XML Prague: Little Update
by Christian Grün 01 Dec '15

01 Dec '15

Hi all, We are currently assembling the talks for our XML Prague User Meeting. You will soon find more information on our Lanyrd conference page [1]. For example, it’s not settled yet if the meeting will take place in the morning or afternoon (afternoon would be our favorite). We are still looking for speakers; please let us know if you are interested! All the best, Christian [1] http://lanyrd.com/2016/basex/

Running BaseX under Tomcat on a commercial Java hosting provider
by C. M. Sperberg-McQueen 01 Dec '15

01 Dec '15

In case there are other users of XQuery who are looking for a way to get an XQuery engine on the Web but are not sure how to go about it, I have described my adventures setting up one approach (running BaseX 7.9 under Tomcat 6 on a commercial Java hosting provider) in a blog post today, hoping that it might enable someone else to do it with less trouble and confusion than I had: http://cmsmcq.com/mib/?p=1368 When time allows, I expect to upgrade my Tomcat to Tomcat 7 so that I can install a current BaseX; I'll update the post then with information for BaseX 8.*. if those who understand Java development and deployment better than I do (or wish to do) find errors in the exposition or simpler ways to get things set up, I would be glad to have them pointed out. I'd also be interested in speculations as to why setting the default user in web.xml seems not to have worked, but at this point I doubt that it's worth significant effort to solve that problem. -- **************************************************************** * C.

RESTXQ : existing annotation for response headers ?
by Etanchaud Fabrice 30 Nov '15

30 Nov '15

Dear all, When I want to set response headers (for example to force a "save as..."), I currently have to write a specific response before the response body : <rest:response> <http:response> <http:header name="Content-Type" value="text/comma-separated-values; charset=utf-8"/> <http:header name="Content-Disposition" value="attachment; filename={concat($base, '_Parthenay.csv')}"/> </http:response> </rest:response> Is there an annotation to set header values directly in the function declaration ? Best regards, Fabrice

Location of users.xml
by Tom Rauchenwald 27 Nov '15

27 Nov '15

Hi, is it possible to override the expected location of users.xml? >From the wiki (http://docs.basex.org/wiki/User_Management) > The permission file has been moved from the home directory to the > database directory. It was renamed from .basexperm to users.xml We're using the war distribution, and would prefer to either specify the location of users.xml via a parameter or have it reside in the war. Is this currently possible? Thanks, -tom

db:create, namespaces not stripped when input is variable?
by Hondros, Constantine (ELS-AMS) 27 Nov '15

27 Nov '15

Hello all, Any particular reason behind this observed behaviour? (Basex 8.3). .............................................................. [1] .............................................................. declare variable $test := <test xmlns:ce="http://www.elsevier.com/xml/ani/common" xmlns="http://www.elsevier.com/xml/ani/ani"> <ce:initials>M.S.</ce:initials> </test>; db:create('test', $test, 'blah', map {'stripns':true()}) .............................................................. [2] .............................................................. db:open('test')/* .............................................................. [3] .............................................................. <test xmlns="http://www.elsevier.com/xml/ani/ani" xmlns:ce="http://www.elsevier.com/xml/ani/common"> <ce:initials>M.S.</ce:initials> </test> I would have expected the namespaces to be shredded ...

Cant add raw files explicitly or text index ms office docs
by E. Wray Johnson 26 Nov '15

26 Nov '15

Here is what I want to do: For a given folder and all its subfolders on my physical dive, mirror its contents including the contents of archives, parsing xml, json,html, text, etc. using their respective parser skipping invalids, and adding all other files as raw. I want archive files (*.zip, *.doxc) to be added as raw, however I want the text inside archive files like docx (ms-word) to be indexed and any files in the archives files that match a filter to be indexed. Note: It would be nice if there was a single db:add method that allowed me to specify a map of filters to parsers with options, where all files that do not match a filter (or are invalid) will be optionally added as raw.

file:read-binary performance
by Jérôme Chauveau 25 Nov '15

25 Nov '15

Hi, My restxq app is very slow to deliver raw files (css, images, js). For example, the restxq method takes around 600ms to load a png file in my browser when it takes only 2ms in a "direct" or "static" way. --------------------------------------- declare %rest:path("/editions/static/{$project}/{$file=.+}") function max.file:file( $project as xs:string, $file as xs:string ) as item()+ { let $path := file:parent(file:base-dir()) || 'editions/' || $project || '/ui/' || $file return ( web:response-header(map { 'media-type': web:content-type($path) }), file:read-binary($path) ) }; --------------------------------------- Why such a difference? How can I improve it? I am using BaseX 8.3 (war version). Regards, Jérôme -- Jérôme Chauveau - CERTIC-DSI - Campus I Université de Caen Normandie

Assigning incrementing number to 100ks of elements
by Chuck Bearden 24 Nov '15

24 Nov '15

BaseX 8.3.1, installed on Linux today from zip archive. I have about 137,000 target elements, each having an average of 550 descendant elements, and each taking about 45k of space on disk. The target elements each have an @uuid value, and I'd like to extract each @uuid value and assign it a unique number from an incrementing sequence of integers. I'd like to be able to start the sequence at an arbitrary value. I tried a recursive function I borrowed and modified from a StackOverflow post: declare function local:loop($seq, $count) { if(empty($seq)) then () else let $prod := $seq[1], $count := $count + 1 return ( <result> <id>{$count}</id> <uuid>{data($prod)}</uuid> </result>, local:loop(tail($seq), $count) ) }; and calling it like so: return <results>{ local:loop($pubs, 0) }</results> where $prod is a sequence of all the @uuid attributes (not the values, and not the whole elements). My query fails with the error: [bxerr:BASX0005] Stack Overflow: Try tail recursion? I'm using -Xmx6g and -Xss4m as flags for Java in the basexgui script. Is there some way to get BaseX to use tail recursion? Or is there another approach to doing what I want? Many thanks, Chuck

issue with stack trace in query-info window
by Rob Stapper 24 Nov '15

24 Nov '15

Hi Christian, I found that in case of a runtime error the links in the stack trace in the Query info window to the different locations in the program don't work anymore. I use of course the latest snapshot: BaseX 8.4 beta 3b6f6e0 Regards, Rob --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. https://www.avast.com/antivirus
