Multi-valued values in maps - sequences vs arrays
by Bridger Dyson-Smith 03 Aug '22

03 Aug '22

Hi all - I would appreciate some help understanding how I might go about having a multi-valued array as the value of a map key, or if this is even possible; e.g. map{ "key": [1,2,3,4,5] } I've tried various combinations of array:flatten and array:join, but things always wind up in a sequence. (Aside: this isn't a real problem, but I'm trying to force myself to get more comfortable working with arrays and maps and this seemed like a great exercise... :) My mistake!). E.g. map:merge( (1 to 5) ! map {'key': array:flatten(array { . }) }, map{"duplicates":"combine"} ), (: returns map{"key":(1,2,3,4,5)} :) map:merge( (1 to 5) ! map {'key': array:join(array {.}) }, map{"duplicates":"combine"} ) (: returns map{"key":([1],[2],[3],[4],[5])} :) Are sequences the result because a map is a function item? Thanks for any clarity you can provide! Best, Bridger

BaseX 10 • The Double-Digit Summer Edition
by Christian Grün 03 Aug '22

03 Aug '22

Dear all, It’s been around 15 years ago when the first Open-Source version of BaseX was released. Thanks to the continuous support of all of you, we are thrilled today to announce the first double-digit version of our XML framework: https://basex.org/ BaseX 10 assists you with your everyday data challenges with some great new features: STORAGE • Beside XML Documents and Binary Data, you can use the new »XQuery Values« resource type to store arbitrary items and sequences in databases. • General data (registered users, scheduled services, and key-value stores) can now be backed up as well. • Mixed-content developers will be delighted: Whitespaces are now preserved by default. XQUERY • Database locking has been improved by splitting up XQuery compilation into a static and dynamic step. • A new Store Module allows you to organize values in a persistent main-memory key-value store. • You can store and retrieve XQuery values with db:put-value and db:get-value. • When serializing XML, indentation is now turned off by default. GENERAL • BaseX 10 requires Java 11 to run. • The GUI comes with improved HiDPI support, new icons and improved consistency. • All HTTP requests are now based on the new Java HTTP client. • Catalog support is now universal and based on either the new XML Catalog API or Norman Walsh’s excellent XML Resolver. • The default ports for web applications were changed from 8984/8985 to 8080/8081. • The default admin password was removed to improve security. • Results of the REST API are now wrapped in the default REST namespace. We have taken the version jump as an opportunity to rename various existing functions and commands. The database storage has not changed: Databases created with BaseX 10 are backward compatible and can still be opened with BaseX 9. Visit our documentation for more details, and information on how to upgrade your existing applications: https://docs.basex.org/wiki/BaseX_10 Have fun! Your BaseX Team

RESTXQ use cases for POST, PUT and DELETE
by Stefan Ziegler 03 Aug '22

03 Aug '22

Hi I'm wondering what are real world use cases for POST, PUT and DELETE requests? Are they used for updating / importing / deleting data into e.g. an xml database? Or is it common to use it e.g. for uploading an xml file and transform it into a pdf (with xsl-fo)? regards Stefan

BaseX 10.0 and Java 11 requirement
by ykhabins＠bellsouth.net 01 Aug '22

01 Aug '22

Hello, Congrats on the BaseX 10.0 release. I tried to install BaseX 10.0 on my two computers. First computer (Windows 10 OS) - I installed Java JDK jdk-18_windows-x64_bin.exe - Installation of the BaseX 10.0 went without any problem. BaseX GUI is working without any problems. Second computer (Windows 10 OS) is giving me a grief. - I installed the same Java JDK jdk-18_windows-x64_bin.exe - Installation of the BaseX 10.0 is producing the following error message: " Please install Java 11 or higher before executing the installer." My troubleshooting steps: (1) At the command prompt, c:\>java --version, shows the following java 18.0.2 2022-07-19 Java(TM) SE Runtime Environment (build 18.0.2+9-61) Java HotSpot(TM) 64-Bit Server VM (build 18.0.2+9-61, mixed mode, sharing) (2) I added to the System Environment Variable Path, the following: c:\Program Files\Java\jdk-18.0.2\bin\ So far, no progress. The same " Please install Java 11 or higher before executing the installer." error message. Pleas advise. Regards, Yitzhak Khabinsky

