我有这个简单的HTML:

<div> Test <span> someting </span></div>

我怎样才能只检索innertextdiv的？

使用text检索div中的所有文本:

[1] pry(#<SandBox>)> first(:xpath, '//div').text
=> "Test someting"

使用text()在我下面的错误XPath查询的结果:

[2] pry(#<SandBox>)> first(:xpath, '//div/text()')
Capybara::Poltergeist::BrowserError: There was an error inside the PhantomJS portion of Poltergeist. This is probably a bug, so please report it. 
TypeError: 'null' is not an object (evaluating 'window.getComputedStyle(element).display')

但是,使用与Nokogiri相同的XPath工作:

[3] pry(#<SandBox>)> Nokogiri::HTML(page.html).xpath('//div/text()').text
=> " Test "

有没有办法只使用水豚而不诉诸Nokogiri？
