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。示例文本： </highlight> </excerpt> <component> <section id="ID40"> <id root="fbc21d1a-2fb2-47b1-ac53-f84ed1428bb4"></id> <title>6.1 Clinical Trials Experience</title> <text> <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> <list id="ID42" listtype="unordered" stylecode="Disc"> <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>
