Getting entire source structure via udf

Hi Experts,

Below is my source structure.

<record> 

<first> 

<second>

<third> 

<fourth>

.

.

.

.

<record>

It has around 100 fields. I want to write a udf by having these 100 fields as arguments (Also i don't want to give the filed names one by one in the arguments). Is there any other way to get all these values without adding all of them in the arguments?

Is it possible to get them via <record>?

Thanks in advance!

Regards,
