Answer 1

您可以使用lxml.html解决方案：

from lxml import html

source = """

<div class="xyOfqd">

<div class="aAAD">

   <div class="Bgbcca">Updated</div>

   ...

   <span class="hthtb">

      <div><span class="hthtb">Text12</span></div>

   </span>

</div>"""

tree = html.fromstring(source)

print(tree.xpath('//div[.="MyText"]/following-sibling::span/div/span/text()'))
