Alfresco: Add a tag based on the location of the document

[robinho]

I've been struggling with a little script that should be easy to implement: I've added a rule on a folder that runs a script. The script should get the folderlocation of the uploaded or incoming document and add the location as a tag:

var url = document.properties.locale.nodeRef;
document.addTag(url);
‍‍‍‍

It should be something like this, but this doesn't work. how should I do it?
Is it possible to get the folder-structure of the file as a tag?

thanks

You can get a node's path by

document.getQnamePath()
or
document.getDisplayPath()

Although you can ,but I dont'think it is a good idea to set folder-structure as a tag.
