    rules = (
        Rule(
            SgmlLinkExtractor(allow_domains=("WEB_PAGE",)),
            callback='parse_page', follow=True
        ),
    )


    def parse_page(self, response):
      hxs = HtmlXPathSelector(response)
      print hxs
      sites = hxs.select('//title')
      items = []
      for s in sites:
      item = SpiderItem()
          item['title'] = s.select('//title').extract
          items.append(item)
