xpath - Scrapy Amazon absolute path but with no value returned -


i trying use scrapy info amazon.co.uk using absolute path below. strangely no value returned. quite new scrapy:

scrapy shell http://www.amazon.co.uk/product-reviews/b0042eu3a2/  response.xpath('//*[@id="productreviews"]/tbody/tr/td[1]/a[1]/@name').extract()

i return name attribute in case is: ri4hgfjcsi04w.
