How to force field to appear in input structure in content conversion

Question

Hi all,
I am doing file content conversion in sender File adapter. Here is the structure
Header
Body
   field1 - length 2
   field2 - occurrence 1:1, length 3
   field3 - length 2
   field4  length 2
Trailer
Here is the fixed length file that is inputed into XI
<b>header22   2211trailer</b>
field2 occrence is 1:1 and as you se from the file example field2 from the body is empty(just space).But  When I do the content conversion I don;t have this field showing up in my structure!??!!
I want to make sure that field2 appears even as empty field because that is screwing my mapping!?
Can you please have any idea how to make sure that field is in my input structure when I pass spaces?Can I force it somehow?
Thanks all.

Hi Jon,
Yes you are right.
For Ex: ur XML is
<1>a</1>
<2>b</2>
and sometime is there is no value ur FCC will become
<1>a</1>
So what you have to do is in the message mapping take the source element
if <2> exists then <2>---->Target
else
<2>---->Constant(space)
and this "exists" is a standard function in NodeFunctions.
