Neutronscott's solution is better as is supports any length string before the version and num values above 99

one enhancement is to deal with octal value using [icode[[bash#]num[/icode] syntax of ksh/bash, ie replace:
Code:
        zeroes=${num%%[!0]*}
        num=${num#$zeroes}      #remove leading zeros, or it uses octal
        num=$((num+1))

with:
Code:
    num=$((10#$num + 1))

cdxar(1)						      General Commands Manual							  cdxar(1)

NAME
cdxar - Read the Extended Attribute Record from a CD-ROM SYNOPSIS
/usr/bin/cdxar [-s number] [-b] file OPTIONS
Specifies the File Section for which the XAR is to be read. The numbering starts with one and number can be any whole number. If this option is not used, the last file section of the named file is assumed. Copies the entire XAR from a CD-ROM in binary format to standard output. Names a file or directory within the CD-ROM file hierarchy of a mounted CD-ROM File System. DESCRIPTION
The cdxar command accesses the Extended Attribute Record (XAR) associated with the File Section of a file or directory and lists its con- tents on standard output. The output is formatted in a table that contains the name of each field of the XAR and the corresponding contents of the entry as recorded on the CD-ROM. Note that the Application Use Field and the Escape Sequences are not listed because they may contain non-printable charac- ters. If the command is used without the -b option, only the fixed part of the XAR is copied from the CD-ROM. Users must have read permission for file in order to execute the command. EXIT STATUS
The following exit values are returned: The command was successful. The named file was not found, or was not within the CD-ROM hierarchy, or access permission was denied. The File Section indicated by -s does not exist. The File Section indicated by -s has no XAR. The File Section indicated by -s is not on the mounted CD-ROM. SEE ALSO
Functions: cd_cxar(3), cd_xar(3) cdxar(1)
