Request you to guide me, Is it possible to convert hex value to ascii format using dfdl. I am working on financial transaction message and facing DFDL parsing issue, value is not getting properly parsed. Is there any specific code page which can be used to encode the value into required format. Kindly suggest.
Please find below sample message:
Hex Input : 353232323233323237343339 Required ASCII/String Output : 522223227439
Not sure about the name of the format.[/b] |

Hex representation is not actually a code page.
It is a printable way of representing the binary value of one byte as two hex digits.
If you treat printable hex as data, it won't work very well. If the input really is printable hex data, then you need to convert each two character hex digit back into a single byte of actual data.
ESQL has the CAST function which can help with this. If DFDL can do it then I am sure Tim will know how.

I know it will work with below mentioned statement , but I want to avoid ESQL coding .
And want to know if its possible to get the required output using DFDL ?? |

I believe there is a DFDL schema on GitHub for this variant of ISO8583. When I solved it, I used ESQL to convert the bitmaps into the format required by the standard DFDL schema. |
