JSON parser
#1
Hi Gintaras,
Would it be hard to incorporate a JSON parser similar to the IXml and IXmlNode interfaces already in QM?
There is something from MS called System.Runtime.Serialization.Json
https://msdn.microsoft.com/en-us/library...10%29.aspx

Is there a .NET limitation of QM for this?

Thanks,
Stuart

Function JsonToXml
Code:

function'IXml $JSON [flags] ;;flags: 1 display XML text in QM output

;Converts JSON text to XML and returns IXml object.

;IXmlNode r=x.RootElement
;;get simple
;out r.Child("hello").Value
;;get with XPath
;out r.Path("Address/State").Value
;;get array
;ARRAY(IXmlNode) a; r.Path("a/*" a)

Maybe not all code was copied. This error would be if the code does not have the #ret line.
