Mapping

Hi everyone,

I have a following scenario..

Source Message

<Maintag>

<tag1>

<number>1</number>

<message>This is</message>

<Date>03/27/2006</Date>

</tag1>

<tag2>

<num>1</num>

<mes>crazy</mes>

<Time>11:30</Time>

</Maintag>

Target Message

<Result>

<number>1</number>

<message> This is crazy</message>

<Date>03/27/2006</Date>

<Time>11:30</Time>

</Result>

How can I do this mapping? Can I do it in GUI or need Java mapping??

Thanks for the suggestions...
