Subject: [Usergroups] How to xquery multiple xml files?
Message-ID: <BANLkTimT8eQXScrS1Ma3bg1hX7gPsCw8-A@mail.gmail.com>

Hi,

   I am a new one in xquery and marklogic.
   I have a question about how to xquery and aggregate informations for
multiple xml files.

   That is, I have several files put in "/my", that is "/my/prods1.xml",
"my/prods2.xml" and so on.

   And I want to write a xquery to sum the prod's amount whose price
is greater than 10.
   It is a little like:

  let $prods := doc("/my/*")/products/product[price>10]
  return sum($prods/amount)

  (Of course the doc("my/*") cannot work.)

  How can I achieve this?

Thanks.

Good luck!
