    Actually sorry for not providing full information now I edited so please help me with that. I am not storing in a hash.

      The basic process is still the same. You record what you have seen and make processing decisions based on that data.

      doSomething($data) unless $seen{$key}++

      Providing appropriate values for $key, doSomething(), and $data are left as an exercise for the reader.

      Update: Perhaps I am misunderstanding your question. Please post what you expect to see as output given the provided input data.

        Sorry still you didn't understand my problem I think, In the above input data as I provided, in that data number tag is same in first data node and third data node, but reaming information is different only number tag is same. I need to delete the entire node if number tag element is same in any node. I am printing $info into new file so before printing into new file I need to eliminate duplicate nodes by using number tag. I hope now you understand clearly, I posted my expected result also. can you suggest me.
