I will need to get whole sentence of b and f and ignore b that are not related to f.

Expected output : 

b=54 y=0x23 arg=0x78 def=0x2 val=0x65b
f chk.fin.reg.m_cwr 0x213

b=40 y=0x90 arg=0x34 def=0x5 val=0x2197
f ref.grf.pin.clk_trg 0x0021

from the b sentence, I will need to get y, arg, def. from f sentence (naming - chk.fin.reg.m_cwr, ref.grf.pin.clk_trg)

 
Ex: 
From b :
y = 0x23
arg = 0x78
def = 0x2

From f : 
chk.fin.reg.m_cwr
