Library to read config files (xml or json) that detects file´s changes

I have a XML configuration file like this:

<configuration>
<items>
    <item key="KEY_NAME">
        3
    </item>
</items>
</configuration>

I need some library to read (only read) the files values but can detect changes (for example, change value 3 for 5) without restart application.

I was using njupiter for that, but this project was deprecated. I found MiniFSWatcher, do you known some other library?

Thanks,
