The normal XPath query for this would be something like this:


Unfortunately Jackrabbit doesn't support the child node axis in XPath
predicates (see JCR-247), which means that the above query will not

I can't think of a simple workaround to this issue, so my solution
would be to run a query like //*[@value='test'] and post-process the
results with:

    while (iterator.hasNext()) {
        Node node = (Node) iterator.next();
        Node parent = node.getParent();
        if (parent.getPrimaryNodeType().isNodeType("type")) {
            // process parent node

Another solution would be to redesign the node type structure to match
the limitations of the Jackrabbit query capabilities.
