AEM - How to restrict a template from showing in a certain path

问题

I wonder if someone has achieved what I'll post here. In order to allow a template to be created under a certain path, there is a flag allowedPaths that receives a regex.

So, if I want my template "test" to appear only under /content/www/xx/xx/test-templates and child elements, I can do this:

/content/www/.*/.*/test-templates(/.*)?

But what if I want to make the opposite? I want the template "test" to appear in every /content/www/xx/xx/ node and beyond, EXCEPT /content/www/xx/xx/test-templates and children?

I have tried several ways but no luck so far. Do you have some hint regarding this?

Thanks!

You can always restrict a more generic pattern with a lookahead. Here is an expression that should work for you:

^(?!/content/www/[^/]*/[^/]*/test-templates(?:/|$))/content/www/[^/]*/[^/]*(/.*)

See demo.

• ^ - matches the start of string
• (?!/content/www/[^/]*/[^/]*/test-templates(?:/|$)) - makes sure the next substring is not /content/www/<some_node>/<some_node>/test-templates, followed by the end of string ($) or /
• /content/www/[^/]*/[^/]*(/.*) - matches /content/www/<some_node>/<some_node> followed with optional / and zero or more characters other than a newline
