I want to list all leaves ids where group name is i.e. "group110"
So, output for this example is 014, 288, 223 and 244. 

Here is content of my JSON file:

```
{
 "name": "visualization",
 "children": [
        {
         "name": "group100",
         "children": [
                {
                 "name": "group110",
                 "children": [
                        {
                         "name": "group111",
                         "children": [
                                        {"id":"014","link":"-","name":" Animals/70","decade":"-"}
                                ]
                        },
                        {
                         "name": "group112",
                         "children": [
                                        {"id":"288","link":"-","name":"Heidelberg platen press","decade":"1960s"}
                                ]
                        },
                        {
                         "name": "group113",
                         "children": [
                                        {"id":"223","link":"-","name":"Camera Praktica Super TL – shutter release","decade":"1960s"},
                                        {"id":"244","link":"-","name":"Mechanical calculator, Facit","decade":"1950s"}
                                ]
                        }
                        ]
                },

```
