Grepping with Python - script/prog required.

[John Fitzsimons]

Hi,

I want to search an ordered text file and list web links such as :

Input like ;

A
Folder
Freeware
ftp://ftp.eunet.bg/pub/simtelnet
http://clients.net2000.com.au/~johnf/faq
Keywords:
Personal
Reach
Site
stuff
Toolbar
www.fourmilab.ch/annoyance-filter/

and Output like ;

ftp://ftp.eunet.bg/pub/simtelnet
http://clients.net2000.com.au/~johnf/faq
www.fourmilab.ch/annoyance-filter/

Can anyone suggest the code and/or a python program/script I could
adapt to do this please ?


Regards, John.

Hi Mike,

That's very dirty (with high false positive and negative hits) url
recognizer:

import re
url=re.compile(r'(?<=\s)(??:ftp|http|https)://|www(?:\.[^\. ]+){2,}).*?(?=
\s)')
print '\n'.join(re.findall(url, your_text_goes_here))

As I am a total newbie I will need to work out how to make that a
python file BUT as you have done the hard work it should be a lot
easier now.

It also looks like it might be close to being able to be used as a
regex string for something like NoteTab. Though, if using search and
replace, I would need to make it search for everything NOT matching
the above syntax and replace it with nothing.

I will also need to work out what "Closure cannot immediately follow
BegOfLine, EndOfLine or another closure" means, and fix it.

Many thanks for your help.


Regards, John.
