Top Forums Shell Programming and Scripting Extract sequences of bytes from binary for differents blocks Post 302843787 by Ophiuchus on Thursday 15th of August 2013 05:49:25 AM

Hello ahamed,

The number of bytes are not constant between the start (0x32) and end (0xff 0x33)

The requested data is only inside each block:

I'm interested in:
1- The sequence in color inmediately after the beginning of each block, I mean after each 0x32 marked in red in image attached. These sequences always happens only once in each block.

2- Some of the sequences after the FF 34 in each block, these sequences not always happens but if happens only do once in each block. For example, in the sample file, the sequences after FF 34 only appear in block #2.

But maybe for now you can help with the sequences of item "1" and after that
I'll try to replicate the logic you use for sequences of item "2" or ask in order to be able to complete the 2nd item.

Thanks in advance for any help.

Regards

NAME
Palm::ToDo - Handler for Palm ToDo databases. SYNOPSIS
use Palm::ToDo; DESCRIPTION
The ToDo PDB handler is a helper class for the Palm::PDB package. It parses ToDo databases. AppInfo block The AppInfo block begins with standard category support. See Palm::StdAppInfo for details. Other fields include: $pdb->{appinfo}{dirty_appinfo} $pdb->{appinfo}{sortOrder} I don't know what these are. Sort block $pdb->{sort} This is a scalar, the raw data of the sort block. Records $record = $pdb->{records}[N] $record->{due_day} $record->{due_month} $record->{due_year} The due date of the ToDo item. If the item has no due date, these are undefined. $record->{completed} This is defined and true iff the item has been completed. $record->{priority} An integer. The priority of the item. $record->{description} A text string. The description of the item. $record->{note} A text string. The note attached to the item. Undefined if the item has no note. new $pdb = new Palm::ToDo; Create a new PDB, initialized with the various Palm::ToDo fields and an empty record list. Use this method if you're creating a ToDo PDB from scratch. new_Record $record = $pdb->new_Record; Creates a new ToDo record, with blank values for all of the fields. "new_Record" does not add the new record to $pdb. For that, you want "$pdb->append_Record". SOURCE CONTROL
