I have created the following python file named test.py:
import scrapy
class EventsSpider(scrapy.Spider):
name = "test"
start_urls = [
'https://www.granteatrocc.com/programacion.php',
]
def parse(self, response):
print "\nBEFORE-------------------------------------------------\n"
scrapy.Request("https://stackoverflow.com/questions/6453269/jquery-select-element-by-xpath", callback=self.parse_two)
print "\nAFTER-------------------------------------------------\n"
def parse_two(self, response):
print "THIS IS WORKING"
And I Execute it using the following command:
scrapy runspider test.py
Obviously this example is a simplified version of a Crawler that must follow links to get extra fields. The output I get is the following. As you can see, the string "THIS IS WORKING" is never printed, so I understand that ````parse_two function is never called:
