使用 Python 在包含给定单词的标签之间提取文本

Question

我有一些来自 XML 文档的文本，我试图在其中提取包含某些单词的标签中的文本。

例如下面：

search('adverse')

应该返回包含单词“adverse”的所有标签的文本

Out: 

  [

    "<item>The most common adverse reactions reported in subjects receiving coadministered dutasteride and tamsulosin were impotence, decreased libido, breast disorders (including breast enlargement and tenderness), ejaculation disorders, and dizziness.</item>"

  ]

和 search('clinical')

应该返回两个结果，因为两个标签包含这些词。

Out: 

  [

    "<title>6.1 Clinical Trials Experience</title>", 

    "<paragraph id="ID41">The clinical efficacy and safety of coadministered dutasteride and tamsulosin, which are individual components of dutasteride and tamsulosin hydrochloride capsules, have been evaluated in a multicenter, randomized, double-blind, parallel group trial (the Combination with Alpha-Blocker Therapy, or CombAT, trial) </paragraph>"

  ]

为此我应该使用哪些工具？正则表达式？BS4？任何建议都非常感谢。
