BaseX 12.4: The XML Prague Warmup Edition
by Christian Grün 28 May '26

28 May '26

Hi all, We’ve released BaseX 12.4. It comes a bunch of new built-in XQuery functions for running queries in parallel (for-each, fork-any, reduce), for improved string similarity operations (ngrams, token set/sort ratio), new binary functions for counting & settings bits, atomic creation of databases with binary & value resources, improved encoding detection and streaming when creating ZIP archives and numerous more tweaks. Some more details: XQUERY FUNCTIONS - XQuery Module, parallelization: for-each, fork-any, reduce - String Module: new functions for ngrams & token set/sort ratio - Binary Module: bin:rotate, functions for counting & settings bits - Database Module, DB creation: support for binary & value resources - Archive Module: improved encoding detection, better streaming XQUERY PERFORMANCE - index rewritings for numeric predicates: //city[@code = 12763] - evaluate loop-invariant predicates only once - faster sorting of primitive value sequences - callback functions: improved type propagation FIXES & TWEAKS - command-line: newline added after the result of a query - error feedback: improved 'did you mean' suggestions - parsing of CSV files with empty lines - GUI: higher trace output limits For a preview of the added features, please visit the following page: https://docs.basex.org/13 Visit our homepage to download the latest version: https://basex.org Christian BaseX Team

Error parsing query, related to qualified name of function
by Amanda Galtman 28 May '26

28 May '26

Hi, BaseX team. An XSpec user found an error when running a particular test with BaseX. I reproduced the error in its original form, and I also shrunk the reproduction steps to obtain a similar error. The small, self-contained reproduction steps in BaseX 12.2, 12.3, or BaseX124-20260521.170507 are: xquery version "3.1"; declare namespace pfx = "some-uri"; declare function pfx:namespace-node() { 'some result' }; declare function pfx:my-fcn() { Q{some-uri}namespace-node() }; pfx:my-fcn() Error message: [XPST0003] Expecting '}', found '('. It points to the end of the qualified function name Q{some-uri}namespace-node. The error does not occur if I call the function using a prefix pfx:namespace-node() or if I change the function's local name. The original reproduction steps are in https://github.com/xspec/xspec/issues/2354 . In that context, the error does not occur if I change the function's local name in both the XQuery module being tested and the XSpec test file. Thanks, Amanda

Access to the Unicode Character Database from XQuery?
by Graydon Saunders 25 May '26

25 May '26

Hello! I am currently exploring what to do when a footnote callout, which will wind up in an xs:ID value, is something like U+2020 DAGGER; one obvious way is to use the character name. (So instead of an @id value of `Fn1` I'd have `Fndagger` or similar.) I see that the current draft of XPath 4.0 has new-since-3.0 `characters()` and `grapheme()` functions, but so far as I may tell it does not have a way to get UCD properties for a codepoint. Is there an XQuery (or BaseX) way to do this? Thanks! Graydon

Strictre type checks on RestXQ
by Marco Lettere 21 May '26

21 May '26

Hello all, I have a code similar to [1] and used to call it like: curl -X POST "https://myservice.local?compress=false". It worked. Yesterday I moved to official Basex 12.3 version and started getting the following error: *Value of 'compress' must be of type xs:boolean, supplied: "false". (hint: ....)* Is this a recent implementation change that enforces this type-check? I've not been able to identify the changes in the code base. Apparently, I can fix this by changing 'false' to false() in the annotation but do you have any idea whether this will be back compatible to older basex versions? Thanks! Marco. [1] declare %rest:path("store") %rest:POST %rest:query-param("compress", "{$compress}", 'false') %rest:produces("application/xml") function _:store($compress as xs:boolean) { () };

Running 2 BaseX instances on same machine
by Liedtke, Alexander 18 May '26

18 May '26

Hello everyone, I have a question installing two instances on the same machine. Does anybody have a recommendation for an installment, especially in regards on where to set/configure the ports (/home/basex/.basex file, start parameters, jetty.xml, etc.) for the secondary instance ? I am using debian 13. BaseX is started as normal user. Goal is to setup a system that works similar to Solr replication. Data is planned to be synched with rsync - or does there exist some kind of replication I did oversee? Many thanks for any tips on this topic. Best regards Alexander Liedtke

Error handling according to the server protocol
by Ben Engbers 18 May '26

18 May '26

Hi, I am currently busy writing C wrapper functions around the public functions from my libBasexCpp library (see https://github.com/BenEngbers/libBasexCpp) In doing so, I discovered an imperfection in that library and an ambiguity in the server protocol. The description of the command protocol states that in the event of an error, the server response consists of {partial result} {error} \01. However, at the bottom of the description of the Query protocol, it is stated that the server response ends with a \01, followed by an error string. In the current implementation, I assumed that all successfully executed requests end with a \00 and that a \01 at the end means an error has occurred. My question is whether this assumption is correct or whether I need to adjust my implementation so that the \01 is followed by the error message? Ben

XQuery update in Basex GUI
by Ben Engbers 11 May '26

11 May '26

Hi, While improving my C++ test application for the libBasexCpp library, I tried to execute this line: update insert <Line_1 line="1">Content 1</Line_1> into doc('/TestCppClient/Test.xml')/root This resulted in a crash. And since I only know the basics from XQuery, I wanted to use the GUI for debugging this instruction. Even in the GUI this line could not be executed. I consulted Mistral/leChat and it came to the conclusion that probably I haven't enabled the XQuery Update facility. But in the GUI I don't see how I could enable the update facility. I am using linux/Fedora with standard open-jdk. Should I install additional jar-files? Ben -- Ben Engbers Grietjeshof 77 6721 VH Bennekom +31 6 23634840
