Hi friend below is my sample output from a regsiter name dataInfo

ok: [123.23.44.123] => {
    "msg": [ 
        {
            "changed": true,  
            "item": [
                {
                    "artifactName": "helloWorld.jar", 
                    "status": "false" 
                }, 
                "myGroup1"
            ], 
            "rc": 0,
            "stderr_lines": [], 
            "stdout": "ok", 
            "stdout_lines": [
                "ok"
            ]
        },
        {
            "changed": true,  
            "item": [
                {
                    "artifactName": "helloWorld.jar", 
                    "status": "false" 
                }, 
                "myGroup2"
            ], 
            "rc": 0,
            "stderr_lines": [], 
            "stdout": "ok", 
            "stdout_lines": [
                "ok"
            ]
        }

Below is my code

- name: My ArtifactName Name
  debug:
    msg: "artifactName = {{ item.item[0].artifactName }}"
  loop: "{{ dataInfo.results }}"
  when: item.changed | bool == true and item.stdout == "ok"

How can i only display as below

artifactName = helloWorld.jar

rather than

artifactName = helloWorld.jar
artifactName = helloWorld.jar

I have shared my code as shown above. Please advice

As you are looping with dataInfo.results, the debug message will repeat for each "item". If you only want unique artifactName, then you can save it to a variable using json_query and choose to display only unique ones.

Something like this:

    # Save list of artifactName found in dataInfo.results even with duplicates
    - name: save artifact names
      set_fact:
        artifact_names: "{{ artifact_names | default([]) + [ item | json_query('item[].artifactName') ] }}"
      loop: "{{ dataInfo.results }}"
    # Show each item of artifact_names using unique filter to eliminate duplicates
    - name: show unique artifact names
      debug:
        var: item
      loop: "{{ artifact_names | flatten | unique }}"

Update:

Below set_fact:

artifact_names: "{{ artifact_names | default([]) + [ item.item[0].artifactName ] }}"

... will work if you get only 1 hash in item like this:

            "item": [
                {
                    "artifactName": "helloWorld.jar", 
                    "status": "false" 
                }, 
            ],

But if it may have multiple hashes like below, it won't work:

            "item": [
                {
                    "artifactName": "helloWorld.jar", 
                    "status": "false" 
                }, 
                {
                    "artifactName": "someother.jar", 
                    "status": "false" 
                },
                ...
            ],

If this is a possibility, then json_query should be used. It can be used exactly like the jq command.
