Parsing Log records with regular expressions

From: "Kris K." <iamkrisko@...>
Date: 2011-02-03 21:38:24 UTC
List: ruby-talk #378061
I have a log file which is text based which has records in two formats
of the following form
`
A|B|C|D\n
A|B|C|D|E\n
\n
Exception\n
\n
\tstack trace line1\n
\tstack trace line2\n
\tstack trace line3\n
\n
A|B|C|D\n`

The first form (A|B|C|D) has statically defined columns delimited by a
pipe symbol. The second form has the last character "E" which implies an
exception record. If it is an exception record the information about the
exception follows. The exception information starts with a line
"Exception", followed by another newline and stacktrace on multiple
lines. Each stacktrace element starts with a tab.

I am parsing this file with ruby. Currently I am reading line by line
and building the log records. This is working fine.

I am wondering if I could rely on regular expressions to do it instead
of reading line by line - I could read a chunk of the file and apply two
regular expressions to see if there is a match and if I find the match
process the record and move to the next record. If there is no match,
then I combine multiple chunks until I find a match. Is this approach a
valid
consideration? Is this doable with Ruby? If there are any open source
projects, that do something like this, can someone point me to it? Also
any thoughts which one is more efficient and why? Appreciate any
feedback.
