jmeter json path Conditional Extraction at peer level - jmeter

Question

I'm using jmeter v2.13 and jp#gc - JSON Path Extractor.
Here is my JSON sample:
{
"views": [{
"id": 9701,
"name": " EBS: EAS: IDC (EAS MBT IDC)",
"canEdit": true,
"sprintSupportEnabled": true,
"filter": {
"id": 55464,
"name": "Filter for EBS: EAS: IDC & oBill Boar",
"query": "project = \"EBS: EAS: IDC\"",
"owner": {},
"canEdit": false,
"isOrderedByRank": true,
"permissionEntries": [{
"values": [{
"type": "Shared with the public",
"name": ""
}]
}]
},
"boardAdmins": {}
},
{}
]
}
Is it possible to extract views[x].id where there exists an entry views[x].filter.permissionEntries[*].values[*].type that equals Shared with the public?
How would I do it?
Thanks

Answer 1

JSON Query would look like this (I admit I didn't try it in JMeter)
$.views[?(#.filter[?(#.permissionEntries[?(#.values[?(#.type == "Shared with the public")])])])].id
Explanation:
We expect under root ($) to have views and for it to have property id. The rest (in []) are conditions to select only views items based on predefined condition. Hence $.views[conditions].id
Conditions in this case are coming one within the other, but main parts are:
We define condition as a filter ?(...)
We ask filter to look under current item (#) for a specific child item (.child), child may have its own conditions ([...]). Hence #.child[conditions]. That way we move through filter, permissionEntries, values
Finally we get to field values and filter it for a child type field with particular value Shared with the public. Hence #.type == "Shared with the public"
As you see it's not very intuitive, and JSON path is a bit limited. If this is a repetitive issue, and your JSON is even more complicated, you ay consider investing into a scriptable pre-processor (similar to the one explained here.
