I have a field "dimension" with values:

dimension=InstanceIdentifier=[aaamcehjcdbp01]
dimension=InstanceIdentifier=[aaamcehgcdbp01]......and many more,

I want aaamcehjcdbp01 from this field as new field.

host=aaamcehjcdbp01 
host=aaamcehgcdbp01

Please help me with the regex or any other method.
