how to analysis the txs from the block query?

[yytany]

when i query the blcok txs from the interface

func (c *baseRPCClient) Block(ctx context.Context, height *int64) (*coretypes.ResultBlock, error) {
	result := new(coretypes.ResultBlock)
	if err := c.caller.Call(ctx, "block", &coretypes.RequestBlockInfo{
		Height: (*coretypes.Int64)(height),
	}, result); err != nil {
		return nil, err
	}
	return result, nil
}

i get the tx with hex just like

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

above all, it seem that the block contains the raw tx . but i don't know how to decode it.

just could cross query tx get the tx info ,but the speed is slowly.so i want one block just query once .
