Thanks, but don't think this helps. The problem is that i need a function like declare function t:getIdByName($arg) { let $x := collection($dbName)/module//object[@name = $arg] return if( empty($x/@id) ) then "-1" else $x/@id }; But as I understand, BaseX doesn't have runtime query optimization, that's why this variant works too long. I thought, indexes could help to solve this problem. 2012/6/4 Christian Grün <christian.gruen@gmail.com>
Hi Alex,
but how can I get objects in my data base that contain these indexes?
just use ordinary XPath/XQuery expressions, such as..
db:open('db')//*[@* = 'id152429']
You can also directly retrieve text and attribute nodes, e.g. as follows [1]:
db:attribute('db', 'id152429')
Hope this helps, Christian
