Loop through all the fields in the form (main form, sub form, sub sub form, table, sub table)

[Techi_Panda]

Hi Experts

I want to check all the field name which contains text "_lock" in all the field names. The for hierarchy  is

form1>page1>

                    Subform>Table>row>cell>Textfield_lock

                    Subform>Subform>Table>row>cell>Textfield_lock

                   Table>row>cell>Textfield_lock

I have tried with previous posts related to this only i am able to count the root elemets not the sub elements

Can anyone suggest me how can I loop through all the fields includes the sub forms?

Thanks in advance
