update depth?
by Graydon Saunders 28 Apr '26

Hello! If I try to get rid of nested inline markup with no attributes let $test as element() := <p>First <span><span><span>word</span></span></span> was excited.</p> return $test update {(.//span[empty(@*)]) ! (replace node . with ./node()) } I get <p>First <span><span>word</span></span> was excited.</p> Which tells me (or at least I think it tells me) that the outermost replace happens last and the result is replacing the outer span with its node children. I'm not getting free recursion by matching all the span elements. What I want is <p>First word was excited.</p> where all the span elements with no associated attributes unwrap. Is there a plausibly elegant way to do this? (Stacking the same update several times works, and a fully recursive typeswitch approach works, but I can't avoid thinking there's a better way.) Thanks!

BaseX 12.3: xml:id namespace lost when loading XInclude document
by Jonathan Robie 28 Apr '26

28 Apr '26

I am hitting a namespace bug when loading XInclude files with -i. I am using BaseX 12.3. Consider the following two files: main.xml: <?xml version="1.0"?> <root xmlns:xi="http://www.w3.org/2001/XInclude"> <xi:include href="included.xml"/> </root> included.xml: <?xml version="1.0"?> <item xml:id="test123"/> If I load main.xml with -i, the xml namespace is lost on xml:id attributes: basex -i main.xml '//item/@xml:id' This returns empty. But if I load it using doc(), it works fine: basex 'doc("main.xml")//item/@xml:id' This returns test123. My workaround is to use doc() with an external variable instead of -i. This may be related to issue #2642. Jonathan

BaseX UI main window class name - SunAwtFrame
by ykhabins＠bellsouth.net 23 Apr '26

23 Apr '26

Hello, I have quite an unusual request. BaseX UI has a main window class on a source code level. Would it be possible to rename its current main windows class name, i.e. SunAwtFrame, to something else? For example, BaseXUI or BaseXFrame, to make it unique. Here is a context of my request. I am using "Dark Mode Any App" to apply a dark mode for the BaseX UI: https://darkmodeanyapp.com/ "Dark Mode Any App is a simple utility which allows you to apply a dark mode filter to any Windows application, even when it does not natively support dark mode." Unfortunately, both BaseX and Oxygen XML IDE are using the same main windows class name: SunAwtFrame. It is causing a conflict between BaseX and Oxygen XML IDE for the "Dark Mode Any App" utility. It cannot distinguish between them. The dark mode is being turned on for both apps at the same time. Which is not an intended result. Thank you in advance. Regards, Yitzhak Khabinsky

Inconsistent behavior when trying to use @*:id instead of @xml:id ?
by Orderic-Vital Pain 21 Apr '26

21 Apr '26

Hello, So we came across a strange behaviour while building a webapp with BaseX and aren’t sure if it’s a bug or an edge case we can’t wrap our heads around. I’ll try to explain it the best I can, with basic examples attached. First some context: - our app needs to fetch xml fragments stored in a database (one db per app instance) which can contains anywhere from 1 to X document(s) - these xml documents can be encoded in xml-TEI (which use attribute @xml:id) or xml-ead (which use @id) ; we plan to add support for more xml vocabularies in the future and thus can’t presume whichether attribute is used - so far we’ve used a function which checks for both attributes by writing it as `@*:id`, similar to the attached query `query2` Now here’s the problem : this doesn’t seem to work to fetch element with an @xml:id attribute if and only if: - the document containing the target node only has 1 namespace declared in an @xmlns attribute (see `doc1a` and `doc1b`) - AND the document is the only one in the database we’re trying to fetch from Here are the tests we conducted before reaching out to you: - `doc1a` and `doc1b` are identicals, and contain only 1 namespace encoded in an @xmlns attribute - `doc2` is the same as them except it has 2 (identical) namespaces, one declared in an @xmlns attribute and the other in @xmlns:ns - `query1` search for specific(s) <div> using `@xml:id='div2'` - `query2` is the same but writes it as `@*:id='div2'` - If we search in doc1a (OR doc1b) ALONE, query1 find the searched <div> [test1] but query2 fails [test2] - If we search in doc2 ALONE, both query1 and query2 find the searched <div> [test3 and test4] - If we search in any combination of 2 or more of these documents, both query1 and query2 find the searched <div> [test5 and test6] This as been tested with BaseX versions 10.7, 11.7 and 12.2, both in our webapp and on the GUI – to the same result each time. Attached is a basex script which reproduce these tests. So as I said, we’re not sure why it would do that – failing with 1 doc but working with 2 or more ? In any case we can build around that (by writing eg. `[@*:id or @xml:id]`), we’re just curious to know if it’s working as intended and if yes, if there is more to this that we should know of. Thank you for your time. Best regards, O.-V. Pain

