Restore from Backup: Should it work to restore backup from system A on system B?
by Eliot Kimber 09 Jul '25

09 Jul '25

Using BaseX 11.6 on RHEL 9, I created a backup of a database on system A, copied the zip to my personal machine, then used the DBA upload and restore to recreate the database on the new server. I verified that the Zip has the expected data files, so it looks legit. The database is created but no data is loaded, so the database shows 0 bytes. Should this load have worked? I can also just scp the database from one server to the other if that is reliable, or just unzip the zip on the target server—should that work? Cheers, E. _____________________________________________ Eliot Kimber Sr. Staff Content Engineer O: 512 554 9368 servicenow servicenow.com<https://www.servicenow.com> LinkedIn<https://www.linkedin.com/company/servicenow> | X<https://twitter.com/servicenow> | YouTube<https://www.youtube.com/user/servicenowinc> | Instagram<https://www.instagram.com/servicenow>

Problem (BaseX 12) serializing a map with json:serialize() in combination with the http-client module
by Andreas Hengsbach | nexoma 08 Jul '25

08 Jul '25

Hi everyone, I have found a problem when serializing a map to JSON. I use the following map as request body for the http-client: map { 'username' : "aaa", 'password' : "bbb", 'grant_type' : 'password' } => json:serialize() In 10.4 everything works fine. In 12.0 this now leads to an error when I send the request. (Response from service: <code type="number">400</code><message>Invalid json message received</message>) It seems that the request body is being escaped twice when interacting with the http client. If I omit json:serialize(), it works fine in BaseX 12. I would expect json:serialize() to recognize the map(*) data type and serialize it correctly. Best regards Andreas

Bug related to copy/modify/return and java binding
by Andreas Hengsbach | nexoma 08 Jul '25

08 Jul '25

Hello everyone, I have probably found a bug that is related to copy/modify/return and the java-binding. Anyway, I couldn't narrow down the problem any further. With the following XQuery-Code I get the result “<A>0</A>” in BaseX 10.4 - as expected. In BaseX 12.0 I get an error message “Cannot invoke ”org.basex.query.func.XQFunction.arity()“ because ‘func’ is null”.

Upgraded from V9.7.3 to V12, problem in xQuery search when node has a blank line
by shripal＠orior.in 07 Jul '25

07 Jul '25

Dear All, I upgraded from v9.7.3 to v12 and all my queries are giving an error because of a simple problem. This is my XML: <xml><number integer="0"><number></xml> xQuery: for $b in //*[@integer] where $b = '' return replace value of node $b with '0' The above works without problems. It puts a zero and this is the result: <xml><number integer="0">0</number></xml> BUT if there is a CRLF in the <number> node it does not replace the node with a 0. <xml><number integer="0"> <number></xml> Now the same query does not work in v12. It works in v9.7.3, so I have had to downgrade. All my queries where I am looking for a blank node have stopped working. Could you please show me some option using which I can ignore the CRLF and continue searching for blank nodes the way I used to be in the past ?

Hello, Congrats on the BaseX 11.9 release! Installed it, and started to run my XQuery tests. Right away I got the following error: "Property 'http://www.oracle.com/xml/jaxp/properties/entityExpansionLimit' is not recognized." Both doc() and collection() are tripping on it. A full repro is below. XQuery #1 ============================================= declare variable $base_dir as xs:string := 'e:\Temp\'; for $docx in collection($base_dir) return $docx XQuery #2 ============================================= declare variable $base_dir as xs:string := 'e:\Temp\'; for $file in file:list($base_dir, false(), 'books*.xml') let $docx := doc($base_dir || $file) return $docx Regards, Yitzhak Khabinsky

Fulltext processing, "window selection"
by Hans-Juergen Rennau 30 Jun '25

30 Jun '25

Dear BaseX people, it seems to me there is a bug concerning full text processing. The following expression basex "'a single event during the custodial history of a manuscript or other object.' contains text 'custodial history of a manuscript' all words window 5 words" yields "false", shouldn't it yield "true"? Only when I enhance the window width to 10, I get true. 10 would be the required window length if the window started at the beginning of the string. But I think the window should start at the first and end at the last of the words, so 5 should suffice. With kind regards,Hans-Jürgen

