Scrapy Spider Parser call function

[at4re]

How can I call the writeXML after my parser finish crawling data? Currently I can see the data crawl but don't see the output file. I tried to print under writeXML no output too. Below are my code:\[code\]class FriendSpider(BaseSpider): # identifies of the Spider name = "friend" count = 0 allowed_domains = ["example.com.us"] start_urls = [ "http://example.com.us/biz/friendlist/" ]def start_requests(self): for i in range(0,1722,40): yield self.make_requests_from_url("http://example.com.us/biz/friendlist/?start=%d" % i)def parse(self, response):response = response.replace(body=response.body.replace('<br />', '\n')) hxs = HtmlXPathSelector(response)sites = hxs.select('//ul/li')items = []for site in sites: item = Item() self.count += 1 item['id'] = str(self.count) item['name'] = site.select('.//div/div/h4/text()').extract() item['address'] = site.select('h4/span/text()').extract() item['review'] = ''.join(site.select('.//div[@class="review"]/p/text()').extract()) item['birthdate'] = site.select('.//div/div/h5/text()').extract() items.append(item)return itemsdef writeXML(self, items): root = ET.Element("Test") for item in items: item= ET.SubElement(root,'item') item.set('id', item['id']) address= ET.SubElement(item, 'address') address.text = item['address'] user = ET.SubElement(item, 'user') user.text = item['user'] birthdate= ET.SubElement(item, 'birthdate') birthdate.text = item['birthdate'] review = ET.SubElement(item, 'review') review.text = item['review'] # wrap it in an ElementTree instance, and save as XML file = open("out.xml", 'w') tree = ET.ElementTree(root) tree.write(file,xml_declaration=True,encoding='utf-8',method="xml")\[/code\]
