I am learning Scrapy with the nice
tutorial: http://doc.scrapy.org/en/1.0/intro/tutorial.html
I have one question when I run the following. The result I got in the line `
sel.xpath('a/text()').extract()` inside the loop is a list with one string
rather than just a string. As we are already looping throught response.xpath
('//ul/li') why do I still have a list?
```
import scrapy
class DmozSpider(scrapy.Spider):
name = "dmoz"
allowed_domains = ["dmoz.org"]
start_urls = [
"http://www.dmoz.org/Computers/Programming/Languages/Python/Books/";,
"http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/";
]
def parse(self, response):
for sel in response.xpath('//ul/li'):
title = sel.xpath('a/text()').extract()
link = sel.xpath('a/@href').extract()
desc = sel.xpath('text()').extract()
print title, link, desc
```
