Below is my sample this1.json
[

"?xml": {
"attributes": {
"encoding": "UTF-8",
"version": "1.0"
}
}
},
{
"domain": [
{
"name": "mydom"

{
"domain-version": "12.2.1.3.0"
},
{
"server": [
{
"name": "AdminServer"
},
{
"ssl": {
"name": "AdminServer"
}
},
{
"listen-port": "12400"
},
{
"listen-address": "mydom.host1.bank.com"
}
]
},
{
"server": [
{
"name": "myserv1"
},
{

{
"name": "myserv1"

{
"login-timeout-millis": "25000"
}
]
},
{
"log": [
{
"name": "myserv1"
},
{
"file-name":
"/web/bea_logs/domains/mydom/myserv1/myserv1.log"
}

}

},
{
"server": [
{

{
"ssl": {
"name": "myserv2"

},
{
"reverse-dns-allowed": "false"
},
{
"log": [
{
"name": "myserv2"

{
"file-name":

The below code is able to extract file-name element from log array.
- hosts: localhost
gather_facts: no
vars:
json: "{{ lookup('file', './this1.json') | from_json }}"
tasks:
- name: display
debug:
msg: "{{ server.0.name }} -> {{ filename.0.log[1]['file-name'] }}"
loop: "{{ json[1].domain }}"
vars:
server: "{{ item.server | selectattr('name', 'defined') }}"
filename: "{{ item.server | selectattr('log', 'defined') }}"
when: item.server is defined and (item.server | selectattr('log',
'defined')) != []
On similar lines I wish to extract java-home element of server-start array.
Below is the code for the same:
- name: display CPATH
debug:
msg: "{{ server.0.name }} -> {{ cpath.0.'server-start'[2]['java-home']
}}"
loop: "{{ jsondata[1].domain }}"
vars:
server: "{{ item.server | selectattr('name', 'defined') }}"
cpath: "{{ item.server | selectattr('server-start', 'defined') }}"
when: item.server is defined and (item.server |
selectattr('server-start', 'defined')) != []
However, i get this error:
skipping: [localhost] => (item={'server': [{'name': 'myserv1'}, {'ssl':
[{'name': 'myserv1'}, {'login-timeout-millis': '25000'}]}, {'log':
[{'name': 'myserv1'}, {'file-name':
'/web/bea_logs/domains/mydom/myserv1/myserv1.log'}]}]})
fatal: [localhost]: FAILED! => {"msg": "template error while templating
string: expected name or number. String: {{ server.0.name }} -> {{
cpath.0.'server-start'[2]['java-home'] }}"}
I tried the following but none of them works:
msg: "{{ server.0.name }} -> {{
cpath.0.\"server-start\"[2]['java-home'] }}"
msg: "{{ server.0.name }} -> {{ cpath.0.server-start[2]['java-home']
}}"
msg: "{{ server.0.name }} -> {{
cpath.0.'[server-start]'[2]['java-home'] }}"
msg: "{{ server.0.name }} -> {{ cpath.0.[server-start][2]['java-home']
}}"
msg: "{{ server.0.name }} -> {{
cpath.0.['server-start'][2]['java-home'] }}"
None of this worked. Can you please suggest?
Note: This is just a sample json and the position of server-start may vary.
Hence using selectattr
