[antlr-interest] Parsing a Fixed length file

[Manikandan Subramanian]

Hi,

This is one part of the bigger problem and just the startup. I need ANTLR
for sure, because I need to do data translation from one format to other
format. Source data structure could be fixed length data / delimited / some
cryptic data and Target data structure is XML.

As Gavin suggested, I think I may be need to some pre-processing to clean
the data and then give the cleaned data to ANTLR. But I am just wondering
whether is it good such things ANTLR itself instead of writing a framework
from the scratch.

Regards
Mani
