Open Live Script

This example shows how to assign a script as the PreImportFcn callback for an Import node. You get the contents of the PreImportFcn callback for an Import node and register a different script as the PreImportFcn callback after you import the requirements.

Import the Requirements

Use slreq.import to import the ReqIF™ file mySpec.reqif into Requirements Toolbox™. Name the imported requirement set myReqSet and register the script myPreImportScript as the PreImportFcn callback to use during import. Return a handle to the requirement set.

[~,~,rs] = slreq.import("mySpec.reqif", ...
    ReqSet="myReqSet",preImportFcn="myPreImportScript");

The script myPreImportScript uses slreq.getCurrentImportOptions to get the import options, then specifies the attribute mapping file to use during import.

type myPreImportScript.m
importOptions = slreq.getCurrentImportOptions;
importOptions.MappingFile = "myMappingFile.xml";

The mapping file myMappingFile.xml uses a generic mapping.

Get the custom ID for the requirement with Index set to 1.

req1 = find(rs,Index="1");
cID = req1.CustomId
cID =

  0×0 empty char array

The generic mapping does not map the ReqIF attribute ID to the Requirement Toolbox attribute Custom ID. Instead, ID imports as a custom attribute. Get the value for the ID custom attribute for Requirement 1.

cID = getAttribute(req1,"ID")
cID = 
'A1'

Get and Set the PreImportFcn Callback Script

Get a handle to the Import node, then register the script myPreImportScrip2 as the PreImportFcn callback. Confirm that the registered callback was changed.

topRef = children(rs);
setPreImportFcn(topRef,"myPreImportScript2")
newCallback = getPreImportFcn(topRef)
newCallback = 
'myPreImportScript2'

The script myPreImportScript2 uses slreq.getCurrentImportOptions to get the import options, then specifies the attribute mapping file to use during import.

type myPreImportScript2.m
importOptions = slreq.getCurrentImportOptions;
importOptions.MappingFile = "myMappingFile2.xml";

The mapping file myMappingFile2.xml maps these attributes from the ReqIF™ file to these properties in Requirements Toolbox™:

  • ReqSum to Summary

  • Desc to Description

  • ID to Custom ID

Update the requirement set. The PreImportFcn callback script also executes when you update the requirement set.

updateReferences(rs,topRef);

Get the custom ID for the requirement with Index set to 1.

req1 = find(rs,Index="1");
cID = req1.CustomId
cID = 
'A1'
