FhirJsonParser Removing Leading Spaces

[MLuebbers]

I have a FHIR JSON string I wish to deserialize to a Resource object. There is an identifier in the resource that has a leading space and must remain that way but when inspecting the resulting Resource POCO from the parser that space is gone. I was under the impression the parser should leave JSON string fields exactly as they are without removing any leading or trailing whitespace. The SerializationSettings by default seem to remove the whitespace but I couldn't find an equivalent for the ParserSettings. I couldn't find any documentation about this behaviour, is this intended?

Hi @MLuebbers, we apply the same rules as for XML here: "Implementers SHOULD trim leading and trailing whitespace before writing and SHOULD trim leading and trailing whitespace when reading attribute values (for XML schema conformance)" (see https://build.fhir.org/xml.html). There is no setting for this as it confuses all kinds of tooling.

I created PR #3273 with a new serializer setting if that helps.

Thank you for the contribution, that indeed does make it a bit quicker 🙂

The latest snapshot with both changes is working for us. Thanks for all the help and the quick turnaround!

@andrzejskowronski @alexzautke. Is there a timeline for these changes to be released in 5.12.3?

We'll try to put out a new release in the next two weeks.
