Capybara.add_selector(:element) do
  xpath { |locator| "//*[normalize-space(text())=#{XPath::Expression::StringLiteral.new(locator)}]" }
end

When 'I click "$locator"' do |locator|
  msg = "No element found with the content of '#{locator}'"
  find(:element, locator, :message => msg).click
end

# Or a possible simplified alternative:
When 'I click "$locator"' do |locator|
  find(:xpath, XPath::HTML.content(locator)).click
end
