Nokogiri中的HTML元素之间的空格:: HTML#content

Question

当我跑这个

Nokogiri::HTML('<div class="content"><p>Hello</p><p>Good Sir</p></div>').content

我明白了

"HelloGood Sir"

有没有办法通过Nokogiri的API获得以下内容？

"Hello Good Sir"

Answer 1

require 'nokogiri'

doc = Nokogiri::HTML('<div class="content"><p>Hello</p><p>Good Sir</p></div>')

# below will fetch all text nodes irrespective of any tag,from the current document.
doc.xpath("//text()").map(&:text)
# => ["Hello", "Good Sir"]

doc.xpath("//text()").map(&:text).join(" ")
# => "Hello Good Sir"

# below will fetch all text nodes which are wrapped inside the p tag,
# from the current document.
doc.xpath("//p").map(&:text)
# => ["Hello", "Good Sir"]

doc.xpath("//p").map(&:text).join(" ")
# => "Hello Good Sir"
