I need to be able to determine if an arbitrary node is or is not a database node.
I implemented this function:
declare function util:isDatabaseNode($node as node()) as xs:boolean { let $isDbNode as xs:boolean := try { let $nodeId as xs:integer? := db:node-id($node) (: let $msg := prof:dump(``[[DEBUG] relpath:isDatabaseNode(): nodeId: "`{$nodeId}`"]``) :) return exists($nodeId) } catch * { (: let $msg := prof:dump(``[[DEBUG] relpath:isDatabaseNode(): Got exception `{$err:code}` - `{$err:description}`]``) :) (: return :) false() } let $msg := prof:dump(``[[DEBUG] relpath:isDatabaseNode(): Returning `{$isDbNode}``]``) return $isDbNode };
With the prof:dump() calls commented out as shown here, it always returns true, even when it returned false.
If I comment in the prof:dumps then I get the expected correct false result.
This must be the result some optimization at compile time but I haven’t been able to find a construction of this function that works without the debug messages.
Is there a better way to determine if a node is a database node?
This is with 10.6.
Cheers,
