# JsonParser
2+
JsonParser is simple JSON parsing library, you can parse JSONObject or JSONArray using path and key. Simply you just need to pass the name of the object or object key and index number of the array item in your path.
3+
4+
## Installation
5+
6+
This JsonParser JAR add in the `lib` folder then after set in build path. Download JAR form this link [JsonParser_DLab_1.1.jar](Release/JsonParser_DLab_1.1.jar&raw=true). For, the more information refer this [`JsonParser`](src/main/) sample project.
7+
8+
## Path
9+
Path is combination of the object key and index number of the array item.
10+
11+
`Dpath=[menu/items/12/label]`
12+
13+
here, `menu` `items` `label` is your object key and 12 is array item index number now, the question arises how to parse using this path so let's little talk on it. When you give path to the library, it is converted path to token then after, first check is JSONObject or JSONArray if object then token must have key value(if not found then it is throwing exception and process break) then after this process recursively doing till your path's all token finished, once token finished then process break and return the result in the Object format.
14+
15+
> Note : Array index is starting from the 1 so, your array first item index is 1.
16+
17+
### Example:
18+
19+
You can refer more example [here](src/main/JsonParserTest.java),
20+
21+
```json
22+
{"menu": {
23+
"header": "SVG Viewer",
24+
"items": [
25+
{"id": "Open"},
26+
{"id": "OpenNew", "label": "Open New"},
27+
null,
28+
{"id": "ZoomIn", "label": "Zoom In"},
29+
{"id": "ZoomOut", "label": "Zoom Out"},
30+
{"id": "OriginalView", "label": "Original View"},
31+
null,
32+
{"id": "Quality"},
33+
{"id": "Pause"},
34+
{"id": "Mute"},
35+
null,
36+
{"id": "Find", "label": "Find..."}
37+
]
38+
}}
39+
```
40+
41+
## Key
42+
Key is a unique element of the object so, duplication of the key is not allowed in the object but whole JSONObject or JSONArray may be have same name key.
43+
44+
`Dkey=[value]`
45+
46+
here, `value` is your key and more then one time if it exists in the whole object then during this recursively process, if key found then notify the user on `onValueFound(String key, Object value)`.
47+
48+
### Example:
49+
50+
You can refer more example [here](src/main/JsonParserTest.java),
51+
52+
```json
53+
{"menu": {
54+
"id": "file",
55+
"value": "File",
56+
"popup": {
57+
"menuitem": [
58+
{"value": "New", "onclick": "CreateNewDoc()"},
59+
{"value": "Open", "onclick": "OpenDoc()"},
60+
{"value": "Close", "onclick": "CloseDoc()"}
61+
]
62+
}
63+
}}
64+
```
65+
66+
```java
67+
new JsonParser().addObserver(new OnValueObserver() {
68+
@Override
69+
public void onValueFound(String key, Object value) {
70+
System.out.println(String.valueOf("Find By Key : " + value));
71+
}
72+
73+
}).inFind(GetJson.strJson_4, "Dkey=[value]");
74+
75+
// Output :-
76+
// Find By Key : New
77+
// Find By Key : Open
78+
// Find By Key : Close
79+
```
80+

83+
### End User
84+
85+
* QA Engineer, Developer and who not like to do manually parsing of the JSONObject and JSONArray.
86+
* How I get the idea to develope this type of library, when I am helping to the one of the my QA friend in his automation process that time, I observed that he man facing trouble on the parsing of the JSONObject then I decided to develop this type of library, which have structure as like selenium Xpath.
87+
88+
89+
### Current issues
90+
91+
* Integer key value of object's is not supported
92+
* Only JSONObject or JSONArray as string passing in the arguments
93+
* multiple path is not supported
94+
* array of key or array or path not supported as arguments
95+
* always need listener as a notifier
96+
97+
