[xquery-talk] namespace questions

[Marc Van Cappellen]

I would expect this to result in

  <foo>

     <sam:bar xmlns:sam="http://www.aaa.aaa/a"/>

     <huhu:ele xmlns:huhu="http://www.aaa.aaa/b">text</huhu:ele>

  </foo>

 

You might want to check with the implementer of the XQuery engine you're using?

> Hello,

> I have difficulties in using namespaces in xquery.

> To create an xml-document like this:

> <foo xmlns:sam="http://www.aaa.aaa/a"  xmlns:huhu="http://www.aaa.aaa/b"

>     <sam:bar/>

>     <huhu:ele>text</huhu:ele>

> </foo>

> I use the follwing xquery:

> 

> declare namespace sam="http://www.aaa.aaa/a";

> declare namespace huhu="http://www.aaa.aaa/b";

> let $extern := <a namespace="huhu"/>

> return

>    <foo>

>     <sam:bar/>

>     {element {concat($extern/@namespace,":","ele")} {"text"}}

>     </foo>

> 

> <foo>

>     <sam:bar/>

>     <huhu:ele>text</huhu:ele>

> 2. If the second line  (declare namespace huhu=http://www.aaa.aaa/b"; is

> name:huhu). If the prefix "huhu" of the namespace is not known in advance,
