I have tried to parse the output of this call:

https://fhir.loinc.org/CodeSystem/$lookup?system=http://loinc.org&code=28890-2

and I don't know what's the right class to use.

I need to extract:

* different components of the LOINC code

* Component

* FSN

* LCN

Is there a nice class that I can use to extract the different components?
