File Adapter with Conversion - XML with Hierarchy?

Question

XI 3.0 (SP9)
We are using the inbound file adapter with conversion to convert a flat file that has header and line items.  I would have thought that the data type should have been setup something like this:
<data type>
<header>
  <item>1</item>
  <item>2</item>
</header>
</data type>
Our flat file looks like this:
H12345
I12345
We have only been able to configure the file adapter to bring in the data like this:
<data type>
<header></header>
<item>1</item>
<item>2</item>
</data type>
What is the proper way to inbound data through a file adapter that has structure conversion like this?
Do all of the elements get put under the root node, or is there a way to build structure?
Do we need to build the data type to correspond with the exact way that the data will come in from the file adapter?
Thanks

Not quite sure what you want to get, as the flatfile and xml structure does not contain the same values.
However, I will try to give you an example:
Your flat file looks like this:
H12345
I12345
If the first row is header and the next is a line, then you need to specify the fila adapter with the following:
Document name = datatype
Recordset name = recordset
Recordset structure = header,1,item,*
Recordsets per message = *
Recordset sequence = Ascending (need SP10 for this, but you do not need it for this)
Keyfieldname = id
header.fieldFixedLengths = 1,5
header.fieldNames = id,number
header.keyFieldValue = H
header.lastFieldsOptional = Yes
item.fieldFixedLengths = 1,5
item.fieldNames = id,number
item.keyFieldValue = H
item.lastFieldsOptional = Yes
This will create something like this:
<datatype>
<recordset>
<header>
<id>H</id>
<number>12345</number>
</header>
<item>
<id>I</id>
<number>12345</number>
</item>
</recordset>
</datatype>
Hoever, if both rows are "item" rows , then you need to specify the file adapter with the following:
Document name = datatype
Recordset name = header
Recordset structure = item,*
Recordsets per message = *
Recordset sequence = Ascending (need SP10 for this, but you do not need it for this)
item.fieldFixedLengths = 1,5
item.fieldNames = id,number
item.lastFieldsOptional = Yes
This will create something like this:
<datatype>
<header>
<item>
<id>H</id>
<number>12345</number>
</item>
<item>
<id>I</id>
<number>12345</number>
</item>
</header>
</datatype>
Q: Do we need to build the data type to correspond with the exact way that the data will come in from the file adapter?
A: Yes!
Good luck!
