Transforming XML File to Flat File Format - xslt

Question

I'm looking for the other references regarding the transformation of XML file to Flat File format and I have seen many of them. I've tried some of the codes that I saw over the internet and it helps a lot. I tried to do my own XSLT file and I can't get what I want in my output. Also, I need to minimize my coding in the XSLT since I have a lot of coding and condition to applied from Header Record, Detail/Contra Record and Trailer. The value of the header record is correct, however, 2nd and 3rd row of the current output is incorrect. I need to populate for every Transaction there should have 1 detail and 1 Contra. The output should look like what's on the expected output.
Thank you.

Explanation: The value AAAAAA comes from the Payment/Transaction/CreditorParty/FinancialAccount/ID and should only have 6 characters. The BOA-t-12 comes from the Payment/Transaction/TransactionID and this field should only have 8characters. 0 is the hardcoded value, as well as, the value 99. On the next line, the 11111M comes from the Payment/DebtorParty/FinancialAccount/ID, Payment1 is from the Payment/DisplayID and 0 and 17 are the hardcoded value. From the next line and soon, it will only repeat the process and this time the value will be get from the next occurrence of Payment/Transaction.
For every occurrence of Payment/Transaction, it will create 1 Detail record and 1 Contra record. In my example, I have 4 Transaction, and the output should have:
Detail - 1st occurrence of Transaction
Contra - 1st occurrence of Transaction
Detail - 2nd occurrence
Contra - 2nd occurrence
Detail - 3rd occurrence
Contra - 3rd occurrence
Detail - 4th occurrence
Contra - 4th occurrence
This is a fixed-length format.

Answer 1

Try this as your starting point:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xpath-default-namespace="http://schema.infor.com/InforOAGIS/2">
<xsl:output method="text" encoding="UTF-8"/>
<xsl:template match="/SyncCreditTransfer">
<!-- Start of Header Record -->
<!-- skipped for the purpose of this example -->
<!-- End of Header Record -->
<!-- Records -->
<xsl:for-each select="Data/Record/Payment/Transaction">
<!-- Start of Detail Record -->
<xsl:value-of select="substring(CreditorParty/FinancialAccount/ID, 1 , 6)"/>
<xsl:value-of select="substring(TransactionID, 1 , 8)"/>
<xsl:text>099
</xsl:text>
<!-- End of Detail Record -->
<!-- Start of Contra Record -->
<xsl:value-of select="../DebtorParty/FinancialAccount/ID"/>
<xsl:value-of select="../DisplayID"/>
<xsl:text>017
</xsl:text>
<!-- End of Contra Record -->
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
This still needs more work on the "contra" record, but you have not explained that part.
Note:
the use of xpath-default-namespace to handle the namespace used by your input;
the use of xsl:for-each to create a record for each transaction;
Note also that when the output method is text, using xsl:element makes no sense.
