    <p>I'm currently trying to run the following code but it keeps scraping only the first result of each page. Any idea what the issue may be?</p> <pre><code>from scrapy.contrib.spiders import CrawlSpider, Rule from scrapy.contrib.linkextractors.sgml import SgmlLinkExtractor from scrapy.selector import HtmlXPathSelector from firstproject.items import xyz123Item import urlparse from scrapy.http.request import Request class MySpider(CrawlSpider): name = "xyz123" allowed_domains = ["www.xyz123.com.au"] start_urls = ["http://www.xyz123.com.au/",] rules = (Rule (SgmlLinkExtractor(allow=("",),restrict_xpaths=('//*[@id="1234headerPagination_hlNextLink"]',)) , callback="parse_xyz", follow=True), ) def parse_xyz(self, response): hxs = HtmlXPathSelector(response) xyz = hxs.select('//div[@id="1234SearchResults"]//div/h2') items = [] for xyz in xyz: item = xyz123Item() item ["title"] = xyz.select('a/text()').extract()[0] item ["link"] = xyz.select('a/@href').extract()[0] items.append(item) return items </code></pre> <p>The Basespider version works well scraping ALL the required data on the first page: </p> <pre><code>from scrapy.spider import BaseSpider from scrapy.selector import HtmlXPathSelector from firstproject.items import xyz123 class MySpider(BaseSpider): name = "xyz123test" allowed_domains = ["xyz123.com.au"] start_urls = ["http://www.xyz123.com.au/"] def parse(self, response): hxs = HtmlXPathSelector(response) titles = hxs.select('//div[@id="1234SearchResults"]//div/h2') items = [] for titles in titles: item = xyz123Item() item ["title"] = titles.select("a/text()").extract() item ["link"] = titles.select("a/@href").extract() items.append(item) return items </code></pre> <p>Sorry for the censoring. I had to censor the website for privacy reasons.</p> <p>The first code crawls through the pages well the way I'd like it to crawl, however it only pulls the first item title and link. NOTE: The XPath of the first title using "inspect element" in google is:<br> <code>//*[@id="xyz123SearchResults"]/div[1]/h2/a</code>,<br> second is <code>//*[@id="xyz123SearchResults"]/div[2]/h2/a</code> <br> third is <code>//*[@id="xyz123SearchResults"]/div[3]/h2/a</code> etc.</p> <p>I'm not sure if the div[n] bit is what's killing it. I'm hoping it's an easy fix.</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
