recursively used variables
by Rob Stapper 12 Aug '24

12 Aug '24

Hi, The code[1] below and send as attachment generates a error message: “Static variable depends on itself: $Q{http://www.w3.org/2005/xquery-local-functions}test”. I use these variables to refer to my private functions in my modules so I can easyly refer to them in a inheritance situation. It’s not a big problem for me but I was wondering if the error-triggering is justified or that it should work. [1]=========================================== declare variable $local:test := local:test#1 ; … [View More]

28 Mar '24

Hi, I have a C# .net application on my local machine, I have started the BaseX server and I want to use BaseX in my .Net application but as soon as I want to create a Session: Session session = new Session("localhost", 1984, "admin", "admin"); I also tried with no username and password but it is the same result. I get an "Access Denied". What am I missing? Thanks in advance, Stephane ________________________________ IMPORTANT NOTICE: This message may contain confidential or privileged … [View More]

BaseX and NFS
by Marco Lettere 20 Mar '24

20 Mar '24

Dear all, we have an instance of BaseX running on top of an NFS exported disk. Yes yes I know it's not the best possible scenario thus I was expecting a slight performance decrease. Anyway, when comparing local disk to NFS disk, for a tiny operation like storing a very small document into a database (without optimize or indexes) we get orders of magnitude of difference. And I'm saying from few hundreds of ms to several seconds in some cases. Does anyone have experience with cases … [View More]

Out of Main Memory
by Murray, Gregory 15 Mar '24

15 Mar '24

Hello, I’m working with a database that has a full-text index. I have found that if I iteratively add XML documents, then optimize, add more documents, optimize again, and so on, eventually the “optimize” command will fail with “Out of Main Memory.” I edited the basex startup script to change the memory allocation from -Xmx2g to -Xmx12g. My computer has 16 GB of memory, but of course the OS uses up some of it. I have found that if I exit memory-hungry programs (web browser, Oxygen), start … [View More]

validate:xsd() questions
by Murray, Gregory 11 Mar '24

11 Mar '24

Hello, What is the default value of the “cache” option for the validate:xsd() function? The default doesn’t seem to be indicated in the documentation for that function. Also, the following code raises an error message saying “Item expected, empty sequence found” but that seems odd since the second argument to validate:xsd() is supposed to be optional, thereby telling the validation process to fall back to using the schema indicated in the document itself. let $options := map {'cache' : true()… [View More]

xslt:transform-report result
by Andy Bunce 11 Mar '24

11 Mar '24

Hi, Using BaseX 9.7.1 and saxon9he-9.9.1.jar The documentation suggests the ?result from xslt:transform-report should be *a* document-node where possible [1] This seems not quite to be the case when there are processing instructions or comments at the top level. In these cases a sequence of document-nodes is returned. /Andy [1] https://docs.basex.org/wiki/XSLT_Module#xslt:transform-report let $xslt:=<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0"> … [View More]

Troubles with ft:mark
by Jack Steyn 07 Mar '24

07 Mar '24

Hi BaseXers, Consider the following query run on a database 'factbook' containing factbook.xml with full-text indexing: declare function local:search( $database as xs:string, $query as xs:string ) { let $country-search := ft:search($database, $query)/ancestor::country let $city-search := ft:search($database, $query)/ancestor::city/ancestor::country let $other-search := ft:search($database, $query)/parent::*[name() = ('ethnicgroups', 'languages')]/ancestor::country let $… [View More]

Inconsistent behavior for root context in BaseX GUI
by Thompson, Timothy 06 Mar '24

06 Mar '24

I’ve been noticing an inconsistent behavior in the GUI with BaseX 11 beta (build 17d8426). I have a simple query on a database created from a CSV file. Sometimes it works, but sometimes the root context is evaluated as an empty sequence: - rewrite context value: . -> () - rewrite util:root(nodes): util:root(()) -> () I notice this when I open the database as context and try to execute the query. After the query fails, if I try to click on the “home” icon in the result panel, it also … [View More]
