python - Scrapy: how to follow multiple links on a page using regex -


i have scraper collects information perfectly, when try implement rules crawl "next" page stuck. using scrapy 0.22 (i can't upgrade @ time).

import re import datetime import dateutil  import urllib2  scrapy.http import request scrapy.selector import selector scrapy.contrib.linkextractors.sgml import sgmllinkextractor scrapy.contrib.spiders import crawlspider, rule crawlers.spiders import basecrawler   class rappspider(basecrawler):     name = "rapp"      base_url = "www.example.com"     start_urls = [         # "http://www.example.com/news-perspective",         # "http://www.example.com/news-perspective?f[0]=field_related_topics%3a31366",         "http://www.example/news-perspective?key=&page=%d"      ]     # rules = [          # rule(sgmllinkextractor(allow=r'?key=&page=[0-9]'), callback='get_article_links', follow= true)      # ]      title_xpath_selector= "//div[@id='inset-content']//h1/text()"      text_xpath_selector = "//div[@class='field-item even']/p/text()"      datetime_xpath_selector = "//div[@class='field-items']/div/span/text()"      def get_article_links(self, response, *args, **kwargs):         html = selector(response)         link_extractor = sgmllinkextractor(allow=('http://www.example.com/news-perspective/\d{4}/\d{2}\/*\s*$',))          is_relative_path = false         yield [link.url link in link_extractor.extract_links(response)], is_relative_path

the scraper works start_urls http://www.example/news-perspective lists number of articles on page, scraper follow links defined get_article_links , relevant information. however, i'd able go next page (same format on other pages, url being

http://www.example/news-perspective?key=&page=#

how can set existing code? need 2 separate rules ? or need alter start_requests?
