I am using the NuGet package Hl7.Fhir.STU3 to save me from having to create all the POCO classes.
The Json returned from the NHS FHIR Server is (I've removed a huge chunk to make it easier to read):
{
"id": "000049660991",
"meta": {
"versionId": "3",
"profile": [
"https://fhir.nhs.uk/STU3/StructureDefinition/eRS-ReferralRequest-1"
]
},
"resourceType": "ReferralRequest",
"supportingInfo": [],
"intent": "plan"
}
The problem comes when I try to deserialize it as the "supportingInfo" element contains an empty array so I receive the following error (ignore the position):
Hl7.Fhir.Serialization.DeserializationFailedException: 'One or more errors occurred. (An array needs to have at least one element. At line 1, position 2445.)'
Is there a way to ignore empty arrays?

I've got json file with some nested objects inside subs in it:
{
"version": 1,
"data": [{
"married": true,
"subs":[
{
"name":{
"sub1":{}
**},**
},
]
},
]}
If I add another 'name' object (with comma as separator), jsonDecode returns nothing.
if there goes single object, without comma - it's ok.
My Json structure is correct, and it's not restricted to use nested objects at all. Please anyone help.
This line has problem **},** and if changed to }, the problem will be solved..
you can check your json by online tools (e.g https://jsonformatter.curiousconcept.com/#)
Should be a no brainer, but I'm can't seem to access the elements returned from Newtonsoft's json deserializer.
Example json:
{
"ns0:Test": {
"xmlns:ns0": "http:/someurl",
"RecordCount": "6",
"Record": [{
"aaa": "1",
"bbb": "2",
},
{
"aaa": "1",
"bbb": "2",
}]
}
}
var result = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(somestring);
Stripping out the json up to the Record text, i can access the data without issue.
i.e. result.Recordcount
If i leave the json as shown above, can someone enlighten me how to access Recordcount?
All inputs appreciated. Thanks!
For those JSON properties that have punctuation characters or spaces (such that they cannot be made into valid C# property names), you can use square bracket syntax to access them.
Try this:
int count = result["ns0:Test"].RecordCount;
I have a large JSON file that looks similar to the code below. Is there anyway I can iterate through each object, look for the field "element_type" (it is not present in all objects in the file if that matters) and extract or write each object with the same element type to a file? For example each user would end up in a file called user.json and each book in a file called book.json?
I thought about using javascript but to my knowledge js can't write to files, I also tried to do it using linux command line tools by removing all new lines, then inserting a new line after each "}," and then iterating through each line to find the element type and write it to a file. This worked for most of the data; however, where there were objects like the "problem_type" below, it inserted a new line in the middle of the data due to the nested json in the "times" element. I've run out of ideas at this point.
{
"data": [
{
"element_type": "user",
"first": "John",
"last": "Doe"
},
{
"element_type": "user",
"first": "Lucy",
"last": "Ball"
},
{
"element_type": "book",
"name": "someBook",
"barcode": "111111"
},
{
"element_type": "book",
"name": "bookTwo",
"barcode": "111111"
},
{
"element_type": "problem_type",
"name": "problem object",
"times": "[{\"start\": \"1230\", \"end\": \"1345\", \"day\": \"T\"}, {\"start\": \"1230\", \"end\": \"1345\", \"day\": \"R\"}]"
}
]
}
I would recommend Java for this purpose. It sounds like you're running on Linux so it should be a good fit.
You'll have no problems writing to files. And you can use a library like this - http://json-lib.sourceforge.net/ - to gain access to things like JSONArray and JSONObject. Which you can easily use to iterate through the data in your JSON request, and check what's in "element_type" and write to a file accordingly.
I am new to using Mule and having a problem with outputting nested Json. I am using mule 3.3 and the GUI interface. I add the database component to my flow and run some simple SQL including a 'one to many' join. After this I added an 'Oject to Json' component, the problem is the resulting JSON is flat it does not nest the 'one to many' elements. For example I expect:
{
"firstName": "John",
"phoneNumber": [
{
"type": "home",
"number": "212 555-1234"
},
{
"type": "fax",
"number": "646 555-4567"
}
]
}
I actually get:
{
"firstName": "John",
"type": "home",
"number": "212 555-1234"
}
Can anyone give me any direction on what I am missing?
Since you haven't posted your configuration, it's hard to tell exactly what you're doing. Anyways...
The select query returns a flat view of the users data. If you want to create a structured representation of it, you'll have to create a transformer to do so, prior to serializing to JSON.
Alternatively, you can use an ORM to map your data to objects then serialize these objects to JSON.
How to read the following json file and display in extjs grid columns?
{
"users": [
{
"id": 123,
"name": "Ed",
"orders": [
{
"id": 50,
"total": 100,
}
]
}
]
}
Could someone explain how to read the nested data in the json? I have tried a lot of options like renderer functions, using the '.' property, etc.
Edit: I would like to read the data within "orders", which are "id" and "total".
You are trying to read in an array nested in an object nested in an array.
So your root would have to be users[0].orders
Is that really what you are trying to do?
Working code:

Why is your code nested like this?
