Mixing
Xpath from next page to scrapy in Stack Overflow
I'm trying to crawl Stack Overflow with scrapy, but I'm not clear enough to make the rule to get next page. I don't know if the XPath I choose is right also.
He follows the code:
class StackCrawlerSpider(CrawlSpider):
name = 'stack_crawler'
allowed_domains = ['stackoverflow.com']
start_urls = [
'http://stackoverflow.com/questions?pagesize=50&sort=newest'
]
rules = [
Rule(LinkExtractor(allow=(), restrict_xpaths=('div[@class="pager fl"]/a[@class="page-numbers next"]/@href',)),
callback='parse_item', follow=True)
]
Could someone who understand scrapy an XPath help me to get next page from the following page (http://stackoverflow.com/questions?pagesize=50&sort=newest) and add it to the rule?

you need to select root element // then go to span containing class page-numbers next and text next then go to it parent .. which is a tag.
//span[@class="page-numbers next"]/../@href

Wouldn't it be simpler to use//a[@rel="next"]/@href?
