Is it possible to map multiple attributes using Jinja/Ansible?

I would like to build an output that shows the key and value of a variable.

The following works perfectly ...

# Format in Ansible

msg="{{ php_command_result.results | map(attribute='item') | join(', ') }}"

# Output
{'value': {'svn_tag': '20150703r1_6.36_homeland'}, 'key': 'ui'}, {'value': {'svn_tag': '20150702r1_6.36_homeland'}, 'key': 'api'}

What I would like is to show the key and svn_tag together as so:

I'm able to display either the key or svn_tag but getting them to go together doesn't work.

msg="{{ php_command_result.results | map(attribute='item.key') | join(', ') }}"

# Output
ui, api

However, this is what I want.

# Desired Output
api - 20150702r1_6.36_homeland
ui - 20150703r1_6.36_homeland

You can do it by using the following techniques:

1. Create filter_plugin. Add filter_plugins = <path to the folder> in ansible.cfg. Then create a file say my_plugin.py:

   class FilterModule(object):
   ''' Custom filter '''
       def filters(self, my_arg):
          return <parse it here......>
   

Example:

playbook.yml

---
- hosts: localhost
  gather_facts: no
  connection: local
  tasks:
    - set_fact: 
        php_command_result:
          results: {'value': {'svn_tag': '20150703r1_6.36_homeland'}, 'key': 'ui'}
    - debug: msg="Hey look what I got '{{ php_command_result.results | a }}'"

my_plugin.py

import json

class FilterModule(object):
    def filters(self):
      return {'a': a}

def a(a):
  r = '%s - %s' % (a['key'], a['value']['svn_tag'])
  return r

2. Fast and easy approach: just use python/php/shell or what ever you prefer with shell module. Something like this:

   - name: Pars output
     shell: python -c "import json; json.loads('{{ php_command_result.results }}') ....
