XPath

If the provided DOM navigation syntax does not provide a way for you to definitively select the required element, XPath is available via the #xpath method which delegates directly to the underlying Nokogiri::HTML::Document object.

subject(:document) do
  parse_html('<table><tr><td>My content</td></table>')
end

it 'matches using xpath' do
  expect(document.xpath('//table/tr/td').text).to eql 'My content'
end
