Topic: Find all instances of a type

Hey, Is there any existing method for finding all elements of a type? In my case I have to find every ResourceReference in any given resource.

Yes, there is, but you will need to add the Hl7.Fhir.ElementModel package to convert your resource to a TypedElement. You can then select all elements of type reference and parse them into ResourceReference objects. Here's an example, with res being your given resource.

var refs = res.ToTypedElement().Descendants().Where(e => e.InstanceType == "Reference");

foreach (var r in refs)
{
    // use r.ParseResourceReference() to work with the ResourceReference
}

Thank you! This is just what I needed.
