Nemsis provides the entire schema in XSL files which are used to validate your PCR data for structural correctness.
Normally you are going to use XML validation for this process, but what if you had the schema as C sharp objects in your source code?
Microsoft has a utility which allows automatic conversion of XSL files to C sharp source code. We will describe the process of using this utility against the Nemsis schema.
The Microsoft Windows SDK contains a utility called XSD.exe. The Microsoft Windows SDK will be installed during the Visual Studio installation process.
The path C:\Program Files (x86)\Microsoft SDKs\Windows contains the versions of the SDKs you have installed.
I will be using the latest version of the utility located at: C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.2 Tools\XSD.exe
Open a command prompt:
Run this command to change your directory: CD C:\Temp\NEMSIS_XSDs
Run this command to create your c sharp file:
"C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.2 Tools\xsd.exe" /classes /language:CS EMSDataSet_v3.xsd
This will create a file C:\Temp\NEMSIS_XSDs\EMSDataSet_v3.cs
Visual Studio Example
I have created an example project with the EMSDataSet_v2.cs file. Download it from my GitHub repository.
With the new class you can create objects which conform to the Nemsis spec. Here is an example of a Patient object. The field names can be referenced from the Nemsis website: http://nemsis.org/media/nemsis_v3/release-3.4.0/DataDictionary/PDFHTML/DEMEMS/index.html
Once the new Patient object is defined we can use it like so:
We now have a Nemsis 3.4 compatible C Sharp object group to create many electronic patient software products!
