Parsing XML inner messages list using Python

I am trying to parse the following messages and store them in a list using python. How can I store the messages in a list?

I reached the id and the language by the following code, but I need to find the messages.

import xml.etree.ElementTree as ET

tree = ET.parse(filename)
root = tree.getiterator()
print (root[0].attrib)

<?xml version="1.0" encoding="UTF-8" standalone="no"?><author id="1aa8c430-853b-4bbc-b784-df4c88264ccd" lang="en">

Answer

Try:

import xml.etree.ElementTree as ET

tree = ET.parse("your_file.xml")
out = [d.text for d in tree.iter("document")]
print(out)

Prints:

[
    "@username bahaha! unfortunately i'm not a tshirt person      ",
    "Mercy reunion at Olive Garden #traditions :)     ",
    'After 3 months of beating my head against a wall over this persuasion, I've finally had my "aha!" moment!! #progress! #improvement!      ',
]
