Bash command
by meumapple 19 Nov '15

19 Nov '15

Hi all, I am using proc:system for a bash command but I cannot run it. It looks like opennlp postagger model.bin < file.txt. I suspect that the problem is the less-than sign, which is converted into < Is there any way to keep the less-than sign and pass it to the bash properly? Thanks. Joseph

How to improve performance of join query
by Chuck Bearden 18 Nov '15

18 Nov '15

Hi all, I'm joining elements from two sets of documents in a single database. There are many elements (six figures) in each set. The query doesn't finish after several minutes. My suspicion is that the indices aren't being used, except to limit the fingerprint 'content' elements to those with "Person" as the value of 'contentFamily'. Perhaps my data and query demand some form of optimization that hasn't been implemented yet, but perhaps there is something I could do to fix the query. I'm using BaseX 8.3.0. The query: ------------------------- xquery version "3.0"; declare namespace fingerprint="http://atira.dk/schemas/pure4/wsdl/template/fingerprint/current"; declare namespace concept="http://atira.dk/schemas/pure4/wsdl/template/concept/current"; declare namespace core="http://atira.dk/schemas/pure4/model/core/current"; declare namespace xsi="http://www.w3.org/2001/XMLSchema-instance"; declare namespace fincur="http://atira.dk/schemas/pure4/model/template/fingerprint/current"; declare namespace concur="http://atira.dk/schemas/pure4/model/template/concept/current"; declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization"; declare option output:method "csv"; declare option output:csv "header=yes, separator=comma"; let $coll := collection('pure_20151109') let $concept_contents := $coll/concept:GetConceptResponse/core:result/core:content let $fingerprint_contents := $coll/fingerprint:GetFingerprintResponse/core:result/core:content for $fin_con in $fingerprint_contents[fincur:contentFamily/text()="Person"] /fincur:rankedConcepts/fincur:rankedConcept let $concept_uuid := $fin_con/fincur:conceptUuid let $rank := $fin_con/fincur:rank let $weighted_rank := $fin_con/fincur:weightedRank let $person_uuid := $fin_con/ancestor::core:content[1]/@uuid let $concept_name := $concept_contents[@uuid=$concept_uuid]/concur:name/core:localizedString return <csv> <record> <person_uuid>{data($person_uuid)}</person_uuid> <concept_uuid>{$concept_uuid/text()}</concept_uuid> <rank>{$rank/text()}</rank> <weighted_rank>{$weighted_rank/text()}</weighted_rank> <concept_name>{$concept_name/text()}</concept_name> </record> </csv> ------------------------- The query info from the query, which I stopped after 3 minutes: ------------------------- Error: Interrupted.

zip:update-entries - unexpected results
by Hondros, Constantine (ELS-AMS) 18 Nov '15

18 Nov '15

Hi all, I'm attempting to create a modified copy a zipfile using zip:update-entries, but my output is a zip structure with zero-byte files. Am I missing a step? I've followed the example in: http://docs.basex.org/wiki/ZIP_Module#zip:update-entries Code snippet as follows: declare function util:clean-zip($zip as xs:string, $out as xs:string) { copy $doc := zip:entries($zip) modify delete node $doc//zip:entry[ends-with(lower-case(@name), '.pdf')] return zip:update-entries($doc, $out) }; Thanks for any pointers ;-) C. ________________________________ Elsevier B.V.

sending variables to xquery module via client api (python)
by Cholfin, Bryan 17 Nov '15

17 Nov '15

Hi- Hoping someone can help me with this. I'm trying to write a python script that calls an xquery module in the database. It seems to be pretty easy to use a line such as: session.execute("run gettext.xqm") and get back the response I want. What I want to do is pass a bound variable to the module. The client api has a provision to bind a variable to a query object, but I'm not making a query object. I'm simply executing the stored query. I don't find anything in the documentation to suggest that a variable can be added to the run command this way.

Restxq
by meumapple 16 Nov '15

16 Nov '15

Hi All, I am using restxq. I wrote a function which takes one variable (this should be a chunk of text, not a single word). The output is xml. I can have the function work if I pass the content of the variable with curl -X POST --data "variable=my text is long" http://address How can I get the same result of the curl command with an xquery function? More in general, is this a good way to write a function in restxq when the variable is not a single word but the content of a file? (I am not even sure if a file can be passed as such in restxq) Thanks, Joseph

Treating SQL Results
by Ana Victória Ladeira 16 Nov '15

16 Nov '15

Good morning. I have an XML file of the following format: <?xml version="1.0" encoding="UTF-8"?> <resultsets> <resultset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <row> <column name="TITULO">A Adequação de Sistemas Baseados em Casos no Sequenciamento Inteligente de Ações</column> <column name="NOMECOMPLETO">José Pacheco de Almeida Prado</column> </row> <row> <column name="TITULO">Sistemas Distribuídos Inteligentes</column> <column name="NOMECOMPLETO">José Pacheco de Almeida Prado</column> </row> <row> <column name="TITULO">Uma Arquitetura para Planejamento Inteligente</column> <column name="NOMECOMPLETO">José Pacheco de Almeida Prado</column> </row> <row> <column name="TITULO">Navegação de robôs móveis com Lógica Paracpmsistente Anotada e método de Campos Potenciais</column> <column name="NOMECOMPLETO">José Pacheco de Almeida Prado</column> </row> <row> <column name="TITULO">Adaptation in a Traffic Control System</column> <column name="NOMECOMPLETO">José Pacheco de Almeida Prado</column> </row> ... The file contains titles for articles and their authors.. I was asked to develop a query that returns the author's name followed by the titles of all of its articles, so the result would be something like this: <Author1>:<Article1>, <Article2>, <Article3>... <Author2>:<Article1>, <Article2>... ... Any ideas on how can I do it? Thank you in advance.

Typo in docs?
by Marco Lettere 13 Nov '15

13 Nov '15

Hi all, Just one question. The documentation page related to the json module states: *Signatures* |*json:serialize*($input as node()) as xs:string| |*json:serialize*($input as node(), $options as map(xs:string, xs:string)) as xs:string| *Summary* Serializes the node specified by|$input|as JSON, and returns the result as|xs:string|instance. The node is expected to conform to the output created by thejson:parse() <http://docs.basex.org/wiki/JSON_Module#json:parse>function. All other items will be serialized as specified for thejson output method <http://docs.basex.org/wiki/XQuery_3.1#JSON_Serialization>of the official specification. Items can also be serialized as JSON if theSerialization Parameter <http://docs.basex.org/wiki/Serialization>|method|is set to|json|. The|$options|argument can be used to control the way the input is serialized. But I think the signature should be for item()? for the first parameter (since it allows also for maps) isn't it? In effect inspect:function(json:serialize#2) returns <function name="json:serialize" uri="http://basex.org/modules/json"> <argument type="item()" occurrence="?"/> <argument type="item()" occurrence="?"/> <return type="xs:string"/> </function> If it's confirmed I could proceed with fixing it. Regards, Marco.
