I have a php script which parses xml file. I want to create plugin for Nagios, which will use that php script, or any other solution that would parse the xml file for attribute to change and monitor it via Nagios. Is it possible?

This is definitely possible, but it has a complication that you may not have addressed. In order to monitor for a change, you must have a way of recording the "previous" value outside of the PHP script in question - simply parsing the XML won't let you know if anything is changed, it will only let you compare against constant values.
Ultimately, the create a Nagios plugin, you need something that generates the appropriate return code and (optionally) outputs a single line with the Nagios status first. An example OK message would be:
OK - value unchanged
and an example warning message would be:
WARN - value unknown
and an example critical message would be:
CRIT - value changed to something bad
See https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/3/en/pluginapi.html for details of how to write a Nagios plugin - the language used is immaterial as long as the return code is correct.
