本文实例讲述了Python使用scrapy抓取网站sitemap信息的方法。分享给大家供大家参考。具体如下：
import re from scrapy.spider import BaseSpider from scrapy import log from scrapy.utils.response import body_or_str from scrapy.http import Request from scrapy.selector import HtmlXPathSelector class SitemapSpider(BaseSpider): name = "SitemapSpider" start_urls = ["http://www.domain.com/sitemap.xml"] def parse(self, response): nodename = 'loc' text = body_or_str(response) r = re.compile(r"(<%s[s>])(.*"%(nodename,nodename),re.DOTALL) for match in r.finditer(text): url = match.group(2) yield Request(url, callback=self.parse_page) def parse_page(self, response): hxs = HtmlXPathSelector(response) #Mock Item blah = Item() #Do all your page parsing and selecting the elemtents you want blash.divText = hxs.select('//div/text()').extract()[0] yield blah
希望本文所述对大家的Python程序设计有所帮助。
