Hi all, hi Christian, is it possible to combine wildcards and thesaurus in a fulltext-search, for example: contains text "nachricht.*" using wildcards using thesaurus at "thesaurus.xml" Best regards, Günter

Automatically generating test cases. Hidden feature?
by Marc van Grootel 13 Jan '16

13 Jan '16

Hi, Been a long time since posting. Work is very busy recently. Luckily for me a lot of it involves XQuery ;-) I am elaborating some examples [1] that show off the use of my Origami [2] library. The most promising ones I will turn in to blog posts or a wiki at some point. Recently I've been reading a bit about generative testing (or property-based testing) and libraries like Haskell's QuickCheck. I hope to be able to show that we can use such techniques in combination with RelaxNG and the concepts that Eric van der Vlist describes in Examplotron [3] to mutate XML instances guided by a schema that I can then turn into automatically generated tests. It's still early days and time is limited but I did stumble onto something interesting that I wanted to share here. If you already use similar techniques I would be very interested to hear about it. I was contemplating if it was possible to create anonymous unit test functions that I can invoke with generated test input. So, a bit to my amazement, the following works: let $equals := %unit:test function($a,$b) { unit:assert-equals($a,$b, 'Not equal') } return $equals(4,3) This function raises the unit:UNIT0001 exception with the message "Item 1: 3 expected, 4 returned". Cool! So if this is possible can we also catch a failure and turn it into data? let $equals := %unit:test function($a,$b) { unit:assert-equals($a,$b, 'Not equal') } return try { $equals(4,3) } catch * { <error> <code>{ $err:code }</code> <description>{ $err:description }</description> <value>{ $err:value }</value> <module>{ $err:module }</module> <line-number>{ $err:line-number }</line-number> <column-number>{ $err:column-number }</column-number> </error> } This too works and produces an XML fragment recording the failure. Very cool! <error> <code>unit:UNIT0001</code> <description>Item 1: 3 expected, 4 returned.</description> <value>Not equal</value> <module>.../origami-examples/check/demo.xq</module> <line-number>23</line-number> <column-number>24</column-number> </error> I am not sure if this a hidden or an intentional feature of the BaseX unit module. I sure hope that it doesn't go away in future releases as I intend to leverage this in an alternative testing module. BaseX, the gift that keeps on giving, thanks to all that make it possible. --Marc [1] https://github.com/xokomola/origami-examples [2] https://github.com/xokomola/origami [3] http://examplotron.org/

minor issue in the project-view of BaseX-GUI with error marking
by Rob Stapper 13 Jan '16

13 Jan '16

Hi, I found that when a directory contains both a program- and a module-file with the same name but with different extensions ( .xq and .xqm) both file are marked as erroneous in the project-view if only one file, on my case the module-file, is indeed erroneous and the other file is ok. Regards, Rob Stapper PS. It is my unittest-directory that contains both program- and module-files.

We have JSON that has string/text values which are XML. Is there a way o have the XML as sub-elements value and not be encoded/escaped string? Wray Johnson

XQUF 3.0, MIXUPDATES
by Hans-Juergen Rennau 12 Jan '16

12 Jan '16

Dear BaseX team, version 3.0 of the XQuery Update Facility (XQUF) allows expressions to perform an updating operation *and* return a value (e.g. [1]). Presently, BaseX supports probably only version 1.0 of the XQUF, so the mixing of update and value creates an error - and option MIXUPDATES equal "true" does not change this.: Query:=============================== declare option db:mixupdates 'true'; 100, insert node <elem/> into * ================================>Stopped at C:/projects/act/updateQuery.xq, 5/1: [XUST0001] List expression: all expressions must be updating or return an empty sequence. In my opinion, the possibility to mix updating and value construction is very important, as otherwise it is impossible to develop versatile tools which may, dependent on call parameters, either return a result or perform an update. So my Q U E S T I O N is - are there already plans to support XQUF 3.0 - or as a first step the mixing of update and value - soon? Would be phantastic! Cheers,Hans-Jürgen [1] http://www.w3.org/TR/xquery-update-30/#id-comma-expr"The operand expressions of the comma expression are evaluated,and the XDMinstances and pending update lists returned areconcatenated in operand order. Pending update lists are concatenatedby the upd:mergeUpdates operation."

XML Commands
by E. Wray Johnson 12 Jan '16

12 Jan '16

How do you execute XML commands from the BaseX GUI? Why can't multiple XML commands be executed from the BaseXClient.java? How can database options (e.g. autooptimize) be changed from the GUI without opening the database and locking it?

Fulltext Stemming
by kleist 12 Jan '16

12 Jan '16

Hi all, with query options: contains text "grün" all using diacritics sensitive using stemming using language 'German' I'll get: "grüne", "grüner", "Grüns" etc. But I also get "Gruß", "Grüße", "grüßen" or something like "Gruner" (Eigenname) Does the stemming have problems with german umlaute and "ß"? with query options: contains text "grün" all using stemming using language 'German' same results, but less. Why is that? The indexes of the database are the following: Indexes Up-to-date: true TEXTINDEX: true ATTRINDEX: true FTINDEX: true TEXTINCLUDE: ATTRINCLUDE: FTINCLUDE: LANGUAGE: German STEMMING: true CASESENS: true DIACRITICS: true STOPWORDS: UPDINDEX: false AUTOOPTIMIZE: false MAXCATS: 100 MAXLEN: 96 INDEXSPLITSIZE: 0 FTINDEXSPLITSIZE: 0 Optimized Query is the following: Optimized Query: let $hits_137 := ft:mark((db:open-pre("kleist-searchindex",147544), ...)/(((descendant::tei:s union descendant::tei:l)))[descendant::text() contains text "grün" all using diacritics sensitive using stemming using language 'German']) return element div { (element p { ("grün") }, element p { (count($hits_137)) }, element ul { (for $hit_139 in $hits_137 return element li { ($hit_139/descendant-or-self::node()/ancestor::tei:TEI/descendant-or-self::node()/tei:classCode[position() = 1]/string(), $hit_139) }) }) } Best, Günter
