Merge two files by condition

I have two files as below
A file
Code:
/* comment for id1 */
"id1" = "x1"

/* comment for id2 */
"id2" = "x2"

/* comment for id3 */
"id3" = "x3"

B file
Code:
/* comment for id1 */
"id1" = "y1"

/* comment for id2 */
"id2" = "x2"

I hope output file as below
Code:
/* comment for id1 */
"id1" = "y1"

/* comment for id2 */
"id2" = "x2"

/* comment for id3 */
"id3" = "x3"

Condition looks like
1. All comment lines in A file will output
2. if same comment line in B file, line below that comment line in B file will output
3. if no same comment line in B file, line below comment line in A file will output

Does anyone help me?