changed "function-look"-behavior in BaseX version 12.3
by Rob Stapper 21 Apr '26

21 Apr '26

Hi, Version 12.3 now requiers the module where the function is fetched from, to be imported in the same module as where the "function-lookup"-function is called from. Before this wasn't the case, the module only needed to be imported in the module where the qName for the function is created. So I could have a module for generic function retrieval. Those days seem to be over. Is this behaviour to stay or can it be reversed. (app.xqm) import module namespace c = "_function-lookup-test.c" ; import module namespace m = "_function-lookup-test.m" ; c:method( xs:QName( "m:test") , 0 )() (m.xqm) module namespace m = "_function-lookup-test.m" ; declare %public function m:test( ) { "test"} ; (c.xqm) module namespace c = "_function-lookup-test.c" ; (: Basex 12.3 requiers the lookup-module to be imported in the module that executes the 'function-lookup'-function in previous versions this was not necessary, the-lookup-module only needed to be imported in the calling module, here: "m.xqm" import module namespace m = "_function-lookup-test.m" ; (: not working anymore since 123 when not active :) :) declare %public function c:method ( $qName as xs:QName , $arity as xs:integer ) as function(*)? { function-lookup( $qName , $arity ) otherwise message( "WARNING!: Method not found: " || xs:string( $qName) || "#" || $arity ) } ; Best.

Can not set HTTP status message in response anymore comparing 10.6 to 12.3
by Omar Siam 20 Apr '26

20 Apr '26

Hi list, I just started to update my error reporting library [1] to 12 and XQuery 4.0. This used HTTP messages in previous versions to report the exact kind of problem the server encountert. It relies on this snippet working: declare %rest:path("response_message") function api:response_message() { (web:response-header( {}, { 'Cache-Control': 'max-age=3600,public' }, { 'status': 200, 'message': '*Something else*' } ), "Something else") }; To my surprise this does not show "Something else" as the HTTP status message. curl -i http://localhost:8984/response_message HTTP/1.1 200 *OK* Server: Jetty(12.1.8) Date: Fri, 17 Apr 2026 15:45:09 GMT Cache-Control: max-age=3600,public Content-Type: application/xml; charset=UTF-8 Server-Timing: parse;dur=5.49 ms,compile;dur=0.68 ms,optimize;dur=0.01 ms,evaluate;dur=0.00 ms,serialize;dur=0.00 ms Content-Length: 14 Something else As setting the HTTP status message to anything is a rather obscure feature, I would say updating the docs and stating, that this no longer works would "solve" this error. The last version I tested this with and it worked is 10.6 (probably any version running in Jetty 9.4).

I allready adjusted my software. So no need there. Just wondering if function-lookup behaviour is changed by design. Cheers. Rob Stapper

A basic FUSE implementation for BaseX
by josef-a-thorne＠pm.me 17 Apr '26

17 Apr '26

Hello all, I've decided to share a small project that I hacked together which was useful for me in my work with BaseX. I found myself wanting to sometimes edit documents in BaseX by hand in my favorite editor without having to export and re-import them. With the deprecation of the WebDAV module, I wrote a basic FUSE filesystem to temporarily replace it for my use cases. I share it in the hope that others might find it useful, though it is rather messy C code. https://github.com/Josef-Thorne-A/basex-fuse/tree/main I heard that there was a FUSE implementation for BaseX in the past, but was unable to dredge up any source code. I also have been working on some EMacs modes for working with BaseX/modern XQuery, but they are not yet polished enough to be worth sharing at large. If there are any other brave EMacs-BaseX users would like to see it though I would be happy to share it with them privately if they message me. – Josef Thorne

Issue with function namespaces in BaseX v12.3?
by Amanda Galtman 16 Apr '26

16 Apr '26

Hi, BaseX team. I tried to use BaseX 12.3 with XSpec to test Schematron schemas with Andrew Sales's XQS implementation. I ran into an error. [XPST0017] Unknown function: true (similar: fn:true). I am not sure if the underlying issue is coming from BaseX or XQS or both. I simplified the query that reproduces the error, but the query still relies on XQS. I briefly tried to reproduce the problem without XQS but haven't been successful yet. Reproduction steps are in the GitHub issue that I created in the XQS repo. Does it ring a bell with any BaseX experts? https://github.com/AndrewSales/XQS/issues/87 Thanks, Amanda