fn:apply with an updating function
by Hans-Juergen Rennau 28 Jul '22

28 Jul '22

Dear BaseX people, I encounter a problem with standard function fn:apply(), applied to an updating function. declare %updating function f:apply-dbPut($db as xs:string, $input as item(), $path as xs:string) { let $fn := function-lookup(QName('http://basex.org/modules/db', 'put'), 3) let $args := [$db, $input, $path] return apply($fn, $args)}; Message:[XUST0002] Function body must be updating. Therer seems to be a checking looking for an updating function, and apply() cannot, of course, be classified as such. Do I make a mistake, or is it a limitation, or a bug? Thank you for checking, kind regards -Hans-Jürgen

BaseX YAML Parser?
by Eliot Kimber 26 Jul '22

26 Jul '22

I found myself needing to operate on some YAML documents and tried to find an XQuery YAML parser and did not find one, at least not one of sufficient completeness. It seems like kind of an obvious missing thing in the XQuery world so just curious if I missed something? I don’t have time myself to write one—it can’t be that hard but it’s not that critical of a need for me. I ended up using the Python PyYAML library, which let me quickly convert YAML to JSON, which then I could of course process just fine with XQuery. Thanks, E. _____________________________________________ Eliot Kimber Sr Staff Content Engineer O: 512 554 9368 M: 512 554 9368 servicenow.com<https://www.servicenow.com> LinkedIn<https://www.linkedin.com/company/servicenow> | Twitter<https://twitter.com/servicenow> | YouTube<https://www.youtube.com/user/servicenowinc> | Facebook<https://www.facebook.com/servicenow>

Available Integration with Apache POI for Excel Generation?
by Eliot Kimber 25 Jul '22

25 Jul '22

I tried searching for “BaseX Excel generation” but it didn’t get me farther than a reference to the CSV module, which of course I am familiar with. I need to add the ability to generate non-trivial Excel spreadsheets, which I know how to do using the Apache POI library, but being lazy I was hoping somebody had already done it in a shareable form. So my question: Does anyone have or know of a shareable integration of Apache POI with BaseX for generating Excel spreadsheets or some other Excel-generation solution that is not just downloading CSV files? Thanks, E. _____________________________________________ Eliot Kimber Sr Staff Content Engineer O: 512 554 9368 M: 512 554 9368 servicenow.com<https://www.servicenow.com> LinkedIn<https://www.linkedin.com/company/servicenow> | Twitter<https://twitter.com/servicenow> | YouTube<https://www.youtube.com/user/servicenowinc> | Facebook<https://www.facebook.com/servicenow>

What Would "Server is running or permission was denied." Indicate?
by Eliot Kimber 18 Jul '22

18 Jul '22

One my RESTXQ pages constructs an HTML report that takes a few seconds to construct. The page works fine in my local dev environment but when I deploy the code on my production server the process fails after constructing the report markup with the log messages: Server is running or permission was denied. Server is running or permission was denied. Server is running or permission was denied. That is, the message is emitted three times in a row with about 50ms between and the page generation fails (page never appears in the browser). Any idea what condition this might indicate and how I might track it down? It must be something I’m doing in my code but I can’t find any obvious logic bugs so wondering what kind of thing I might look for. Thanks, Eliot _____________________________________________ Eliot Kimber Sr Staff Content Engineer O: 512 554 9368 M: 512 554 9368 servicenow.com<https://www.servicenow.com> LinkedIn<https://www.linkedin.com/company/servicenow> | Twitter<https://twitter.com/servicenow> | YouTube<https://www.youtube.com/user/servicenowinc> | Facebook<https://www.facebook.com/servicenow>