Execute an Query function from Java code
by Mauro Mugnaini 24 Jun '25

24 Jun '25

Hi all, I’m trying to invoke an XQuery function (instance of FItem) from a Java class that acts a callback listener for a Java client adapter. I’m able to instantiate and register it in a query module by using the Java bindings, passing the reference to the XQuery code to invoke) but at the moment that the function is invoked a QueryContext instance is needed (or at least the current Context to create it if I understood correctly) of the running BaseX service (an HTTP server in my case). I tried to find a way to do that taking a look of the Jobs module and similar packages in the source code but without success. In the “Java" examples it is shown how to do this for code invoked during a query execution in a class that is a subclass of the QueryModule and by using the ContextDependent annotation that do the job automatically. It is not my case since the code is not directly call during a query execution but asynchronously in a separate thread. Finally my questions: It is something that is possibile to do? Is there some singleton I can access or other classes I can use to achieve that? Thanks and regards. Mauro

csv:doc - interpretation of option values
by Hans-Juergen Rennau 24 Jun '25

24 Jun '25

Dear BaseX people, a small observation, which might be regarded as a bug (perhaps not). It is about the interpretation of options passed to function csv:doc. I set the 'header' option like this: let $options := map{'header': //header/data()} with the confusing result that the option is ignored, although the comparison $options?header eq 'yes' yields true. If I replace data() with string(), let $options := map{'header': //header/string()} the option works as expected. Kind regards,Hans-Jürgen

Confirming presence of icu4j
by Joe Wicentowski 16 Jun '25

16 Jun '25

Hi all, I have a query that makes use of the UCA collation with the "numeric" keyword [1] (e.g., for ensuring that "d2" sorts before "d12"), and I'm seeking a way to confirm that the icu4j library is available on the BaseX classpath before I run queries that depend on it. [2] Even though I manually install the icu4j library into Basex's lib/custom directory as specified in [3], I have sometimes forgotten to do so when, for example, Homebrew upgraded BaseX, and as a result my query relying on this collation began producing unexpected results. I've tried to make use of the XQuery 4 fn:collation-available function [4], but so far I've been unsuccessful. Specifically, using BaseX 11.9 or 12 with icu4j-77.1.jar on macOS 15.5 (on Apple Silicon), the following expression returns the expected result: ``` ("d2", "d12") => sort("http://www.w3.org/2013/collation/UCA?numeric=yes") ``` The result, as expected, is ("d12", "d2"), when the library is present and the opposite when it is absent. But the following version, which introduces a conditional and the fn:collation-available function, always takes the "else" path: ``` if (collation-available("http://www.w3.org/2013/collation/UCA?numeric=yes", "compare")) then ("d2", "d12") => sort("http://www.w3.org/2013/collation/UCA?numeric=yes") else "UCA collation not present" ``` I expected this expression to return ("d12", "d2") but instead received "UCA collation not present". Am I misusing/misunderstanding how to use fn:collation-available? Thanks! Joe [1] https://www.w3.org/TR/xpath-functions-31/#uca-collations [2] https://docs.basex.org/main/Full-Text#collations [3] https://docs.basex.org/main/Startup#full_distributions [4] https://docs.basex.org/12/Standard_Functions#fn:collation-available

Manual database lock
by Matt Dziuban 12 Jun '25

12 Jun '25

Hello everyone, Is there any function or command I can use to manually lock and unlock a database? Based on the documentation on File-System Locks <https://docs.basex.org/12/Transaction_Management#file-system_locks> it sounds like maybe just creating an upd.basex file in the database directory would be sufficient? Thanks in advance, Matt

Result too large with Full Text Index
by Yann de Thézy 11 Jun '25

11 Jun '25

Hello, I encounter what seems to be a bug with the use of Full Text Index (basex 11.9). I have created a database with FTINDEX (and CASESENS + DIACRITICS). When I call once a function in the xquery below, the result is different than when I call it twice. It seems that the whole database is searched in the case of 2 calls which is not what is expected. Xquery is : declare function local:getHit($documents, $word) { (# db:enforceindex #) { $documents//*[text() contains text {$word}] } }; let $docs := collection() let $docsSmall := for $doc in $docs where $doc/book/@category='COOKING' return $doc let $a := trace("res 1 : " || count(local:getHit($docsSmall, '2005'))) (: uncomment the line below to change getHit result :) (: let $a := trace("res 2 : " || count(local:getHit($docsSmall, '2005'))) :) return '' Result is : "res 1 : 1" After uncommenting the second call, result is: "res 1 : 2" "res 2 : 2" The same with this more simple xquery: declare function local:getHit($documents, $word) { (# db:enforceindex #) { $documents//*[text() contains text {$word}] } }; let $docs := collection() let $docsSmall := $docs[1] let $a := trace("res 1 : " || count(local:getHit($docsSmall, '2005'))) return '' Result is : "res 1 : 2" ("res 1 : 1" expected) 2 documents are populating this database : <book category="COOKING"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> and <book category="CHILDREN"> <title lang="en">Harry Potter</title> <author>J K.

