Getting keywords from a web page via Nokogiri

Aug 29, 2013

A snippet.

In order to scrape the keywords from a web page using Nokigiri (to, for example, add to categories of a Jekyll page) is straight-forward, it turns out.

Script

require 'open-uri'
require 'nokogiri'

url="http://wiki.tamaratemple.com/"
content=Nokogiri::HTML(open(url))
keywords=content.search('//meta[@name="keywords"]').attr('content').value
puts keywords

Output

$ ruby keywords-from-url.rb
