Get href using css selector with Scrapy

What you're looking for is:

Link = Link1.css('span[class=title] a::attr(href)').extract()[0]

Since you're matching a span "class" attribute also, you can even write

Link = Link1.css('span.title a::attr(href)').extract()[0]

Please note that ::text pseudo element and ::attr(attributename) functional pseudo element are NOT standard CSS3 selectors. They're extensions to CSS selectors in Scrapy 0.20.

Edit (2017-07-20): starting from Scrapy 1.0, you can use .extract_first() instead of .extract()[0]

Link = Link1.css('span[class=title] a::attr(href)').extract_first()
Link = Link1.css('span.title a::attr(href)').extract_first()

Link = Link1.css('span.title a::attr(href)').extract_first()
