如何使用 scrapy 从嵌入在 h2 下的标签中提取文本？

Question

我想从标签中提取名称。

response.css('h2.product-names::text').get()

但它正在返回：

<h2 class="product-names">

\<a target="\_blank" href="https://www.electronicsbazaar.com/dell-inspiron-13-7348-core-i5-5200u-2-20ghz-8gb-500gb-int-webcam-win-10-13-3-touch" title='Refurbished Dell Inspiron 13 7348 (Core I5 5Th Gen/8GB/500GB/Int/Win 10/13.3" Touch)'\>\n                                                                                                            Refurbished Dell Inspiron 13 7348 (Core I5 5Th Gen/8GB/500GB/Int/Win 10/13.3" Touch)                                                                                                                                          </a>

如何获取 link 的文本？

我试过了：

response.css('h2.product-names').get()

<h2 class="product-names">

\<a target="\_blank" href="https://www.electronicsbazaar.com/dell-inspiron-13-7348-core-i5-5200u-2-20ghz-8gb-500gb-int-webcam-win-10-13-3-touch" title='Refurbished Dell Inspiron 13 7348 (Core I5 5Th Gen/8GB/500GB/Int/Win 10/13.3" Touch)'\>\n                                                                                                            Refurbished Dell Inspiron 13 7348 (Core I5 5Th Gen/8GB/500GB/Int/Win 10/13.3" Touch)                                                                                                                                          </a>

问题是，如果我从你的屏幕截图中没看错的话，名称包含在标签中正确的 xpath 是：

response.xpath('//h2[@class="product-names"]/a/@title').extract()
