I want to parse the following text and find lines that start with `'+'` or `'-'`:

```
--- a/product.json
+++ b/product.json
@@ -1,4 +1,4 @@
 {
-  "name": "Coca Cola",
-  "barcode": "41324134132"
+  "name": "Sprite",
+  "barcode": "41324134131"
 }
\ No newline at end of file

```

When I find a such line, I want to store the attribute name. I.e., for:

```
-  "name": "Coca Cola",

```

I want to store `name` in `minus_array`.
