FHIR XML to/from JSON converter library in Lua.
Online version available at https://fhir-formats.github.io.
To install FHIR-Formats, run:
$ luarocks install fhirformats
local to_json = require("fhirformats").to_json
local to_xml = require("fhirformats").to_xml
-- convert given XML content as a string to JSON
to_json("xml content")
-- convert an XML file given as a location to JSON
to_json("/path/to/file", {file = true})
-- convert XML content as a string to JSON and prettyprint it
to_json("xml content", {pretty = true})
-- convert an XML file given as a location to JSON and prettyprint it
to_json("/path/to/file", {file = true, pretty = true})
-- convert given JSON content as a string to XML
to_xml("json content")
-- convert an JSON file given as a location to XML
to_xml("/path/to/file", {file = true})
-- get the FHIR definition of an element
get_fhir_definition('Patient', 'animal', 'species')
-- returns a table with metadata about the element. Do not modify this table. Keys are:
-- _min (int): minimum cardinality
-- _max (string): maximum cardinality, either a number or *
-- _type_json (string): JSON rendering type. Possible values are: number, string, boolean
-- _weight (string): arbitrary number assigned to an element - higher the number, the lower in the XML structure it is
-- _kind (string): FHIR element kind. Possible values are: complex-type, resource, primitive-type
-- _type (string): FHIR element type. Possible values are: Address, Age, Annotation, Attachment, BackboneElement, CodeableConcept, Coding, ContactDetail, ContactPoint, Contributor, Count, DataRequirement, Distance, DomainResource, Duration, Element, ElementDefinition, Extension, HumanName, Identifier, Meta, Money, Narrative, ParameterDefinition, Period, Quantity, Range, Ratio, Reference, RelatedResource, Resource, SampledData, Signature, Timing, TriggerDefinition, UsageContext, base64Binary, boolean, code, date, dateTime, decimal, id, instant, integer, markdown, oid, positiveInt, string, time, unsignedInt, uri, xhtml
-- [1]: if present, this is a link to the base type of the resource
-- _derivations: if present, this is a map of resources that extend on this resource
