Modify XML Configuration if Condition is Met - Ansible
Hi I am new to ansible and I have to write a script for deployment where an artifact will be dropped in a folder and it's package is referenced from an XML config file. I am able to do the first part and it works just fine but the second part is challenging me where I have to edit the conf file and add a child element there. It is written like this:
- name: Configure Artifact Properties
- xml:
path: '{{ server_home }}/conf.xml'
xpath: /Server/SupportedArtifactTypes
add_children:
- NewArtifact
ArtifactName: HelloWorld
ArtifactPackage: org.HelloWorld
Now this will work fine the first time but when I am going to rerun it in the next deployment cycle, its going to add the child element again which should not be happening. Does anybody have a clue how can we modify the task so that the configuration is added only if it does not exist?

According to the Ansible XML documentation, you can perform a count against xpath matches. Try doing a count of the xpath first and register the result. Make your task execute when the count is less than 1.
- name: Check for existing artifacts in SupportedArtifactTypes
- xml:
path: '{{ server_home }}/conf.xml'
xpath: /Server/SupportedArtifactTypes
count: yes
register: hits
- name: Configure Artifact Properties
- xml:
path: '{{ server_home }}/conf.xml'
xpath: /Server/SupportedArtifactTypes
add_children:
- NewArtifact
ArtifactName: HelloWorld
ArtifactPackage: org.HelloWorld
when: hits.count < 1
Give this a try and see if it helps!
