Using variable in file path in Python

Question

I've found similar questions to this but can't find an exact answer and I'm having real difficulty getting this to work, so any help would be hugely appreciated.

I need to find a XML file in a folder structure that changes every time I run some automated tests.

This piece of code finds the file absolutely fine:

import xml.etree.ElementTree as ET
import glob

report = glob.glob('./Reports/Firefox/**/*.xml', recursive=True)
print(report)

I get a path returned. I then want to use that path, in the variable "report" and look for text within the XML file.

The following code finds the text fine IF the python file is in the same directory as the XML file. However, I need the python file to reside in the parent file and pass the "report" variable into the first line of code below.

tree = ET.parse("JUnit_Report.xml")
root = tree.getroot()

for testcase in root.iter('testcase'):
    testname = testcase.get('name')
    teststatus = testcase.get('status')
    print(testname, teststatus)

I'm a real beginner at Python, is this even possible?

By "I need the python file to reside in the parent file and pass the report variable", do you mean that you need the Python file to reside in the parent directory, and pass the location of the report file to the tree variable? — Random Davis

using regex can get a pattern matching text If you need to get an element and its attribute. refer element using lxml — Devendran Nehru

Yes @Random Davis, sorry, I should have been clearer on that — S. Bunyard

Build the absolute path to your report file:

report = glob.glob('./Reports/Firefox/**/*.xml', recursive=True)
abs_path_to_report = os.path.abspath(report)

Pass that variable to whatever you want:

tree = ET.parse(abs_path_to_report )
