How to remove XML Container Element if its fields are empty ?

Hi Team,

I have a requirement where in my xml is as below

<SiebelMessage>

<IO>

<IC1>

  <Field1> 1</Field1>

  <Field2> 2</Field3>

  <Field3> 3</Field3>

</IC1>

<IC2>

  <Field1> 1</Field1>

  <Field2> 2</Field3>

  <Field3> 3</Field3>

</IC2>

<IC3>  //---- Since the fields are empty

  </IC3>

</IO>

<SiebelMessage>

I would like to only see as below

<SiebelMessage>

<IO>

<IC1>

  <Field1> 1</Field1>

  <Field2> 2</Field3>

  <Field3> 3</Field3>

</IC1>

<IC2>

  <Field1> 1</Field1>

  <Field2> 2</Field3>

  <Field3> 3</Field3>

</IC2>

</IO>

<SiebelMessage>

IC 3 must be removed from the message since its fields are null/empty , I dont want to write custom code because its not limited to IC3 i might have very well 20 ICs and randomly only couple of IC will have data, so need some configurable solution ? Any ideas please
