Hi,

I am developing a code to create an XML file from the data retrieved from an excel sheet. The retrieved data are stored in a class object(objClsScene for example which is an object of clsScene). clsScene has properties like description (string), name (string) , rate (integer) etc. It also has objects of other classes as its properties ( for example: objCls1, objCls2, objCls3 etc).

Is there any way by which i can iterate or loop through the properties of objClsScene so that i may extract the data stored in objCls1, objCls2 etc depending on my requirements. Or are there any other method by which i may attain the same result?

I am new to matlab coding and any thoughts on this would be really appreciated.

Thanks in advance.

在 MATLAB Online 中打开

props = properties(objClsScene);
for iprop = 1:length(props)
  thisprop = props{iprop};
  %%%Add logic here if you want to work with select properties
  thisprop_value = objClsScene.(thisprop);
  %%%Add logic here if you want to do something based on the property's value
end
