Get link and href text from html doc with Nokogiri & Ruby?

Question

I\'m trying to use the nokogiri gem to extract all the urls on the page as well their link text and store the link text and url in a hash.

    &         


        

Answer 1

Here's a one-liner:

Hash[doc.xpath('//a[@href]').map {|link| [link.text.strip, link["href"]]}]

#=> {"Foo"=>"#foo", "Bar"=>"#bar"}

Split up a bit to be arguably more readable:

h = {}
doc.xpath('//a[@href]').each do |link|
  h[link.text.strip] = link['href']
end
puts h

#=> {"Foo"=>"#foo", "Bar"=>"#bar"}
