Hi there ,
Sir their isn't any generic extractor which can extract all the website. As each website has different structure so we have to design extractor on the basis of the websites.
We are proficient in data extraction , web scraping and crawling services. Please come up with the link so I can optimize that how long it will take to write a extraction script for you.
I am really interested to discuss this project with you.
Thanks and Regards,
Sheeraz Shah
