Mapping Problem in IDOC to XML scenario

Question

hi,
In the target i have a tag which says:
Extrinsic 0..unbounded
name     required
I have to map the above target to a source which comes from different IDOC segments.
E.g.
if E1EDP17.Qualf = '002' then map the E1EDP17.lktext to the "name"
if E1EDP17.Qualf = '001' then map the E1EDP17.lktext to the Extrinisc.
If data resides in other segments, how would i map those segments to the same output in xml.
Example:
<Extrinsic name="a">test</Extrinsic> -> this comes from E1EDP17 segment
<Extrinsic name="a">test</Extrinsic> -> comes from segment A
<Extrinsic name="a">test</Extrinsic> -> comes from segment B
How can i use a single Target to map from different sources if they are in different segments?
Any tips?
Thanks,
KP

Tirumal,
U will have to use comination of node functions like <b>exists</b> and <b>mapWithDefault</b>.
Are you sure that, E1EDP17.Qualf will have the value '002' or '001'.
There are some very good blogs on mapping by Sravya. Go through them and also go through the following link.
