我希望它得到html列表，但结果是[]，请帮助我，请使用xpath而不是其他方法。谢谢 我已经解决了这个问题，只需使用以下代码，在我的代码中添加//*即可：
buy_info2 = tree.xpath('//div[contains(@title, "item-body")]//*')
谢谢 我已经解决了这个问题，只需使用以下代码，在我的代码中添加//*即可：
buy_info2 = tree.xpath('//div[contains(@title, "item-body")]//*')
谢谢 您可以使用类名拉取div：
In [2]: from lxml import html
In [3]: xml = html.fromstring(h)
In [4]: div = xml.xpath("//div[@class='item-body']")[0]
In [5]: print(html.tostring(div))
<div class="item-body" title="item1">
<div title="buyer-name">Carson Busses</div>
<span class="item-price">$29.95</span><br>
</div>
：从lxml导入html
在[3]中：xml=html.fromstring（h）
[4]中的div=xml.xpath（“//div[@class='item-body']]”[0]
在[5]中：打印（html.tostring（div））
