I think really you are wanting to validate against a particular schema.
This is entirely unrelated to which namespace URI is used to identify
elements in the document. You can have multiple XML Schema Documents
(xsd) for validating XML documents whose elements are "in" the same
namespace.

A namespace in XML is nothing more or less than a URI used as a name.
They don't actually "do" anything :)

http://docs.basex.org/wiki/Validation_Module#XML_Schema_Validation
has an example that might help.

Can you elaborate on what you were imagining doing with namespaces? An XML 
namespace is referred to by it’s URI. If you created one, I don’t know what it 
would mean to tell the code later on which to use.

Do you mean a namespace prefix?

 XML schema.  I've got a record definition created by IBM that

Re: [basex-talk] Startup hooks or persisting jobs

[Kendall Shaw]

Thanks. I would think that being able to schedule jobs would fit nicely with 
having scheduled jobs persist after restart.

Subject: AW: Startup hooks or persisting jobs

Hi Kendall,

there is currently no way to do this using BaseX itself. But I also don’t think 
that should be the job of BaseX. Instead you can write a servlet and deploy it 
using Tomcat which runs some Java application, e.g. which could trigger some 
BaseXX command. See 
http://crunchify.com/how-to-run-java-program-automatically-on-tomcat-startup/
 for an example how to do this.

Cheers
Dirk

Betreff: [basex-talk] Startup hooks or persisting jobs

Am I missing an existing way to run xquery at startup (basex web service 
running under tomcat)? I have jobs that I schedule, but I have to schedule them 
again if basex is shutdown.

I can test for basex being started outside of basex and then execute queries, 
but if there is already a way to do this within basex, I would rather do that.

Re: [basex-talk] using apply-function within an updating function

[Michael Seiferle]

Hi Rob,

may I ask what you intented to do? Looks like you expect $dataRec to contain 
exactly one value, right? 
At least I think so because you called `db:create#1` in `fn:apply` which 
implies you expect the array to contain a single value.

To create a single database use:

> ```
>   db:create($dataRec => array:get(1))
> ```

…or… if you want to create a database for each of the array values:

> for $db in ($dataRec => array:flatten()) (: Flatten array to a sequence :)
> return db:create($db).(: create one database per 
> array item :)

…and… last but not least, for "Dynamic Updating Function Invocation“[1] you 
might use:

> let $create  := db:create#1
> for $db in ($dataRec => array:flatten())
> return invoke updating $create($db)

I could not wrap my head around using array:for-each(#2) and dynamic updating 
function invocation; this could make for a more readable solution, but I can 
not seem to get the syntax right; if we already fully support it at all ;-)


I hope I did not get you all wrong, feel free to ask for more help! ;-)

Best
Michael

[basex-talk] using apply-function within an updating function

[r . stapper]

Hi,

I want to use the apply function within an updating webfunction, see[1]
How can this be done?

TIA,

Rob Stapper

[1]
declare
  %rest:path("/cFactBank/dbCreate")
  %rest:PUT("{$dataRec}")
  %input:json("format=map")

  %updating
  function _:cFactBank.dbCreate
  (  $dataRec as array(*)
  )
  {
apply( db:create#1
 , $dataRec
 )
  } ;
