Hi All , i have to save the XMLs files from the DB but i am not able to do that below is my code, this code is generating only one kb file so can any one tell me where i am doing wrong
let $localpath := 'D:/2017/doctest/xmls'
for $xmls in db:open('test')
return file:write($localpath,$xmls,map{"method": "xml"}) Note: i am able to do using import command but i don't have to copy all data from the DB i have to copy by URI Thanks & Regards Dharmendra Kumar Singh

You only provide a path to file:write whichbgets overwritten by each for-loop, so you end up with just one file with the contents of the last run of the for-loop. You should instead provide a file name for each file you want to write. 6. juuli 2017 1:42 PM kirjutas kuupäeval Dharmendra Singh <dharam.mahi at gmail.com>:

Thanks for your reply Kristian So I gone through the documentation and I found that function file:write take parameters path and item so first parameters I am passing the local directory path where documents has to be saved and second argument I am passing the item It will be very helpful if you provide the example

Hello, this is a mistake our students do many often: -------- 1. (:1- One file with all entries:) 2. file:write('D:\myBase.xml', <bdd>{for $x in /bdd return $x}</bdd>) ------- 1. (:Many files with one entry each:) 2. for $x at $count in //entry return file:write('D:\'||$count||'.xml', $x) ------- Br 2017-07-06 20:06 GMT+02:00 DK Singh <dharam.mahi at gmail.com>:

Hi Mr.SALVADOR, I got the solution what i was looking for:
let $dbpath  := '/test/'
let $files := fn:uri-collection($dbpath)
let $count := fn:count($files)
let $zip   := archive:create(
                           $files ! element archive:entry { . },
                           $files ! bin:encode-string(fn:serialize((fn:doc(.))))
                           )
return file:write-binary('D:\2017\doctest\xml.zip', $zip) Thanks and Regards Dharmendra Kumar Singh
