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?
