Ruby, Nokogiri: Get the element name of the selected node


In Nokogiri, you can select a node by specifying the element name with css or at_css, but on the contrary, I was wondering how to get the element name from the selected node, so I checked it. ..

use the name method

Getting the element name of a node is very simple. Suppose you have the following html file.


    <meta charset="UTF-8">

Select the p tag in at_css.


require 'nokogiri'

html = open('hello_utf8.html').read
doc = Nokogiri::HTML.parse(html)

element = doc.at_css('p')

p  #=> 'p'
p  #=> 'body'

You can also use parent etc. to select another node and get the element name.

at the end

Normally, the html structure is first looked at and then scraped, so I don't think there is much demand for getting the element name from the node ^^;
