GET /random/url/link'
>>> re.search('-\s+(.+?)\s+GET', string).group(1)
'WWW.WEBSITE.COM'
>>>

Below is a breakdown of what the Regex pattern is matching:

-      # -
\s+    # One or more spaces
(.+?)  # A capture group for one or more characters
\s+    # One or more spaces
GET    # GET

Note too that .group(1) gets the text captured by (.+?). .group() would return the entire match:

>>> re.search('-\s+(.+?)\s+GET', string).group()
'- WWW.WEBSITE.COM GET'
>>>
