Hi Lukas and Andy. The use of wildcards solved the issue and I see now why BaseX stated that it couldn't find the insertion point. Thanks again! C.

Adding a wildcard to the name test (.../*:two) should do the trick. Your final insert query then looks like this: insert node <three/> into db:open("MyDB", "q471pa0lnovkfflso7ecsd6nj1.xml")/*:one/*:two If the problem persists just get back to us. Hope this helps, have a nice day, Lukas On Mon, Jul 8, 2013 at 1:49 PM, Carlos MARCOS LAGUNAR <carlos.marcos@atosresearch.eu> wrote: Hi, I'm working with latests BaseX distribution. The problem arises when I change from a specific namespace to a default namespace on the XML file. From that moment on the insertion becomes messy, since some of them fail. Example: Here is the source XML that I insert into the newly created DataBase: <n:one xmlns:n="oneone"> <two /> </n:one> I execute then a xquery to insert a node into the empty tag "two": insert node <three/> into db:open("MyDB", "q471pa0lnovkfflso7ecsd6nj1.xml")/*:one/two In that case, I get a successful insertion: If I query the file (db:open("MyDB", "q471pa0lnovkfflso7ecsd6nj1.xml")/*:one) I get: <n:one xmlns:n="oneone"> <two> <three /> </two> </n:one> This is the normal behavior. The problem comes when I try to set that namespace as the default. So I create a new DataBase with the following XML: <one xmlns="oneone"> <two /> </one> When I try to execute the same xquery as before (insert node <three/> into db:open("MyDB", "q471pa0lnovkfflso7ecsd6nj1.xml")/*:one/two) I get the following error: rg.basex.core.BaseXException: Stopped at line 1, column 84: [XUDY0027] Insert target must not be empty I cannot understand then why the namespace affects the insertion this way :-/ I'm querying and insertion from a Java application by using JavaClient, although I guess this is not relevant here. Any help would be appreciated.
