python scrapy extract data from website

I want to scrape data from this page. Here is my current code:

buf = cStringIO.StringIO()
c = pycurl.Curl()
c.setopt(c.URL, "http://www.guardalo.org/99407/")
c.setopt(c.VERBOSE, 0)
c.setopt(c.WRITEFUNCTION, buf.write)
c.setopt(c.CONNECTTIMEOUT, 15)
c.setopt(c.TIMEOUT, 15)
c.setopt(c.SSL_VERIFYPEER, 0)
c.setopt(c.SSL_VERIFYHOST, 0)
c.setopt(c.USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0')
c.perform()
body = buf.getvalue()
c.close()

response = HtmlResponse(url='http://www.guardalo.org/99407/', body=body)
print Selector(response=response).xpath('//edindex/text()').extract()

It works, but I need title, video link and description as separate variables. How can I achieve this?

Title can be extracted using //title/text(), video source link via //video/source/@src:

selector = Selector(response=response)

title = selector.xpath('//title/text()').extract()[0]
description = selector.xpath('//edindex/text()').extract()
video_sources = selector.xpath('//video/source/@src').extract()[0]

code_url = selector.xpath('//meta[@name="EdImage"]/@content').extract()[0]
code = re.search(r'(\w+)-play-small.jpg$', code_url).group(1)

print title
print description
print video_sources
print code

Prints:

No need for scrapy for a single-URL fetch -- just get that single page's HTML with a simpler tool (even simplest urllib.urlopen(theurl).read()!) then analyze the HTML e.g with BeautifulSoup. From a simple "view source" it looks like you're looking for:

<title>Best Babies Laughing Video Compilation 2012 [HD] - Guardalo</title>

(the title), one of the three:

<source src="http://static.guardalo.org/video_image/pre-roll-guardalo.mp4" type='video/mp4'>
<source src="http://static.guardalo.org/video_image/pre-roll-guardalo.webm" type='video/webm'>
<source src="http://static.guardalo.org/video_image/pre-roll-guardalo.ogv" type='video/ogg'>

(the video linkS, plural, and I can't pick one because you don't tell us which format[s] you prefer!-), and 

<meta name="description" content="Ciao a tutti amici di guardalo,quello che propongo oggi è un video sui neonati buffi con risate" />

(the description). BeautifulSoup makes it pretty trivial to get each one, e.g after the needed imports

html = urllib.urlopen('http://www.guardalo.org/99407/').read()
soup = BeautifulSoup(html)
title = soup.find('title').text

etc etc (but you'll have to pick one video link -- and I see in their sources they're mentioned as "pre-rolls" so it may be that the links to actual non-ads videos are in fact not on the page but only accessible after a log-in or whatever).
