Re: Descendant-or-self

[Marcel Reutegger]

Hi Alvaro,

as per XPath specification [1] your query will be expanded to:
/descendant-or-self::node()/myTopNode/descendant-or-self::node()/*

which will effectively match only descendant nodes of /myTopNode

what you are probably looking for is:

//myTopNode/descendant-or-self::node()

but this is currently not supported by jackrabbit because it is not 
required by the JCR spec.

Hi list,

I have been doing some tests with "//" (descendant-or-self) axis, and i 
think is not interpreted correctly by Jacrabbit Query Builder.
A query with this axis returns only "descendant" nodes instead of 
"descendant-or-self" nodes. For example with this piece of code:

       Node myTopNode = 
rootNode.addNode("myTopNode");                             
myTopNode.addNode("subNode");              
myTopNode.addNode("subNode");              rootNode.save();
       String query = "//myTopNode//*";
       //Should find all the 3 nodes: myTopNode and 2 subnodes.
       QueryManager qm = currentSession.getWorkspace().getQueryManager();
       Query q = qm.createQuery(query, Query.XPATH);
       QueryResult qr =  q.execute();                             
NodeIterator nodes = qr.getNodes();
       assertEquals(3, nodes.getSize());

the test fails because it only finds two nodes instead of three. Is this 
a bug? Am I misunderstanding "//" axis?

Regards,
