    Hi,

    I am looping all the nodes in a map with c.findAll().each { n -> ... } and I would like to know if it is possible to know what is the current node's depth level?

    Thanks,

    Alexandre

    I did a function that returns a nodes' depth:

            def getNodeDepth(pNode, level) {
            if (pNode.parent == null)
                return level
            else
                getNodeDepth(pNode.parent, ++level)
            }

    Usage:

    myDepth = getNodeDepth(node, 0)

    Always call with '0' as the second parameter.

    You could also use the builtin node.getNodeLevel or node.pathToRoot. This is especially handy in formulas:

    = "this node's level is " + node.getNodeLevel(false)
= "this node's level is " + (node.pathToRoot.size() - 1)

    Thanks Volker I didn't know that function, I replaced my code.
