ruby - How to parse attribute and value of a tag in html file at same time with Nokogori? -

say have html file called ex.html following:

<ul>     <li data-value="datav1">val1</li>     <li data-value="datav2">val2</li>     <li data-value="datav3">val3</li> </ul> 

i want extract attribute data-value , text value line line , output result below:

datav1:val1

datav2:val2

datav3:val3

however i'm new nokogori, know code below,which can extract attribute data-value, , don't know how extract attribute , text value in same loop.

require 'nokogiri' page_temp = nokogiri::html(open("ex.html")) page_temp.xpath('//li/@data-value').each |node|     puts node end 

i'd appreciate if can teach me how make work through nokogori, , better if there other solution using shell script.

update

thanks @rajarshi das , @arun kumar, answers partly solved problem. problem node.text chinese characters. , unrecognizable when print them out in terminal. tried print out page_temp when after executed page_temp = nokogiri::html(open("ex.html")) , find chinese characters €. guess read ex.html file wrong in ruby.

this should it.

page_temp.xpath('//li').each |node|   puts "#{node['data-value']}:#{node.text}" end 

the code self-explanatory let me explain. you're looping on li elements , printing value of data-value attribute along text contained in li element.
