Thanks for the responses. I apologize if I didn't put my question correctly. If I need to export class from the intersystems development server the below methods will work. I do not want to export directly from the server. Let us consider the following scenario.

I am using SVN for my source control management.

I am working on 2 requirement and needs to edit Transform.cls

First I make some changes on Transform.cls and check into SVN with version 100

I continue to work on the same class and check into SVN with version 101

Now I want to deploy my code for requirement 1 which is version 100.

If I export from my Dev version then it will bring only the latest change which I do not want.

I created a script to pull the version 100 using the tag I created. 

Now I have the locally saved the Transform.cls file and create the XML file.
