I use xpath to extract text. My code is

class itcast(scrapy.Spider):
    name = 'SH'
    allowd_domains = ["http://sh.centanet.com/"]
    start_urls = ["http://sh.centanet.com/zufang/p2/"]

    def parse(self,response):
        
        list = response.xpath("//p[@class='//p[@class='ouse-item clearfix house-item-curr']")
        
        for i in list:
            name = i.xpath("//a[@class='cBlueB'.text()]")
            print name[0]

I can find this category
The error reported is in the line for i in list:
name =f.xpath(), the text cannot be extracted.
The execution code cannot be found. Please help me find out what is wrong with me. I have tried similar things many times. I have no choice but to ask questions. I hope you can answer them. Thank you!

Answer 1

def parse(response):
    list = response.xpath("//p[@class='house-item clearfix house-item-curr']")

    for i in list:
        name = i.xpath("//a[@class='cBlueB']")
        print name[0].text

Maybe that’s what you mean?

Answer 2

name = i.xpath("//a[@class='cBlueB'.text()]") is wrong. How can text be placed inside []
