          It is recommended that you use xpath expressions. For your example response.xpath("//a[class='aok-block aok-nowrap']").get_attribute('href')

            Will be:



                response.xpath('*//a/@href').extract_first()
            response.xpath('*//a/@class').extract_first()
            response.xpath('*//a/@title').extract_first()


            If you want get only href then you must find upper tag...like this:



                <li>
            <a id="nav-questions" href="/questions">
            </li>


            Will be:



                response.xpath('...some uniq selector.../li/a/@href').extract_first()
