Scraping data from multiple URL

Question

I wish to scrape data from [a link] http://cbfcindia.gov.in/html/SearchDetails.aspx?mid=1&Loc=Backlog ! , However the MID parameter is incremental in URL to give 2nd, 3rd URL ..... till 1000 URLs, so how shall I deal with this(I am new to PYTHON AND SCRAPY, so dont mind me asking this)?

Please check the XPATH i have used to extract the information, it is fetching no output, is there elementary error in the spider

from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from movie.items import MovieItem

class MySpider(BaseSpider):
    name = 'movie'
    allowed_domains= ["http://cbfcindia.gov.in/"]
    start_urls = ["http://cbfcindia.gov.in/html/SearchDetails.aspx?mid=1&Loc=Backlog"]

    def parse(self, response):
        hxs = HtmlXPathSelector(response)
        titles = hxs.select("//body")    #Check
        print titles
        items = []
        for titles in titles:
          print "in FOR loop"
          item = MovieItem()
                  item ["movie_name"]=hxs.xpath('//TABLE[@id="Table2"]/TR[2]/TD[2]/text()').extract()
          print "XXXXXXXXXXXXXXXXXXXXXXXXX  movie name:", item["movie_name"]
          item ["movie_language"] = hxs.xpath('//*[@id="lblLanguage"]/text()').extract()
          item ["movie_category"] = hxs.xpath('//*[@id="lblRegion"]/text()').extract()
          item ["regional_office"] = hxs.xpath('//*[@id="lblCertNo"]/text()').extract()
          item ["certificate_no"] = hxs.xpath('//*[@id="Label1"]/text()').extract()
          item ["certificate_date"] = hxs.xpath('//*@id="lblCertificateLength"]/text()').extract()
          item ["length"] = hxs.xpath('//*[@id="lblProducer"]/text()').extract()
          item ["producer_name"] = hxs.xpath('//*[@id="lblProducer"]/text()').extract()

          items.append(item)

          print "this is ITEMS"
        return items

Below is the log :

Answer 1

In addition to @Talvalin's answer, the correct XPath should be of the form:

item["movie_name"] = hxs.xpath("//*[@id='lblMovieName']/font/text()").extract()

For some reason, when the page loads, the <font> tag get separated from the <span> tag (or whatever tag the id is in). I've tested this and it works.

Word of warning, though: the site is pretty much protected from scraping. I've tried running a second scrape and it immediately threw a Runtime Error .

Answer 2

Allowed domains should be defined without the http:// . For example:

allowed_domains= ["cbfcindia.gov.in/"]

If any issues persist, then please show the full log that includes details of the pages crawled and any redirects that may have occurred.
