Clearing all attributes of a Node

Hi Leads,

I have a screen which have 20 input fields.All fields are under a single node. I have one button as "CLEAR".

If I say clear, I need to clear all the Fields in the Screen.

Can you please help me, how can I do this?

I tried with SET_ATTRIBUTE_NULL, but need to call this method for all input fields.

Is there any other way to clear all the attributes of Node at a time?

Thanks,

Sandeep.
