Answer 1

Your lines include the line separator, \n. You can strip the line with str.rstrip():

with open(file) as openfile:
    for line in openfile:
        if "[testclass]" in line:
            etree.SubElement(subroot, "tagxyz").text = line.rstrip('\n')

In future, use the repr() function to debug such issues; you'll readily see the newline represented by its Python escape sequence:

>>> line = '[testclass] unique_value_horse\n'
>>> print(line)
[testclass] unique_value_horse

>>> print(repr(line))
'[testclass] unique_value_horse\n'
>>> print(repr(line.rstrip('\n')))
'[testclass] unique_value_horse'
