community.general.xml:

path: config.xml

xpath: /security-config/parameters/init-param

add_children:

- init-param:

param-name: logout.url

param-value: http://google.com

<init-param>

<param-name>invalidate.session.exclude.list</param-name>

<param-value/>

<init-param param-name="logout.url" param-value="http://google.com"/></init-param>
