How to iterate over one word in each line?

Question

Python

elif '<math-input-answer>' in answer_row['content']:
            correct= answer_row['content'].partition('<math-input-answer>')[2].partition('</math-input-answer>')[0]
            print(correct)

I use this code to get values ​​from this text that are inside the math-input-answer tag, but now it only gets the first x + y value, and does not go further, how to put it in a loop?

<p><vim-math id="m7859635math1">AB+CD=|</vim-math><math-input id="m7859635MI1" keyboard-skin="junior" keyboard-type="base" strict-check="false">
  <math-input-answer>x+y</math-input-answer>
  <math-input-answer>y+x</math-input-answer>
</math-input><vim-math id="m7859635math2">|+|</vim-math><math-input id="m7859635MI2" keyboard-skin="junior" keyboard-type="base" strict-check="false">
  <math-input-answer>t+z</math-input-answer>
  <math-input-answer>z+t</math-input-answer>

Answer 1

data = '''<p><vim-math id="m7859635math1">AB+CD=|</vim-math><math-input id="m7859635MI1" keyboard-skin="junior" keyboard-type="base" strict-check="false">
  <math-input-answer>x+y</math-input-answer>
  <math-input-answer>y+x</math-input-answer>
</math-input><vim-math id="m7859635math2">|+|</vim-math><math-input id="m7859635MI2" keyboard-skin="junior" keyboard-type="base" strict-check="false">
  <math-input-answer>t+z</math-input-answer>
  <math-input-answer>z+t</math-input-answer>'''
  
string = '<math-input-answer>'
results =[]
 
def get_text(line):
    line = line.split('>')[1]
    line = line.split('<')[0]
    return line
     
for line in data.splitlines():
    if string in line:
        result = get_text(line)
        results.append(result)
print(results)

Here I wrote a completely ugly parsing function, because I'm too lazy to screw bs4 or something like that, for example, stuck on the phone, or compose regex ...
instead of it, you can substitute a more different one at your discretion.
