node-basex
by kleist-digital 08 Apr '16

Hi Andy, me again. Just saw, that you’ve also written a node-based Basex-Client. My frontend is a node-app. So far I’m using AJAX-calls, to communicate via the REST-Interface with the Basex-Server, in generell I use the run command to execute different queries. Are there any advantages (disadvantages) to change to a classical Server-Client Scenario (performance, less resources, security)? You know, I want to use it in an OpenShift-Environment for the future. Thanks for any advice. Günter

XQUERY3 option
by George Sofianos 08 Apr '16

08 Apr '16

Hello, I wonder if there is any way at the moment to run scripts with xquery version 1 only. I can't find a way to set XQUERY3 option to false. I have some scripts that fail to run (process runs forever) with BaseX and I want to see if the version is causing this. I have set xquery version "1.0" encoding "UTF-8"; as the first line of my script, but it doesn't seem to do anything as well. Also is there any way to see where BaseX is consuming so much time/processing power? I can use a profiler but It's not easy to see what part of the script is causing this huge delay. Thanks.

Symlinked files with RESTXQ
by Lars Johnsen 08 Apr '16

08 Apr '16

Dear all What must be done to access symlinked files when using BaseX as http server? The scenario is that a fairly large collection of audio-files are accessed using BaseX which serves them up over http. However, it seems that symlinking (the folder with audio files exists as a symlinked copy in the static directory of the BaseX web folder) prevents the browser from accessing them. Is there a parameter in the settings I have overlooked? Best, Lars G. Johnsen National Library of Norway

Hi Christian, thanks for the tipp. I haven't noticed the files so far at all. I will have a closer look and I think a lot of questions :) Günter P.S.: Sorry for the second email, I didn't send it to the list. > > > >> Am 07.04.2016 um 17:55 schrieb Christian Grün <christian.gruen(a)gmail.com>: >> >> Hi Günter, >> >> This is just a quick reply, but you could have a look at the DBA >> XQuery code embedded with BaseX.

Hi Marco, your approach sounds great. It would be a very, very great help, to see some snippets :-) so the picture becomes more clear for me.

Hi, If I install HelloWorld.jar to the repository as described at [1] It all works. However attempts to remove the item generate: [bxerr:BXRE0001] Package 'org.basex.modules.Hello' does not exist. /Andy [1] http://docs.basex.org/wiki/Repository#Java

XLSX to XML
by Florian Eckey 07 Apr '16

07 Apr '16

Hi guys, are there any ideas how to convert excel's xlsx (not xls) files to xml with XQuery or to use a Java library which can be imported? It looks like BaseX has no internal functions as for instance MarkLogic. Any ideas or example implementations to do that in XQuery or Java? Best, Florian

Is XdmItem going to move out of tests to be part of the API at some point? Kendall

Issue with db:add via restxq in 8.4.2
by Vincenzo Cestone 06 Apr '16

06 Apr '16

Hi guys, in the new basex 8.4.2 version I cannot write on the db via restxq. For example if you create an empty 'testdb', set in the .basex conf file the option MIXUPDATES = true, and call the '/dbaddtest' restxq implemented as in the following: --- module namespace o = "test"; declare %rest:path("/dbaddtest") %rest:GET function o:dbaddtest() { let $o := db:add('testdb', <aaa/>, '111.xml') return <ok/> }; --- it will not work in the basex 8.4.2 i.e. the document is not added to the db, but it will return <ok/> without errors. On the contrary the db:add executed in the BaseX.jar client is working well. And also the above restxq code is working as expected in the basex 8.3.1 version. Thank you in advance. Regards, Vincenzo

Function as argument
by Paul Swennenhuis 06 Apr '16

06 Apr '16

Hi all, I am now using functions as argument in BaseX for the first time, borrowing the way to do that from some old list archive contribution. Apparently you have to use the name of the function followed by #1 like this: let $a := local:someFunc($nodeSet, local:someOtherFunc#1) But it is unclear to me if this is indeed the right way to do it. The #1 suggests that there may also be a #2, #3 etc. (and possibly a #0). I could not find the documentation on using functions as argument on the Wiki pages. (I am happy to see that it works as expected though) Paul
