A minimal command line I am able to run (it is Windows Powershell) is e.g. C:\Users\marti\.jdks\temurin-17.0.15\bin\java.exe -cp '.\BaseX.jar;.\lib\custom\saxon-he-12.8.jar' org.basex.BaseX "xslt:transform('sample1.xml', 'sheet1.xsl')" I hope that gets you up and running.

command line xsl transformation
by Rory Campbell-Lange 23 Jul '25

23 Jul '25

Hi -- beginner here. I've installed basex via apt on Debian. ii basex 10.5-1 all XML database and XPath/XQuery processor I've successfully made and interrogated a database and made a few basic xquery commands from the command line. I'm hoping to use basex for xsl transformations from the command line so that I can work rapidly on iterating towards the transformation I'm trying to achieve. Specifically, I'm aiming to transform an XML document using an XSL document to produce an HTML document. I've tried the following, plus other variants: basex -W -i input.xml -o out.html transform.xsl However the resulting file at out.html is simply the transform.xsl file. I'd be grateful for advice. Many thanks, Rory

BaseX version, installation recommendations
by Rory Campbell-Lange 23 Jul '25

23 Jul '25

Dear List I may be working soon on a commercial server supporting XQuery 3.1+ with its own proprietary extensions, and XSLT 2.0. Would basex 12 be the best match for these protocol versions (except of the proprietary components, of course)? I'm most interesting in working in an iterative fashion on the command line, as I'm used to doing with vim and psql (the postgresql interactive terminal). If basex 12 is recommended, any pointers to getting this running on Debian would be gratefully received. Unfortunately Debian testing (https://packages.debian.org/sid/basex) still points to basex 10.5. I'm not familiar with Java installation requirements. Thank you for the project, which looks excellent. Many thanks, Rory

csv:doc(), csv:parse() functions are not respecting the 'field-delimiter': 'tab' parameter
by Yitzhak Khabinsky 21 Jul '25

21 Jul '25

Hello, I am using BaseX 12.0 It seems that the csv:doc(), csv:parse() functions are not respecting the 'field-delimiter': 'tab' parameter. It emits the following error: [csv:parse] The value of 'field-delimiter' is not a single character: 'tab'. Though the old style parameter is working: 'separator': 'tab' It is documented here: https://docs.basex.org/main/CSV_Functions#options Repro is below. Failing XQuery =============== declare variable $csv_file as xs:string external := 'c:\path\to\input.txt'; declare variable $xml_file as xs:string external := 'c:\path\to\output.xml'; let $input_options := { 'header': false(), 'trim-whitespace': true(), 'field-delimiter': 'tab' } let $output_options := {'indent': 'yes', 'method': 'xml', 'encoding': 'UTF-8'} return csv:doc($csv_file, $input_options) -> file:write($xml_file, ., $output_options) Working XQuery =============== declare variable $csv_file as xs:string external := 'c:\path\to\input.txt'; declare variable $xml_file as xs:string external := 'c:\path\to\output.xml'; let $input_options := { 'header': false(), 'trim-whitespace': true(), 'separator': 'tab' } let $output_options := {'indent': 'yes', 'method': 'xml', 'encoding': 'UTF-8'} return csv:doc($csv_file, $input_options) -> file:write($xml_file, ., $output_options) Regards, Yitzhak Khabinsky

Restore from Backup: Should it work to restore backup from system A on system B?
by Eliot Kimber 10 Jul '25

10 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 ?

Property 'http://www.oracle.com/xml/jaxp/properties/entityExpansionLimit' is not recognized
by ykhabins＠bellsouth.net 04 Jul '25

04 Jul '25

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
