      Currently it is empty (i.e. all attributes will be copied). -->

Hello @shlomco, welcome to the Community!

I was able to obtain the results you expect with this new version of your code:

- name: Forum PB
  hosts: localhost
  gather_facts: false
  tasks:

    - name: Task 1.1
      community.general.xml:
        path: debug/xml/config.xml
        xpath: /security-config/parameters
        add_children:
          - init_param: ""

    - name: Task 1.2
      community.general.xml:
        path: debug/xml/config.xml
        xpath: /security-config/parameters/init_param
        add_children:
          - param-name: "logout.url"

    - name: Task 1.3
      community.general.xml:
        path: debug/xml/config.xml
        xpath: /security-config/parameters/init_param
        add_children:
          - param-value: "http://google.com"

Results:

<?xml version='1.0' encoding='UTF-8'?>
<security-config>
    <parameters>
        <!--only
        basic authentication available-->
        <init-param>
            <param-name>authentication.type</param-name>
            <param-value>os_authType</param-value>
        </init-param>
        <!-- Invalidate session on login to prevent session fixation attack -->
        <init-param>
            <param-name>invalidate.session.on.login</param-name>
            <param-value>true</param-value>
        </init-param>
        <!-- Add names for session attributes that must not be copied to a new session when the old
        one gets invalidated. Currently it is empty (i.e. all attributes will be copied). -->
        <init-param>
            <param-name>invalidate.session.exclude.list</param-name>
            <param-value />
        </init-param>
        <!-- NEW PARAMS -->
        <init_param>
            <param-name>logout.url</param-name>
            <param-value>http://google.com</param-value>
        </init_param>
    </parameters>
</security-config>

$ ansible-playbook -i localhost fourm_pb.yml

Just play around with it, you might add more than one children at once:

https://docs.ansible.com/ansible/latest/collections/community/general/xml_module.html#parameter-add_children

Another approach to achieve this would be using jinja2 templating:

https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_templating.html

Hope it helps!
