regex - Grep for multiple words in log files

I have file which has contents
like:

--------------------------------
service=serviceX
time=100ms
PARAMS={"data"=>"{\"id\":1,\"items\":[{\"quantity\":1,\"name\":\"itemName1\"

            ,\"quantity\":2,\"name\":\"itemName2\"}]}
------------------------------------------------

            --------------------------------
service=serviceX

time=200ms
PARAMS={"data"=>"{\"id\":2,\"items\":[{\"quantity\":2,\"name\":\"itemName3\"

            ,\"quantity\":2,\"name\":\"itemName4\"}]}
------------------------------------------------

            --------------------------------
service=serviceX
time=300ms
PARAMS={"data"=>"{\"id\":3,\"items\":[{\"quantity\":1,\"name\":\"itemName5\"

            ,\"quantity\":2,\"name\":\"itemName6\"}]}
------------------------------------------------

I
am trying to find all the items in listed in the file.
My query looks like

grep -o 'name\\":\\"[^\\]*\\"' |
            tr -d '\\"'

and the
output
is

name:itemName1
name:itemName2
name:itemName3
name:itemName4
name:itemName5
name:itemName6

I
want the output
like:

id:1
name:itemName1
name:itemName2
id:2
name:itemName3
name:itemName4
id:3
            
name:itemName5
name:itemName6

I
am new to linux and not sure how to grep for multiple words in a single
query.
