Description

For example,
I want to find the root of a node tree that contains a node with a specified id. The child node may be n layers deep in the node tree. In my specific case, I know how deep it is so

//element(*, my:foo)[bar/*/*/*/*/@jcr:uuid = 'abc']

finds the node of type my:foo that contains the child node with id 'abc'.

Now, I would like to generalize this so I thought i could simply do the following.
//element(*, my:foo)[bar//*/@jcr:uuid = 'abc']

but this does not work.
