recursively used variables
by Rob Stapper 12 Aug '24

12 Aug '24

Hi, The code[1] below and send as attachment generates a error message: “Static variable depends on itself: $Q{http://www.w3.org/2005/xquery-local-functions}test”. I use these variables to refer to my private functions in my modules so I can easyly refer to them in a inheritance situation. It’s not a big problem for me but I was wondering if the error-triggering is justified or that it should work. [1]=========================================== declare variable $local:test := local:test#1 ; declare %private function local:test( $i) { if ( $i > 0) then $local:test( $i - 1) } ; $local:test( 10) =========================================== Kind regards, Rob Stapper Sent from Mail for Windows 10 -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Autocomplete with RESTXQ
by Imsieke, Gerrit, le-tex 21 Jul '21

21 Jul '21

Hi List, Can anyone recommend a lightweight vanilla Javascript autocomplete library that can easily be used together with BaseX RESTXQ? Maybe even a readily cloneable/modifiable example? I don’t have a preference for a server response format. The RESTXQ service may be configured to return XML, JSON, or HTML No CORS restrictions need to be considered, the query host is the same that delivers the HTML pages. Gerrit

Package for system integration
by karlo＠fastmail.com 20 Jun '21

20 Jun '21

I have packaged basex in a way that I believe will be easier for integration with package managers. https://klarinet.kos.ovh/fossil/basex-root-install/uv/basex-9.4.3.tar.gz >From the root of that archive, you can build and install like this. make make install # as root The above will install to the prefix /usr/local. You can set a different prefix. Here is an example. make clean make PREFIX=/usr make PREFIX=/usr install # as root A secondary benefit of this package is the removal of the bash dependency. Could a package like this be distributed officially? If that is agreeable, I am happy to try incorporating this into the present build system. Here is a utility for preparing the package. It depends on sh and other Unix-like utilities. https://klarinet.kos.ovh/fossil/basex-root-install/dir?ci=tip With distinguished salutations, Kralj Karlo

thesaurus URILiteral vs node
by Liam R. E. Quin 01 Jun '21

01 Jun '21

What would be involved in extending BaseX's full text to allow a thesaurus to be supplied as a node instead of a URI? I want to construct one on the fly, and using file:write() seems excessive.

insert MS SQL server bigint from BaseX via sql:execute-prepared
by Martin Honnen 31 May '21

31 May '21

I am trying to use BaseX to enter data from its XML db into an MS SQL server database, according to https://docs.microsoft.com/en-us/sql/connect/jdbc/using-basic-data-types?vi… the MS SQL server column type bigint is mapped to long in Java. However, when I try <sql:parameter type="long">{$id}</sql:parameter> with BaseX and sql:execute-prepared, I get an error saying [sql:error] An SQL exception occurred: unsupported type: long The BaseX documentation https://docs.basex.org/wiki/SQL_Module#sql:execute-prepared indeed only lists attribute type { "int" | "string" | "boolean" | "date" | "double" | "float" | "short" | "time" | "timestamp" | "sqlxml" } as the possible types. Am I out of luck trying to use BaseX that way for that datatype? Using <sql:parameter type="int">{$id}</sql:parameter> the sql doesn't succeed.

BaseX with Apache
by Tim Thompson 27 May '21

27 May '21

With apologies for the not-strictly-BaseX question--but I'm running BaseX through a reverse proxy with Apache (and Let's Encrypt), and I can't figure out how to disable directory listing for the BaseX webapp/static directory. I've tried editing the apache2 conf files in the standard ways. Hoping someone here has a quick solution to share. Thanks in advance, Tim -- Tim A.

BaseX 9.5.3
by Christian Grün 27 May '21

27 May '21

Dear all, A new BaseX patch release is available. It comes with minor bug fixes and little enhancements: • RESTXQ responses now come with a Server-Timing HTTP header (motivated by Reece) • A context file can be specified via the Bindings Dialog of the XQuery editor (motivated by Hans-Jürgen) • The current HTTP context will now be propagated if jobs:eval is called • The DBA CodeMirror and Jetty libraries have been updated Find the new version on our web site: https://basex.org/ Have fun, Christian

Running XQuery Update via apply Ant task
by Zimmel, Daniel 26 May '21

26 May '21

Hi, is there anyone using BaseX in an Apache Ant scenario? I have the following target for XQuery Updating some files (no database access), but I am too dumb to make an apply task that reads every file in a fileset. Usually you place the <srcfile/> where you need it to be in your external command, but unfortunately the BaseX command-line syntax won't allow this to be easily placed: the filename is supposed to follow directly suffixed to "-i" where I cannot use an element, of course. <target name="xquery_update_default"> <echo level="info" message="XQuery Update (Default): ${param.xquery-update-uri}"></echo> <apply executable="java" > <arg value="-cp"/> <arg value="BaseX95.jar"/> <arg value="org.basex.BaseX"/> <arg line="-u"/> <arg line="-w"/> <arg line="-c'set exporter omit-xml-declaration=no,indent=no'"/> <arg line="-b'path=${param.folder}'"/> <arg line="-i${dummy.xml}"/> <srcfile/> <fileset dir="../${dir.xquery}" includes="${param.xquery-update-uri}"/> </apply> </target> As a workaround, I set a dummy.xml for input and bind the current folder as a parameter and in my Query I can use file:list() which then is updating all files in the directory, but this makes the Query dependent on the parameter, and updates are obviously not written back unless all files have been processed in memory. I would prefer to have a standalone query operating only on the current document-uri (so I can better reuse it elsewhere). Can someone give me a hint if it is possible in plain Ant to apply a CCL-BaseX to any file in a given fileset? Other than that, BaseX performs well as a file processor (if you ignore the time related to file handling). Thanks, Daniel

BUG node comparison
by ydyxeb＠post.cz 26 May '21

26 May '21

Dear BaseX, according to github instructions I’m sending a bug report via email: Using BaseX 9.5.1, cmd-line “basex.bat -i datafile.xml queryfile.xq” leads to no result at all. I’m convinced there should be result equivalent to the one of the online xquery tester (https://www.videlibri.de/cgi-bin/xidelcgi) For a modified query using string comparison based on fn:path(), BaseX gives the expected result. %%% query begin %%% let $rootElement := /child::* for $x in //Section[parent::* != $rootElement] return fn:path($x) %%% query end %%% %%% data begin %%% <root> <Section id="should not be reported 1" /> <Section id="should not be reported 2"> <Section id="should be reported 1"/> <a> <Section id="should be reported 2"/> </a> </Section> <a> <Section id="should be reported 3"/> </a> </root> %%% data end %%% %%% modified query begin %%% let $rootElementPath := fn:path(/child::*) for $x in //Section[fn:path(parent::*) != $rootElementPath] return fn:path($x) %%% query end %%% Kind regards Jan Červák

CSV and automatic encoding detection
by Kristian Kankainen 24 May '21

24 May '21

Hi folks, I am aware that with the HTML module you can let it guess a file's encoding by itself by providing it in binary format: > If the input encoding is unknown, the data to be processed can be passed on in its binary representation. The HTML parser will automatically try to detect the correct encoding: > > Query > html:parse(fetch:binary("https://en.wikipedia.org")) But is there a way to guess encoding of CSV files? So far I have tried with the fetch and CSV module with no results. I have a huge bunch of CSV files and they are all in different encodings. Maybe it is possible to pipe the content of the fetch:binary to a system command for guessing the encoding, and use this to read in the csv? Best regards, Kristian Kankainen
