Setting multiple CSV EXPORTER options is not documented on docs.basex.org
by Omar Siam 02 Oct '24

02 Oct '24

Hi, I just tried after some time to script a CSV export with a BXS file. I forgot how to set multiple options for the csv serialization. In the end this worked: <set option="EXPORTER">method=csv,csv=header=true,,lax=false,,quotes=true</set> I can not find it on docs.basex.org. Perhaps this should be added and explained.

Equivalent of eXist's util:wait in BaseX?
by Joe Wicentowski 28 Sep '24

28 Sep '24

Hi all, I'm retrieving content from a list of URLs with BaseX (via the http:send-request function) and appear to be hitting rate limits on the remote server. I'd like to pause for 5 seconds between requests. In eXist, I'd use util:wait [1] to handle this pause. Is there an equivalent in BaseX? Or is there a different approach in BaseX? Thanks!

Perfect. Cascaded function-calls through variables within self-recursive constructs work fine now. mvgr. Rob Stapper

Error with function-lookup and static variable
by Amanda Galtman 20 Sep '24

20 Sep '24

Hi, all. I'm seeing an error in BaseX when I use function-lookup in both a global variable and a function, where the function relies on the variable. I reduced the situation to the following small query: xquery version "3.1"; declare variable $local:lookup := function-lookup(QName("nonexistent", "nonexistent"), 1); declare function local:myfcn() { let $f := ($local:lookup, function-lookup(QName('http://www.w3.org/2005/xpath-functions','string'), 1))[1] return $f('a') }; local:myfcn() When I run it with BaseX 11.1, I get [XQDY0054] Static variable depends on itself: $local:lookup When I run it with Saxon-HE 12, I don't get this error. Is there anything I can do in my code to avoid this error? Thanks, Amanda

Unknown function db:open
by Kendall Shaw 18 Sep '24

18 Sep '24

I'm using basex 11.2 under WSL ubuntu 24.04 when I use the command xquery count(db:open('some')/*), I see an error message about db prefix being undefined. The same thing from an editor tab. import module namespace db = 'http://basex.org/modules/db'; count(db:open('some')/*) I get the same error message. Is this to be expected? How can I supply what is needed? Thanks, Kendall Shaw

Re: [basex-talk] terrible performance of webserver under BaseX11
by Christian Grün 10 Sep '24

(cc to the list) For a more helpful response, we would certainly need to look at your code and run it by ourselves. I recommend you to run your function… $SWM:dialog.new …outside your web application, e.g. in the BqseX GUI. This may help you to isolate the problematic part of the code.

terrible performance of webserver under BaseX11
by Rob Stapper 10 Sep '24

10 Sep '24

Hi Christian, My webserver-app that performed reasenably well under BaseX10 performs terribly under Basex11. Chrome even gives me at the end of the process an 'out of memory' message. So it is not only performance but also resource-usage. I have absolutely no clou how to address this, so all suggestions are very welcome. mvgr. Rob Stapper

Hi Christian, After the hollidaybreak I found the courage to try to port my application to BaseX's version 112. I get the error-dump shown below.

Alternatives to JTattoo in combination with BaseX GUI?
by Zimmel, Daniel 03 Sep '24

03 Sep '24

Hi, I noticed that JTattoo is no longer working properly with BaseX 11 (which is not a surprise because it looks like an abandoned project). I liked to use it to force a dark theme to the GUI. Does anybody know of alternatives? Are there any? Thanks, Daniel
