Hi!

Maybe you could use something like:

import re

string1 = '''<?xml version="1.0" encoding="utf-8"?>
<metafile version="3.6" client="site">
<name>English (en-GB)</name>
<version>3.6.0</version>
<creationDate>July 2016</creationDate>
<author>Joomla! Project</author>
[ ... ]'''
requirement1 = re.search('<version>(.*)</version>', string1)
print(requirement1.group(1))

that produces the following output:

Output:
3.6.0

All the best,

You're welcome! Smile

why not parse html/xml with regex is discussed so many times... use proper tools for the task or it will bite you when you don't expect

Hi again!

Although I always try to address a problem from the point of view and knowledge of a newbie like myself, if anyone from this site advises not to use what I have suggested in good faith, I would take their advice into consideration, as their knowledge is much much deeper than mine.

All the best,
