"我是数据爬取的新手，正在学习如何操作。我打算从这个网站 https://www.twhouse.co.uk/index.php?route=product/catalog 中提取数据数值，我正在使用 Scrapy Shell 进行查询和组装我的爬虫。当我执行 response.css('div.caption span.stat-1').get() 时，我得到了以下结果：<span class="stat-1"><span class="stats-label">SKU:</span> <span>8644</span></span>。我想提取 SKU 的值。谢谢大家的支持。

在 Scrapy Shell 中，我想查询网址 https://www.twhouse.co.uk/index.php?route=product/catalog，执行 response.css('div.caption span.stat-1').get() 后，我得到了以下结果：<span class="stat-1"><span class="stats-label">SKU:</span> <span>8644</span></span>。我只想要这个中的 SKU 值。当我尝试改成 response.css('div.caption span.stats-label').get() 时，我得到了这个结果 <span class="stats-label">SKU:</span>，当我加入 '::text' 时，即 response.css('div.caption span.stats-label::text').get()，我得到了响应 'SKU:'，而不是 SKU 的值。我该如何获取值？"

以下是翻译好的内容：

HTML如下：

...
...
<span class="stat-1">
    <span class="stats-label">SKU:</span>
    <span>8811</span>
</span>
...
...

所以你想要获取外部span标签（"stat-1"）内的第二（最后一个）span标签。

Python代码如下：

scrapy shell https://www.twhouse.co.uk/index.php?route=product/catalog

>>> response.css('div.caption span.stat-1 span:last-child::text').get()
'8811'

如果你想要获取所有的文本，你可以使用 getall()，这样你会得到一个列表。

scrapy shell https://www.twhouse.co.uk/index.php?route=product/catalog

>>> response.css('div.caption span.stat-1 span:last-child::text').getall()
['8811', '8943', '8939', '8730', '8853', '8748', '8901', '8756', '8855', '8951', '8838', '8857', '8934', '8856', '8924', '9050', '8862', '8863', '8764', '9047', '9045', '9055', '8746', '8814', '8714', '8760', '8944', '8958', '8959', '8722', '8743', '8785', '8946', '8860', '8877', '8715', '9011', '8945', '9023', '8947', '9015', '8777', '8753', '8797', '8899', '8734', '8705', '9042', '8936', '8787', '8950', '8888', '8723', '9018', '9019', '8948', '8942', '8890', '8969', '8906', '8907', '8960', '9021', '8713', '9009', '9014', '9022', '8831', '8707', '8724', '9033', '9024', '9038', '8829', '9034', '9027', '9025', '9031', '9026', '9029', '9030', '9032', '9041', '9039', '9051', '9028', '8994', '8765', '8977', '8808', '8978', '8809', '8876', '9008', '8883', '8768', '8823', '8740', '8873', '9013']
英文:

The HTML looks like this:

...
...
&lt;span class=&quot;stat-1&quot;&gt;
    &lt;span class=&quot;stats-label&quot;&gt;SKU:&lt;/span&gt;
    &lt;span&gt;8811&lt;/span&gt;
&lt;/span&gt;
...
...

So you want to get the second (last) span tag inside the outer span tag ("stat-1").

scrapy shell https://www.twhouse.co.uk/index.php?route=product/catalog

&gt;&gt;&gt; response.css(&#39;div.caption span.stat-1 span:last-child::text&#39;).get()
&#39;8811&#39;

If you want to get all the text you can use getall() and you'll get them as a list.

scrapy shell https://www.twhouse.co.uk/index.php?route=product/catalog

&gt;&gt;&gt; response.css(&#39;div.caption span.stat-1 span:last-child::text&#39;).getall()
[&#39;8811&#39;, &#39;8943&#39;, &#39;8939&#39;, &#39;8730&#39;, &#39;8853&#39;, &#39;8748&#39;, &#39;8901&#39;, &#39;8756&#39;, &#39;8855&#39;, &#39;8951&#39;, &#39;8838&#39;, &#39;8857&#39;, &#39;8934&#39;, &#39;8856&#39;, &#39;8924&#39;, &#39;9050&#39;, &#39;8862&#39;, &#39;8863&#39;, &#39;8764&#39;, &#39;9047&#39;, &#39;9045&#39;, &#39;9055&#39;, &#39;8746&#39;, &#39;8814&#39;, &#39;8714&#39;, &#39;8760&#39;, &#39;8944&#39;, &#39;8958&#39;, &#39;8959&#39;, &#39;8722&#39;, &#39;8743&#39;, &#39;8785&#39;, &#39;8946&#39;, &#39;8860&#39;, &#39;8877&#39;, &#39;8715&#39;, &#39;9011&#39;, &#39;8945&#39;, &#39;9023&#39;, &#39;8947&#39;, &#39;9015&#39;, &#39;8777&#39;, &#39;8753&#39;, &#39;8797&#39;, &#39;8899&#39;, &#39;8734&#39;, &#39;8705&#39;, &#39;9042&#39;, &#39;8936&#39;, &#39;8787&#39;, &#39;8950&#39;, &#39;8888&#39;, &#39;8723&#39;, &#39;9018&#39;, &#39;9019&#39;, &#39;8948&#39;, &#39;8942&#39;, &#39;8890&#39;, &#39;8969&#39;, &#39;8906&#39;, &#39;8907&#39;, &#39;8960&#39;, &#39;9021&#39;, &#39;8713&#39;, &#39;9009&#39;, &#39;9014&#39;, &#39;9022&#39;, &#39;8831&#39;, &#39;8707&#39;, &#39;8724&#39;, &#39;9033&#39;, &#39;9024&#39;, &#39;9038&#39;, &#39;8829&#39;, &#39;9034&#39;, &#39;9027&#39;, &#39;9025&#39;, &#39;9031&#39;, &#39;9026&#39;, &#39;9029&#39;, &#39;9030&#39;, &#39;9032&#39;, &#39;9041&#39;, &#39;9039&#39;, &#39;9051&#39;, &#39;9028&#39;, &#39;8994&#39;, &#39;8765&#39;, &#39;8977&#39;, &#39;8808&#39;, &#39;8978&#39;, &#39;8809&#39;, &#39;8876&#39;, &#39;9008&#39;, &#39;8883&#39;, &#39;8768&#39;, &#39;8823&#39;, &#39;8740&#39;, &#39;8873&#39;, &#39;9013&#39;]

尝试访问 stat-1 中的第二个 span 子元素

response.css('div.caption span.stat-1 span:nth-child(2)::text').get()
英文:

Try to access second span child in stat-1

response.css(&#39;div.caption span.stat-1 span:nth-child(2)::text&#39;).get()