running several updating queries from a single query?
by Graydon Saunders 10 Jun '25

10 Jun '25

Hello! So if I have a number of updating queries, what's the best way to write a query that will run all of them in some fixed order? (I am doing this from the GUI.) All the individual updating queries do what they're expected to do and it works if I run them in sequence from the GUI, query one, query two, and so on. If I try to chain them together: xs:anyURI('updating-query-1.xq') => xquery:eval-update(), xs:anyURI('updating-query-2.xq') => xquery:eval-update() Seems to work OK for the first two or three and then to start having issues (in the sense that the updates don't appear to happen to the target) if I chain four or five together. (The updating queries get the db name to update from a common xquery module.) It also looks inelegant, like there ought to be a better way. Anyone got any suggestions? Or is this not a sensible thing to be attempting? Thanks! Graydon

Optimizing query that reads nodes from two databases
by Matt Dziuban 04 Jun '25

04 Jun '25

Hi all, I'm working on a query that reads from two databases -- OriginalDB and UpdateDB. The structure of each database is the same: <data> <item id="1">...</item> <item id="2">...</item> ... </data> OriginalDB has 2,305,570 items and UpdateDB has 307,019. The query gets all distinct item ids from the two databases, then gets the item with a matching id (if there is one) from each database, and returns the id and both nodes in a JSON object. Here's the query: let $originalDB := db:get('OriginalDB')/data/item let $updateDB := db:get('UpdateDB')/data/item for $id in distinct-values(($originalDB/@id, $updateDB/@id)) let $original := $originalDB[@id = $id] let $update := $updateDB[@id = $id] return json:serialize(map { 'id': xs:long($id), 'original': $original, 'update': $update }, map { 'indent': 'no' }) In its current state this query is very slow -- it's returned only 35 JSON objects in ~30 minutes. How can I go about optimizing it to best take advantage of each database's indices? Thanks in advance, Matt

BaseX 12.0 is tripping on the XSLT transformation that outputs text, not XML
by ykhabins＠bellsouth.net 03 Jun '25

03 Jun '25

Hello, It seems that BaseX 12.0 beta 2686758, and later, is tripping on the XSLT transformation that outputs text, not XML. I am using SaxonHE12-5J. Even the following XQuery setting is not helping. declare option output:method 'text'; IMHO, BaseX should read the output:method attribute from an XSLT and handle it properly. method? = "xml" | "html" | "xhtml" | "text" | "json" | "adaptive" | eqname https://qt4cg.org/specifications/xslt-40/Overview.html#id-xsl-output-declar… Below is an easy repro.

Questions about xslt:transform-text and xslt:transform-report
by Lizzi, Vincent 02 Jun '25

02 Jun '25

Hello BaseX team, I typically use the xslt:transform-text function to apply an XSLT stylesheet and obtain the result that is serialized by Saxon according to the xsl:output instructions in the stylesheet. The xslt:transform-report has the advantage of providing access to messages created by xsl:message instructions. I have a few questions about these functions: Is there a way to use the xsl:transform-report function to obtain messages and the serialized result (instead of document nodes) that is currently returned by xslt:transform-text? Is there a way to provide a base URI in the options of xsl:transform-text (or xsl:transform-report or xsl:transform)? If the input to the transformation is on disk then the base URI is set automatically, however if the input is held in memory then the base URI is not set so it could be helpful to be able to provide a base uri to the transformer as an option. The documentation doesn't mention these capabilities so I'm guessing that these things are not currently possible. Thank you, Vincent ______________________________________________ Vincent M.

difference of type of $schema for different validation functions?
by Martin Honnen 02 Jun '25

02 Jun '25

Why is the function https://docs.basex.org/main/Validation_Functions#validate:xsd documented as taking the schema as item()? while the function https://docs.basex.org/main/Validation_Functions#validate:xsd-report documents the schema as xs:string? ? Is that a documentation error or quirk or are these two functions taking different types of arguments for the schema?

