Does anyone know of a parser for multi-section fixed-length files?

[cjard]

This is close:
http://www.codeproject.com/csharp/ReportParser.asp

But it doesnt cateer for files laid out like:

file header
  section 1 header
    detail line
    detail line
  section 1 footer
  section 2 header (same layout as 1)
    detail line (same layout as 1)
 ...
  section N header (same layout as 1)
    detail line (same layout as 1)
  section N footer (same layout as 1)
file footer

The files we get are blocks of detail organized into sections, each section header and footer and detail line obey the same pattern but they need distincting. The microsoft text driver cannot handle this..

Its looking like I'm going to be writing a forward-reading custom parser..
