Hi Namrata, 

< snippage>

In Mathematica, the notation is {7,6} ....

Really?  What did you try?  You may have been close to a solution, but who
can tell since there is no code ....

Anyway, it's not particularly efficient but

inpu = OpenRead["test.txt"]
data = ReadList[inpu, Record, RecordSeparators->{"%Object Name : left asis",
"%Object Name : right asis"}];
data = Flatten[data]
proc = ReadList[StringToStream[#], Table[Number, {6}]]& /@ data
proc = Partition[Flatten[proc], 6]

Works for me.  

Another version might use Find to skip over the problematic records and yet
another might export the first data record to yet another file & Import it.
