[basex-talk] how to insert attribute?

[積丹尼 Dan Jacobson]

http://docs.basex.org/wiki/XQuery_Update mentions insert attribute.
So how can I insert attribute?

$ cat x.xq
copy $c :=
  <entry>
    <title>Transform expression example</title>
    <author>BaseX Team</author>
  </entry>
modify (
  replace value of node $c/author with 'BaseX',
  replace value of node $c/title with concat('Copy of: ', $c/title),
  insert node <author>Joey</author> into $c,
  insert attribute Z {'B'} into $c/title,
)
return $c
