Scrapy "parse" 函数未执行

Question

我在Ubuntu 11上开始使用scrapy，但遇到了一些问题。具体来说，下面代码中的解析函数没有执行，尽管终端显示爬虫已经成功运行并关闭了。

from scrapy.contrib.spiders import CrawlSpider
from scrapy.selector import HtmlXPathSelector



class myTestSpider(CrawlSpider):
    name="go4mumbai.com"
    domain_name = "go4mumbai.com"
    start_urls = ["http://www.go4mumbai.com/Mumbai_Bus_Route.php?busno=1"]

def parse(self, response):  
    hxs = HtmlXPathSelector(response)
    stopNames=hxs.select('//table[@cellspacing="2"]/tr/td[2]/a/text()').extract()
    print len(stopNames)

SPIDER = myTestSpider()

以下是终端的响应信息：

我是不是漏掉了代码的某个部分？请给点建议..

你的 parse() 函数好像没有放在你的爬虫类里面。把整个函数往右缩进一个位置，这样它就属于这个类了，就能被调用了。
