Small white just learning scrapy, encounter a problem, don't understand, ask for help:
Simply write a crawler, visit scrapy official tutorial page, all the author want to extract the home page, the HTML code is as follows:

 import scrapy 

The class Quote_Spider (scrapy. Spiders) : 
Name='quotes' 
Allowed_domains=[' http://quotes.toscrape.com/'] 
Start_urls=[' http://quotes.toscrape.com/'] 

Def parse (self, response) : 
The content=response. Xpath ("//div [@ class='col - md - 8] ") 
Print (" 8 "* 30) 
Print (content [0]. Extract ()) 
Print (' * '* 30) 
Print (content [0]. Xpath ("//div//small/text () "). The extract ()) 

The content list should include two selector, and one of the content of the authors extract [0] does not contain elements, content [1] is contained and can successfully extracted, then why the content [0] does not contain the author element, obviously I can filter out,,,,,, crazy, and execute the following screenshot:
