rest:response and status 400/404
by Marco Lettere 16 Apr '14

16 Apr '14

I've the following simplified RESTXQ code snippet that I use with basex 7.8. declare %rest:path("/exists") %rest:HEAD %rest:form-param("message","{$message}") function page:exist( $message as xs:string) { try{ if ($message = 'yes') then () else error(xs:QName("err:ERR"), "Message wasn't yes!") } catch * { <rest:response> <http:response status="404" reason="{$err:description}"> <http:header name="DBG" value="{'message was '|| $message}"/> </http:response> </rest:response> } }; This is always returning HTTP status 404 with reason "No function found that matches the request". This happens only for the 400 status code. Any other status code I use to set behaves as expected including 404 itself. Any hints? Thank you. Regards, Marco.

Updating expressions using REST?
by Fredrik Hedberg 14 Apr '14

14 Apr '14

Hi, I'm having problems with updating expressions using REST. Non-updating queries execute fine without errors but when I use updating expressions the REST service returns a 400 (bad request) error. For instance: the following body of a POST request <run xmlns='http://basex.org/rest'><text>insertDummy.xq</text></run> with code in file insertDummy.xq: xquery version '3.0'; insert node <structure>nada</structure> into collection("component")/structures sent to: http://admin:admin@localhost:8984/rest/component/ returns a "(400) Bad request" error while if I substitute the code in file insertDummy.xq for a non updating expression such as: xquery version '3.0'; let $r := collection("component")/structures return $r it works fine! I suspected this was a result of user rights so I added the admin credentials to the http path. No change, problem persists. Also, I de-installed the program, made sure all files were gone, and then re-installed the (win PC) program again to wipe any weird settings I may have changed. Still no luck... The above code did work on a previous installation (I beleive I was using 7.7.1). Any help would be highly appriciated. Many thanks, Fredrik Hedberg

CSV multiple character separators
by Hondros, Constantine (ELS-AMS) 14 Apr '14

14 Apr '14

A small request for your growing backlog ... it would be wonderful if your CSV import wizard was able to accept multiple-character separators. We have oodles of data in which the double at-sign '@@' signifies a field separator. No ... don't ask me why! Keep up the good work! C. ________________________________ Elsevier B.V.

Re: [basex-talk] how to insert attribute?
by Arto Viitanen 14 Apr '14

14 Apr '14

http://docs.basex.org/wiki/XQuery_Update mentions insert attribute. So how can I insert attribute? $ cat x.xq copy $c := <entry> <title>Transform expression example</title> <author>BaseX Team</author> </entry> modify ( replace value of node $c/author with 'BaseX', replace value of node $c/title with concat('Copy of: ', $c/title), insert node <author>Joey</author> into $c, insert attribute Z {'B'} into $c/title, ) return $c $ basex x.xq Stopped at /tmp/x.xq, 10/10: [XPST0003] Expecting ')', found 'a'. Attribute is node, so insert node attribute Z {'B'} into $c/title. On replace: replace value of node $another/@Y with 'C'. -- Arto Viitanen

multiple modules, one target namespace
by Maximilian Gärber 10 Apr '14

10 Apr '14

Hi, as far as I understand http://www.w3.org/TR/xquery-30/#id-module-handling-multiple-same it should be possible to have more than one module (-> file) with the same target namespace inside the "repo" folder This seems not possible at the moment because the .xqm file has to have a name according to the target namespace I would like to use function-lookup to access functions that might be added at runtime (new file, but the target namespace would be pre-defined) Regards, Max

XQuery comments in Return clause?
by Hondros, Constantine (ELS-AMS) 10 Apr '14

10 Apr '14

Hi all, I can't tell if this is a bug or not. I commented out a line in my Return clause so that I could test performance. To my surprise, the comment was interpreted as part of the literal response, and the expression within the commented line was evaluated. If this is expected behaviour, is there a workaround? return <dup> <pii>{ $val }</pii> (: {/results/dataset/item[pii = $val]/dbpath} :) </dup> ---------------------- Result: ---------------------- <dup> <pii>0022-0728(92)80265-6</pii> (: <dbpath>SCODAT00000000001/15726657/v336i1-2/0022072892802657/main.xml</dbpath> <dbpath>SCODAT00000000002/15726657/v336i1-2/0022072892802656/main.xml</dbpath> :) </dup> <dup> ________________________________ Elsevier B.V.

Efficient query for duplicates
by Hondros, Constantine (ELS-AMS) 09 Apr '14

09 Apr '14

I'm running out of memory (1.5 GB allocated) when querying for duplicate node values over a fairly flat XML database of approximately 450 MB. Can anyone suggest a more memory-efficient approach to framing this query than iterating over distinct-values as I do below? I'm hoping that there are some Basex tips and tricks to help out here. for $val in distinct-values(/dataset/item/pii) let $cnt := count(/dataset/item/pii[. = $val]) return if ($cnt > 1) then <duplicate>{$val}</duplicate> else null Thanks in advance, Constantine ________________________________ Elsevier B.V.

Bulk Processing of JSON
by Shaun Flynn 09 Apr '14

09 Apr '14

Hello there, I am working in a project to work with train schedules. Sadly, the data is given to me as a series of JSON objects which need to be read in line by line. Is there a way of batch processing JSON, or do I have to submit line by line? Shaun
