Ruby: Hash Assignment/Parse from Text

Programmer Question

Looking to create a hash table from a text output that looks like this (whitespace between words are tabs):

GCOLLECTOR     123456     77889     uno  
BLOCK     unique111    error     fullunique111     ...     ...     ...  
DAY     ... ... ...  
LABEL     detail     unique111     Issue     Broken - The truck broke  
LABEL     detail     unique111     Folder    3c1  
LABEL     detail     unique111     Datum     bar_1666.9  
GCOLLECTOR     234567     77889     uno  
BLOCK     unique222    error     fullunique111     ...     ...     ...  
DAY     ... ... ...  
DAY     ... ... ...
LABEL     detail     unique222     Issue     Broken - The truck broke  
LABEL     detail     unique222     Datum     bar_9921.2
LABEL     detail     unique222     Folder    6a3  
GCOLLECTOR     345678     77889     uno  
BLOCK     unique333    error     fullunique111     ...     ...     ...    
LABEL     detail     unique333     Datum     bar_7766.2
LABEL     detail     unique333     Folder    49k  
LABEL     detail     unique333     Issue     Broken - The truck broke

I would like to create a hash table that assigns each of the following to the hash:

gcollectors = Hash.new

gcollectors = { "UniqueID" => uniqueXXX,

"Datum" => bar_XXXX.X,

"FullUniqueID" => fulluniqueXXX,

"IssueGroup" => Broken

}

The uniqueXXX fields always match for the BLOCK and associated LABELs.

I am having a couple issues:

1- How do I assign just those fields to the hashes?

2- How can I split the text prior to the hyphen (in LABEL ... Issue) and assign it to IssueGroup?

3- How can this be done reliably when the order of the LABEL lines is different?

.. same question for when there are multiple DAY lines or no DAY lines.
