A JCR query will always return nodes (also accessible as "rows"). See
the QueryResult.getNodes() and QueryResult.getRows() method.

Your query could look like this; it will return all nodes that have a
rep:principalName property with a value:

//element(*,rep:Group )//*[@rep:principalName]

(BTW, @jcr:score is not a standard property, it is used for ordering,
so you could append " order by @jcr:score" to the query above).

Now you would retrieve the property through the QueryResult, for example:

NodeIterator nodes = queryResult.getNodes();
while (nodes.hasNext()) {
    String name = nodes.nextNode().getProperty("rep:principalName").getString();
}


Hope that helps,
Alex
