Parsing config file

Hi All,

I have a requirement to parse a file.

Let me clear you all on the req.

I have a job which contains multiple tasks and each task will have multiple attributes that will be in the below format. Each task will have some sequence number according to that sequence number tasks shld execute.

Code:
S.No. SeqNo# TaskID |Task Name | Attribute Name| Attribute Value1 1 1 | Java | classpath | sample.jar2 1 1 | Java | Runtime | -Xms -5123 2 2 | StoredPro | DB | sample.ini4 2 2 | StoredPro | ProcName | get_emp()
Like in the above format the infomation is written into the file.

The above job has 2 tasks (java, storedPro) with multiple attributes to each job. For example Java:- classpath, Runtime

I want to parse the file and and pick up the task and its attributes and execute as per the sequence number like java has to execute first with all attributes and stored proc fallows.

Please advice how can i achieve this.

Appriciate if any links or sample code.

Gearman::Task(3pm) User Contributed Perl Documentation Gearman::Task(3pm) NAME
Gearman::Task - a task in Gearman, from the point of view of a client SYNOPSIS
my $task = Gearman::Task->new("add", "1+2", { ..... }; $taskset->add_task($task); $client->do_task($task); $client->dispatch_background($task); DESCRIPTION
Gearman::Task is a Gearman::Client's representation of a task to be done. USAGE
Gearman::Task->new($func, $arg, \%options) Creates a new Gearman::Task object, and returns the object. $func is the function name to be run. (that you have a worker registered to process) $arg is an opaque scalar or scalarref representing the argument(s) to pass to the distributed function. If you want to pass multiple arguments, you must encode them somehow into this one. That's up to you and your worker. %options can contain: o uniq A key which indicates to the server that other tasks with the same function name and key will be merged into one. That is, the task will be run just once, but all the listeners waiting on that job will get the response multiplexed back to them. Uniq may also contain the magic value "-" (a single hyphen) which means the uniq key is the contents of the args. o on_complete A subroutine reference to be invoked when the task is completed. The subroutine will be passed a reference to the return value from the worker process. o on_fail A subroutine reference to be invoked when the task fails (or fails for the last time, if retries were specified). No arguments are passed to this callback. This callback won't be called after a failure if more retries are still possible. o on_retry A subroutine reference to be invoked when the task fails, but is about to be retried. Is passed one argument, what retry attempt number this is. (starts with 1) o on_status A subroutine reference to be invoked if the task emits status updates. Arguments passed to the subref are ($numerator, $denominator), where those are left up to the client and job to determine. o retry_count Number of times job will be retried if there are failures. Defaults to 0. o high_priority Boolean, whether this job should take priority over other jobs already enqueued. o timeout Automatically fail, calling your on_fail callback, after this many seconds have elapsed without an on_fail or on_complete being called. Defaults to 0, which means never. Bypasses any retry_count remaining. o try_timeout Automatically fail, calling your on_retry callback (or on_fail if out of retries), after this many seconds have elapsed. Defaults to 0, which means never. $task->is_finished Returns bool: whether or not task is totally done (on_failure or on_complete callback has been called) perl v5.10.1 2009-10-05 Gearman::Task(3pm)
