[Monetdb-developers] Data type of the text() nodes
by Ying Zhang 01 Jun '07

01 Jun '07

Hello, I'm having a problem with the data type of text() nodes in XRPC implementation. --------------------------- module function definition: --------------------------- module namespace foo = "xrpc-test-function"; declare function foo:q2($strs as xs:string*) as node()* { for $s in $strs return <bar>{$s}</bar> }; ----------- test query: ----------- import module namespace test = "xrpc-test-function" at "/ufs/zhang/max-nr-params/xrpc-mod.xq"; let $hello := <hello> <lang>en</lang> <lang>nl</lang> </hello> let $lang := $hello/lang/text() return execute at {"localhost"} {test:q2($lang)} ------------------------------------------------------------- I got the error "function could not be resolved" when I run the XRPC query above. The reason is that all items in the sequence $lang have the type U_A (xs:untypedAtomic), and they are marshalled in the XRPC req. msg as, for example: <xrpc:atomic-value xsi:type="xs:untypedAtomic">en</xrpc:atomic-value> At the server side, the values are unmarshalled and assigned the type U_A again. So far, the values are handled correctly, IMHO. But then problem happens, namely, when the server calls the function 'xquery_sig_match' (in pathfinder.mx), it concludes that xs:untypedAtomic is not a sub-type of xs:string, hence, the function signature can not be resolved. This error does not occur if the function 'q2' is called without XRPC. So, what is the trick of pathfinder to match the signature? Is xs:untypedAtomic just treated the same as xs:string? The easiest solution of my problem is to just marshall an xs:untypedAtomic as an xs:string, but if someone has better suggestions, I would like to know. Thanks a lot! Regards, Jennie

[Monetdb-developers] xs:docmgmt in XQuery user defined functions?
by Djoerd Hiemstra 01 Jun '07

Dear all, Just a small suggestion for the release version. New functions like pf:add-doc() return an item of type docmgmt. However, this type does not seem to exist if I try to use user defined functions such as declare function local:weird( ) as xs:docmgmt { pf:add-doc("weird.xml", "weird.xml") }; gives > use of undefined type: at (14,38-14,47): ``xs:docmgmt'' Similarly with "docmgmt" or "pf:docmgmt", etc. Or if I use "item()" > type error: body of local:weird() evaluates to `docmgmt' which is not > a subtype of `item' Best, Djoerd.
