Hello all. I have a file that looks like this: 

Hostname1     1.1.1.1     Cisco
              Chassis Serial Number xyz123
              Interface Gig0/0/31
Hostname2     2.2.2.2     Juniper
              Chassis Serial Number abc123
              Interface Gi-0/0/31

The repeating pattern seems obvious. Each row starts with either text that starts at the beginning of the row (i.e. hostname which could be the key to a hash), or the row starts with white space or tabs and then some text which could be the values associated with the key of the hash (i.e. serial number, interface, etc..). I have been working on solving this to parse through files with a Perl program but I've failed so far. I was hoping the Perl community might have suggestions to help me grasp what seems like should be a simple concept.
