The recommendation would almost certainly be to use the XML Parser Service. You can see it in the spec at https://osgi.org/specification/osgi.cmpn/7.0.0/util.xml.html <https://osgi.org/specification/osgi.cmpn/7.0.0/util.xml.html> - note that this spec is pretty old, so all the examples use the low-level OSGi framework API.
