Hi there, Try to achieve: Compare individual attributes value within

Hi there,
Try to achieve:
Compare individual attributes value within same element between two CDT instances. For example, CDT[1].field1=CDT[2].field1 AND CDT[1].field2=CDT[2].field2 AND CDT[1].field3=CDT[1].field3 AND ...
Method has been Tried:
Use tostring to convert CDT into mutiple values text PV array via striping off "[,]" and splitting with ",". It returns as an array of {field1=value1,field2=value2,field3=value3....}. Use text set function to find out the diffence array of two CDT instances.
Problem:
It will break into unexpected extra CDT elements when there is/are one or more "," (comma) characters within CDT element values.
Appian Version: 7.6;
Help please:
Are there any other ways to achieve this?

Many thanks/Henry...
