PI mapping complex structure file to Idoc

I have a problem with a mapping complex structure file to Idoc

My inbound file is structured like that :

<Z1CONF03>

data

</Z1CONF03>

<Z1CONF04>

data

</Z1CONF04>

<Z1CONF03>

data

</Z1CONF03>

<Z1CONF04>

data

</Z1CONF04>

And I want to put in a Idoc structured like that :

Idoc :

Segment Z1CONF03

     Segment Z1CONF04

Segment Z1CONF03

     Segment Z1CONF04

But my result is like that :

Segment Z1CONF03

     Segment Z1CONF04

     Segment Z1CONF04

Segment Z1CONF03

As you can see below :

How could I do ?

Thanks for your answers.
