The event logs can be obtain via getReceipt for specific transaction. However, the data is not friendly.
How can i parse those topics , data and the event name ?
the receipt of a specific transaction can be that
>eth.getTransactionReceipt("0xd177dfaa34ac9292d16b550515be05ab1e4b3cdd12f9857e8842fbfc8f8d6794")

the topic field and data field is all in hex encode. It not friendly. How can i parse those hex string to get semantics value?
Besides, it is same to input field when an account sends a tx to contract. The input field like that
input:"0x797af627af036571d10c371233bfad0aa6eb1d38671b893d819d5fba2be2df2854ad92c8"
the first 4 bytes is the signature of the function and the rest of the data is the parameters of function. How can i make it more semantic
