Database Query in RESTXQ function
by Alexander Krasnogolowy 29 Mar '23

29 Mar '23

Hi, given the following RESTXQ function: declare %rest:path("/myrest/{$db}") %rest:GET %output:method("xhtml") %output:omit-xml-declaration("no") %output:doctype-public("-//W3C//DTD XHTML 1.0 Transitional//EN") %output:doctype-system("http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd") function page:html($db as xs:string) { <html xmlns="http://www.w3.org/1999/xhtml"> <body> Database creation date: {db:info("NB")/databaseproperties/timestamp/text()}<br/> </body> </html> }; The website returns "Database creation date: " (without a timestamp) If I put that into a function: declare function page:getDBTimestamp($db as xs:string) { db:info($db)/databaseproperties/timestamp/text() }; and call it in the page: <body> Database creation date: {page:getDBTimestamp($db)}<br/> </body> then I can see the timestamp. Can somebody explain to my why it makes a difference and why I cannot query the database directly from the RESTXQ function? Alex

collection('i_do_not_exist')/users/user[@name=()] is () even if i_do_not_exist does not exit
by Omar Siam 23 Mar '23

23 Mar '23

Hi, Either I found an interesting new XQuery feature or a bug: collection('i_do_not_exist')/some/path[@attr=()] retruns the empty sequence whereas collection('i_do_not_exist')/some/path throws an error err:FODC0002 so does collection('i_do_not_exist')/some/path[@attr="i_am_an_attr"] Am I missing something?

Issue with the Java 11 XML Catalog API and xsl:import/xsl:include
by Imsieke, Gerrit, le-tex 22 Mar '23

22 Mar '23

Hi, We experience an issue with the new catalog resolver when importing or including XSLT from another, possibly already catalog-resolved, XSLT file. If you unzip attached catalog_test.zip and set the catalog location by a pragma around xsl.xq or by set BASEX_JVM="-Dorg.basex.catalog=../catalog_test/xmlcatalog/catalog.xml" prior to invoking basexgui.bat or bin\basex.bat ..\catalog_test\xsl.xq, you will get an exception Improper use? Potential bug? Your feedback is welcome: Contact: basex-talk(a)mailman.uni-konstanz.de Version: BaseX 10.4 Java: Eclipse Adoptium, 17.0.4.1 OS: Windows 11, amd64 Stack Trace: javax.xml.catalog.CatalogException: JAXP09040002: No match found for href 'other.xsl' and base 'file:/C:/Users/gerrit/Dev/catalog_test/xsl/imported.xsl'. … If I use Norm’s resolver by putting xmlresolver-5.1.1.jar and xmlresolver-5.1.1-data.jar into lib/custom, I get the expected result <result status="ok"><doc>other.xsl was imported!</doc></result> Therefore the issue isn’t urgent. We just use Norm’s resolver. Should I file an issue on Github?

erreur librairies Saxon 11 avac BaseX 10.4
by Maud Ingarao (IHRIM - ENS de Lyon) 20 Mar '23

20 Mar '23

Bonjour à tous et toutes, En passant de BaseX 10.3 à BaseX 10.4, nous avons l'erreur ci-dessous. Quelque chose ne va pas avec les librairies XSLT Saxon.... Si nous mettons les anciennes librairies Saxon 9 à la place des librairies Saxon 11, l'erreur disparaît. Nous aimerions pouvoir utiliser les librairies les plus récentes. Merci de vos conseils :-) Amitiés, Maud HTTP ERROR 500 javax.xml.transform.TransformerFactoryConfigurationError: Provider net.sf.saxon.TransformerFactoryImpl could not be instantiated:

Progress bar (again)
by Zimmel, Daniel 16 Mar '23

16 Mar '23

Hey, I have a task that may take longer to execute (several minutes), so I felt I got to have a fancy progress bar on the command line to entertain me. No progress bar though, found this in the archives: https://mailman.uni-konstanz.de/pipermail/basex-talk/2020-November/015845.h… So this is the closest I got (running BaseX from an Ant task): xquery_update_db: [echo] XQuery Update (Database) wird ausgeführt: xquery/basex.reduce.xquery [apply] EXPORTER: omit-xml-declaration=no [apply] Database 'DEBUGX' was opened in 113.62 ms. [apply] "FORTSCHRITT: 0%" [apply] "FORTSCHRITT: *****5%" [apply] "FORTSCHRITT: **********10%" [apply] "FORTSCHRITT: ***************15%" [apply] "FORTSCHRITT: ********************20%" [apply] "FORTSCHRITT: *************************25%" While I am happy enough with this (it is quite accurate and I like the dramatically mounting effect), can anyone say what might be needed to implement this as a module?

"class file versions" discrepancy
by Murray, Gregory 15 Mar '23

15 Mar '23

Hello, I’m new to BaseX. I’m on a Mac with an Apple M1 chip, running macOS 12.6.3. I downloaded the ZIP distribution of BaseX. When I open BaseX.jar I get an error message saying to check the console. When I run basexgui at the command line, I get this error: Exception in thread "main" java.lang.UnsupportedClassVersionError: org/basex/BaseXGUI has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 I updated Java to the latest version, according to the download page at java.com and according to the Update tab in the Java control panel in System Preferences. Running java -version returns this: java version "1.8.0_361" Java(TM) SE Runtime Environment (build 1.8.0_361-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.361-b09, mixed mode) However, I am still getting the same error when running basexgui. Is there a trick or workaround for this? Thanks, Greg

Formatting attributes as an indented list?
by Patrick Durusau 07 Mar '23

07 Mar '23

Greetings! I've been tasked with using BaseX to produce: ***** <wg class="cl" rule="S-IO" cltype="VerbElided"> <wg rule="NpaNp" role="s"> <wg type="group" appositioncontainer="true" rule="Np-Appos"> <w ref="PHM 1:1!1" after=" " class="noun" gbiType="proper" xml:id="n57001001001" lemma="Παῦλος" normalized="Παῦλος" strong="3972" number="singular" gender="masculine" case="nominative" gloss="Paul" domain="093001" ln="93.294a" morph="N-NSM" unicode="Παῦλος">Παῦλος</w> ***** The indenting is easy enough and I can even make it deeper if required but is there a command for serialization that will properly format the attributes? My personal suspicion is that inserting \n when each attribute is serialized (and not on the last one) is the easier route but I promised to investigate the command line. Have I overlooked something in the very fine manual? Hope everyone is having a great week!

Dear all, I'm trying to setup a new instance of BaseX 10 in order to start migrating some applications of ours. Anyway I'm unable to set the admin password. Followin https://docs.basex.org/wiki/BaseX_10#Migrating_Applications, I'm currently trying with [1] and [2] which both ask me to enter a new password. But afterwards I keep getting [3].... and I'm unable to access dba too. I cannot understand what I'm doing wrongly ... Any help? Thanks!

Labas, Christian, Dar neturiu Lietuviska font tai rasisiu Angliskai. What I am looking for is documentation on how to perform simple UNION's and/or JOIN's. I have two DB's with data. DB1 has a small sample data set. DB2 is a master data repository. I need to find DB1 data that does not exist in the master repository. Sound simple enough, but I need examples with the proper syntax. Thanks in advance for your time and help. Linkejimai, KAS Kestutis J Katinas
