System is getting test steps in haphazard order

Hi,

Here I am trying to fetch test test steps associated with a test case and then print them all in Excel sheet. Now the problem is , in excel sheet the order of test steps doesn't match with the order in UI. I have checked using SOAP UI also. The ordering of test steps associated with a test case in XML are correct but when I am calling testCase.getTestSteps() method then system is fetching the test steps in no particular order. Do you have idea why the system is behaving like this or please correct me if I am doing something wrong.

Thanks,

Abhijit
