hello,
From past few days I'm trying to develop a regex that fetch all the
external links from the web pages given to it using grep.
Here is my grep command
grep -h -o -e "\(\(mailto:\|\(\(ht\|f\)tp\(s\?\)\)\)\://\)\{1\}\(.*\?\)" "/mnt/websites_folder/folder_to_search" -r
now the grep seem to return everything after the
external links in that given line
Example
if an html file contain something like this on same line
GoogleYahoo
then the given grep command return the following result
http://www.google.com">Google</a><p><a href='https://yahoo.com'>Yahoo</a></p>
the idea here is that if an html file contain more than one links(`irrespective in a,img etc`) in same line then the regex should fetch only the links and not all content of that line
I managed to developed the same in rubular.com
the regex is as follow
("|')(\b((ht|f)tps?:\/\/)(.*?)\b)("|')
with work with the above input
but iam not able to replicate the same in grep
can anyone help
I can't modify the html file so don't ask me to do that neither I can look for each specific tags and check their attributes to to get
external links as it addup processing time and my application doesn't demand that
Thank You