BaseX GUI create dialog differences from db:create()?
by Graydon Saunders 25 May '25

25 May '25

Hello and happy Friday -- I'm using BaseX 11.9. I have a processing chain of queries that takes some XHTML documents and loads them into a DB. Another query reads that DB, merges the documents, and writes the merged version to disk. From the disk copy, I create a DB of the merged content, and run another query to update that. (Changing the image references.) I then I use another query to write the updated DB back out to disk. If I create the DB of the merged content with the BaseX GUI "new database" dialog, everything works. If I create the DB of the merged content using db:create('mergedChapters', file:children($mergedDir), (), map { 'ftindex': true(), 'casesens': true(), 'createfilter': '*.html' }) I get a database and I can use db:get() to query it; for example, db:get('mergedChapters')//*:img from a GUI editor window gives me the expected result. (I also get the expected "you can't do that" error if I make the DB the context DB and attempt to run the "load the merged version" query again.) When I try to run the "update the image references" query (also from a GUI editor window, and also using db:get() to access the DB) after creating the mergedChapters dB from XQuery, it does NOT work. So far as I can tell, it doesn't alter the DB at all. I'm very sure I'm using the same database name; it's been copied out of the update-the-image-references query. I don't see an option to make the db changeable in the db:create() options. Any suggestions? Thanks! Graydon

preventing tranforming empty element with begin- and endtag to self-closing-tag
by Rob Stapper 23 May '25

23 May '25

Hi Christian, Basex seems to transform 'begin-/endtagged' element with empty content to a single self-closing-tagged element: <div></div> is transformed to: </div> This gives problems in my client application. Both in Chrome, Edge and Firefox transforms Javascript's "insertAdjacentHTML": <div> <div/> <div>tekst</div> <div>tekst</div> </div> to: <div> <div> <div>tekst</div> <div>tekst</div> </div> </div> This is not what is intended. I guess for void-elements this transformation is ok but result in problems like this in case of container-elements. Is it possible in Basex to suppress this transformation? mvgr. Rob Stapper

Fwd: Re: functionParameterTyping issue
by Rob Stapper 20 May '25

20 May '25

Hi Christian, Good news, I hope. The problem with the dynamic typecasting is not as much a typecasting-issue but an issue with recognizing derived functions. The problem is that derived functions are treated as functioncalls where it shouldn't. I can remenber that once there was an issue with the parity of derived functions. It is something like that. attached some demos: [referentialDemo.xq] shows that dynamic and strict typing works within version-11.9 [buggyDemo.xq] shows that dynamic and strict typing fails in case of derived functions. [workingDemo,xq] show the workaround. Thought you would like to know what the issue is.

If there is a (hidden) dependency in the semantics in your code that $p will always be a map if $n is "a", it is something the complete cannot »guess«.

11.9 doc() not working with DOCTYPE declaration
by Graydon Saunders 15 May '25

15 May '25

Hello -- I'm on linux, using 11.9 and using 20:59 graydon % java -version openjdk version "21.0.7" 2025-04-15 OpenJDK Runtime Environment (Red_Hat-21.0.7.0.6-1) (build 21.0.7+6) OpenJDK 64-Bit Server VM (Red_Hat-21.0.7.0.6-1) (build 21.0.7+6, mixed mode, sharing) If I use the basexgui "Create DB" dialog and the internal parser, I can load the whole folder without error; I get the expected DB and the named entities in the content have been resolved. (These are effectively HTML 4 entity names, so that's not completely guaranteeing that the DTD in the DOCTYPE is being found and parsed somewhere.) If I use the doc() function with an absolute file system path to one of the same files that loaded into the DB just fine, I get an error. I get the same error if I try to switch off the internal parser and set a catalog. It's at least several files in the folder that loads fine as a DB. All of this works fine with 11.8; whatever changed changed in 11.9. The error is: Could not execute XQUERY doc('/home/graydon/GeneralCode/git/cpc-conversion/Chapter/BU4372-14A.xml'): Improper use?

xqj-api library
by Lyn Elisa Goltz 14 May '25

Hi all, BaseX is an excellent tool, and we are interested in integrating its API into our open-source project. Our project is licensed under the AGPL-3.0, and we want to ensure license compatibility with all the libraries we use. Unfortunately, BaseX depends on the xqj-api library, for which neither a license nor source code appears to be available. The main concern, therefore, is the unclear provenance of this dependency. Could you please provide the license information or the source code for this library? Best regards, Lyn -- l a t / l o n GmbH Im Ellig 1 53343 Wachtberg, Germany phone ++49 +228 24 333 784 http://www.lat-lon.de http://www.deegree.org lat/lon gesellschaft für raumbezogene informationssysteme mbH Registergericht: Amtsgericht Bonn, HRB 13042 Geschäftsführer: Jens Fitzke und Torsten Friebe
