Re: [Exist-open] eXistDB sequence generator?

[Michael W. <wes...@ja...>]

Hi Gary,

See the "counter" module built into eXist.

  let $dummy := counter:create('file-ids')
  let $new-file-path := xmldb:store("/db/docs",
concat(counter:next-value('file-ids'), '.xml'), $doc)

  let $dummy := counter:destroy('file-ids')


Hope this helps.

Take care.
