Flat File to XML mapping Problem

I am facing some issues in mapping from flat file to XML. I have not reached to the stage of actually executing the scenario and the problem has not advanced beyond mapping tests.

Following are structures of inbound flat file (as specified in content conversion parameters of sender adapter)

Document Name  MMADealerStatementInbound_MT

Recordset Name  MMADealerStmtInbound_Type

Recordset Structure 

BatchHeader,1,DealerHeader1,,DealerHeader2,,DealerDetail,,DealerAgeing,,Trailer,1

Recordset Sequence  Ascending

Key Field Name  RecordType

Key Field Type  String (Case Sensitive)

Following are structures of Outbound XML file needed

All DealerDetail nodes are lumped together in first DealerStmt nodes. They need to be distributed across many DealerStmt nodes.

Company CompanyName 25

Company CompanyAddress StreetAddress Company Street Address 50

Company CompanyAddress City Company City 40

Company CompanyAddress State Company State 3

Company CompanyAddress ZIP Company ZIP 10

Company CompanyAddress Country Company Country 3

DealerStmt 0-unbounded DealerAgeing BalOver123 Over 123 days Old 15

Trailer DealersCount 5

Trailer TransCount 10

Trailer TotalAmount 20

Here is the mapping I used for this node.

/ns0:MMADealerStatementOutbound_MT/MMADealerStmtOutbound_Type/DealerStmt/DealerDetail=ifWithoutElse(stringEquals(/ns0:MMADealerStatementInbound_MT/MMADealerStmtInbound_Type/DealerDetail/RecordType=, const()), SplitByValue(/ns0:MMADealerStatementInbound_MT/MMADealerStmtInbound_Type/DealerDetail=))

My email address is hemnanirajesh@yahoo.com and i can send some screen shots to understand better.

I need help of XI mapping Gurus.

Thanks
