syntax error with nokogiri, unexpected '.' after nokogiri::CSS object
I just begin to learn scraping, and get the error " unexpected '.' after '#' ".
Using pry, when I put the line that causes this problem (i.e. page.css("div[@class='wrapper']/div/div//ul[17]/li[4]").text()), it works.
I tried to replace page.css("...") by page.xpath("...") but it doesn't return anything.
require "nokogiri"
require "open-uri"
require "pry"
page = Nokogiri::HTML(open("https://www.website_i_want_datas_from.com"))
myscrapp_2 =
for k in (1..500) do
((page.css("div[@class='wrapper']/div/div//ul[k]/li[4]").text() =~ /@/) != nil ? myscrapp_2 << page.css("div[@class='wrapper']/div/div//ul[k]/li[4]").text()
: myscrapp_2 << page.css("div[@class='wrapper']/div/div//ul[k]/li[5]").text())
binding.pry
end

I would rather use this kind of synthax to scrap elements :
scrap =
page.xpath('your/xpath').each do |node|
scrap.push(node.text)
end
