        NodeStore ns = session.store

        def aBuilder = nb
        for(p in PathUtils.elements(path)) {  aBuilder = aBuilder.getChildNode(p) }

        if(aBuilder.exists()) {
            aBuilder.remove()
            ns.merge(nb, EmptyHook.INSTANCE, CommitInfo.EMPTY)

            println "Node ${path} doesn't exist"
        }
    }
}

Same as rmNode() script but allows to delete multiple paths in one go.

Uses a file with multiple paths as input, which might have been created using childCount.groovy and paths filtered out using

grep "warning unable to read node " childCountOutput.txt | cut -b 29- > broken-paths.txt
