Tsumamigui（つまみぐい） is a simple and hussle-free Ruby web scraping library.

Ruby 2.1+

Add this line to your application's Gemfile:

gem 'tsumamigui'

Or install it yourself as:

$ gem install tsumamigui

You just give it a URL(or URLs) and Xpath to data you want to get with its label as a hash. Then you can get scraped and parsed data as array.

Tsumamigui.scrape('http://example.com', {h1: 'html/body/div/h1/text()'})

# Returns:
# [
#   {h1: 'Example Domain', scraped_from: 'http://example.com'}
# ]

You can specify multiple URLs if you want to scrape different pages which they have the same HTML structure.

urls = ['http://example.com/page/1', 'http://example.com/page/2']
Tsumamigui.scrape(urls, {h1: 'html/body/div/h1/text()'})

# Returns:
# [
#   {h1: 'Example Domain 1', scraped_from: 'http://example.com/page/1'}
#   {h1: 'Example Domain 2', scraped_from: 'http://example.com/page/2'}
# ]

Important: Tsumamigui requests each urls at intervals of 1.0~3.0sec automatically.

• Custom request headers.
