Documentation

webgrep is a simple tool for scraping websites from the command line

Setup:
> sudo easy_install webgrep 



Example:
Finding number of ratings for a book on goodreads

Find the location of the 'Ratings' in the html by using the -g option:
> webgrep.py -g 'Ratings' -u "http://www.goodreads.com/book/show/4588.Extremely_Loud_and_Incredibly_Close"
match,location
"267,896 Ratings"," 1,3,1,3,5,3,7,1,3,5,14,1,0"

Now use that location value (" 1,3,1,3,5,3,7,1,3,5,14,1,0") as the -l argument to look in the same location on a different page
> webgrep.py -l " 1,3,1,3,5,3,7,1,3,5,14,1,0" -u "http://www.goodreads.com/book/show/1618.The_Curious_Incident_of_the_Dog_in_the_Night_Time"
"778,683 Ratings"





Example:
Using "-" in a location value as a wildcard. Want to find all imdb titles on a page

> webgrep.py  -g Shawshank -u "http://www.imdb.com/search/title?num_votes=50000,&release_date=1990,&sort=user_rating,desc&title_type=feature"
match,location
The Shawshank Redemption," 1,3,3,1,14,12,3,5,3,5,3,0"


> webgrep.py  -g "The Dark Knight" -u "http://www.imdb.com/search/title?num_votes=50000,&release_date=1990,&sort=user_rating,desc&title_type=feature"
match,location
The Dark Knight," 1,3,3,1,14,12,3,5,5,5,3,0"
The Dark Knight Rises," 1,3,3,1,14,12,3,5,69,5,3,0"

Common errors:
Quote the -u argument in bash or else '&' may be read as running the process in the background instead of part of the url
