pretty_print for attributes

[Hubbitus]

Hello.

I have tomcat context file which looks like:

<?xml version='1.0' encoding='utf-8'?>
<Context>

    <Resource type="javax.sql.DataSource"
              name="jdbc/UniDataDataSource"
              description="UniData Database"
              factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
              driverClassName="org.postgresql.Driver"
              url="jdbc:postgresql://localhost:5432/unidata"
              username="postgres"
              password="postgres"
              initialSize="10"
              maxActive="100"
              maxIdle="50"
              minIdle="10"
              suspectTimeout="60"
              timeBetweenEvictionRunsMillis="30000"
              minEvictableIdleTimeMillis="60000"
              testOnBorrow="true"
              validationQuery="SELECT 1"
              validationInterval="30000"
              removeAbandoned="true"
              removeAbandonedTimeout="180"
              logAbandoned="true"
              abandonWhenPercentageFull="50"
              jdbcInterceptors="ResetAbandonedTimer" />

</Context>

I want change their attributes, but do not loose formatting. Is it possible?

My playbook similar to (simplified):

    - name: Provide database access to tomcat
      xml:
        file: context.xml.default
        pretty_print: True
        xpath: /Context/Resource[@name='{{item.name}}']
        attribute: "{{item.attribute}}"
        value: "{{item.value}}"
      with_items:
        - { name: 'jdbc/UniDataDataSource', attribute: url, value: 'test_attribute_value' }

And result in one string:

<?xml version='1.0' encoding='UTF-8'?>
<Context>
  <Resource type="javax.sql.DataSource" name="jdbc/UniDataDataSource" description="UniData Database" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" driverClassName="org.postgresql.Driver" url="test_attribute_value" username="postgres" password="postgres" initialSize="10" maxActive="100" maxIdle="50" minIdle="10" suspectTimeout="60" timeBetweenEvictionRunsMillis="30000" minEvictableIdleTimeMillis="60000" testOnBorrow="true" validationQuery="SELECT 1" validationInterval="30000" removeAbandoned="true" removeAbandonedTimeout="180" logAbandoned="true" abandonWhenPercentageFull="50" jdbcInterceptors="ResetAbandonedTimer"/>
</Context>

I understand what it is Resource tag with many attributes and no child elements. It there any possibility preserve formatting similar to initial state?

The xml module is upstream now (and ships with Ansible v2.4).

Please close this issue, and if needed, open a new issue at: https://github.com/ansible/ansible/issues

Yeah, so this is going to be hard to do unless we would hook output-rules to lxml somehow. But you would need to codify the different style-rules the output should consist of. Not sure if lxml can do it, and which ones we would implement, but I am open to add it.

Feel free to migrate this issue to: https://github.com/ansible/ansible/issues
