Extract text between tags containing a given word using Python

I have some text from an XML document where I am trying to extract the text within tags contain certain words.

For example below:

search('adverse')

should return the text of all the tags containing the word 'adverse'

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>"
  ]

and search('clinical')

should return two results since two tags contain those words.

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>"
  ]

What tools should I use for this? RegEx? BS4? Any suggestions are greatly appreciated.

Example Text:

 </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>

You could either hardcode it with a regex, or parse your xml file with a library like lxml

With a regex that would be:

import re

your_text = "(...)"

def search(instr):
    return re.findall(r"<.+>.*{}.*<.+>".format(instr), your_text, re.MULTILINE)

print(search("safety"))
