Using XML...

patient = FHIR.from_contents(xml)
puts patient.to_xmlUsing JSON...
json = File.read('patient-example.json')
patient = FHIR.from_contents(json)
puts patient.to_jsonCreating an Observation by hand...
obs = FHIR::Observation.new(
'status' => 'final',
'code' => {
'coding' => [{ 'system' => 'http://loinc.org', 'code' => '3141-9', 'display' => 'Weight Measured' }],
'text' => 'Weight Measured'
},
'category' => {

'value' => 185,
'unit' => 'lbs',
'code' => '[lb_av]',
'system' => 'http://unitsofmeasure.org'
)Using built in validation...
patient.valid? # returns true or false
patient.validate # returns Hash of errors, empty if validUsing a profile or structure definition...
sd = FHIR::Definitions.resource_definition('Patient')
sd.validates_resource?(patient) # passing in FHIR::Patient
# Validation failed? Get the errors and warnings...
puts sd.errors
