motion-html

Parse and traverse HTML in your RubyMotion app. It's like Nokogiri for RubyMotion!

motion-html uses HTMLKit under the hood.

Currently, only iOS and OS X are supported.

Installation

Add this line to your application's Gemfile:

gem 'motion-html', '~> 2.0'

And then execute:

$ bundle && rake pod:install

Usage

Initialize a new document:

doc = Motion::HTML::Doc.new(html)
# or simply:
doc = HTML.parse(html)

Then query using CSS3 selectors to find one or an array of elements:

array_of_links = doc.all('.photos li a')
first_li = doc.first('.photos li')
element = doc.find('#one-and-only')

Each item returned from a query will be an Element object. You can then access attributes or text content:

links = doc.all('.photos li a')
links.each do |el|
  puts "Link tag: " + el.tag
  puts "Link text: " + el.text
  puts "Link URL: " + el['href']
  puts "Link attributes: " + el.attributes.inspect
end

With an Element, you can traverse to its parent, children, or next sibling:

first_list_item = doc.first('.photos li')
unordered_list = first_list_item.parent
links = first_list_item.children
second_list_item = first_list_item.next_sibling

See the main_spec.rb file for more examples.
