file processing

HI All,
I required your suggestion here,
 have Transaction from pip to xml(IDOC) and csv .
pip as a source for both IDOC creation and CSV creation.
1st condition:I have to create idoc if ProductLineItem.GlobalPurchaseOrderStatusCode = ‘ACCEPT’
IF ‘PENDING’or ‘REJECT’ – i need to create CSV file

and if ‘ACCEPT’ i need to check one more condition as below

2nd condition:for every unique <ProductLineItem><DocumentLineReference><ProprietaryDocumentIdentifier> where <GlobalDocumentReferenceTypeCode = ‘Sales Order’> 
here is the part of schema structure through sample
<ProductLineItem>(unbounded)
<buyerLineItem>
  <LineNumber\>
  </buyerLineItem>
<comments>
  <FreeFormText></FreeFormText>
  </comments>
<DocumentLineReference>(unbounded)
  <DateTimeStamp></DateTimeStamp>
  <GlobalDocumentReferenceTypeCode></GlobalDocumentReferenceTypeCode>
  <ProprietaryDocumentIdentifier></ProprietaryDocumentIdentifier>
  </DocumentLineReference>
  <GlobalProductUnitOfMeasureCode></GlobalProductUnitOfMeasureCode>
  <GlobalPurchaseOrderStatusCode>Accept</GlobalPurchaseOrderStatusCode> (max occur :1)
<isDropShip>

One approach I followed would be to use the standard XML Debauching for each ProductlineItem
This in combination with a property schema where the GlobalPurchaseOrderStatusCode = “ACCEPT” would help you route between two send ports, first where the XML is mapped to a FF Schema for generating the CSV and the second where the XML is mapped to the IDOC schema and sent to SAP using the Adapter.

But here if I followed like above  i am missing second condition
Please anyone advice here
