Results from ft:extract()
by Lars Johnsen 02 Dec '13

02 Dec '13

Hello all When using ft:extract() on nodes, it seems to clip into the match itself too often. Is it possible to have ft:extract() leave as much before the match as after? For example, here are two results for "spise lunsj" (= eat lunch (language is Norwegian)) the first is as it should be, while the second have half of the matched string clipped . The result is obtained first as a set of hits using fulltext search [text() contains text {$terms} all], then each hit is processed through ft:extract($hit, $terms): ... gjerne komme for å spise lunsj med meg på Harrods. Da skal jeg servere hjortetestikler fra eiendommen min i Skottland. Vi trenger nemlig alle store... ... de franske VM-spillerne hjem til Paris. Der ble de mottatt av fans både på Charles de Gaulle-flyplassen og da de ankom Elysee-palasset for å spise ... Regards, Lars G Johnsen National Library of Norway

by Erol Akarsu 02 Dec '13

I would like to generate CDATA of one xmk construct like this. This does not calculate $1,$f2 and $f3 and insert their serialized version into features tag Can we do this in xquery? let $allfs := <record> <name>{$name}</name> <features> <![CDATA[ <h3>Features:</h3> <br/> <ul> <li>{$f1}</li> <li>{$f2}</li> <li>{$f3}</li> </ul> ]]> </features> </record> Erol Akarsu

XQUERY command and PHP
by Tsvetanka Georgieva-Trifonova 02 Dec '13

02 Dec '13

Hi Basex, My question is about the command XQUERY [query]. Does it work with any XQuery queries or only with XPath? I tried the following: <?php include("BaseXClient.php"); // create session $session = new Session("localhost", 1984, "admin", "admin"); $session->execute("open myfirstdatabase"); echo $session->execute("xquery for $n in //country[name = 'Switzerland'] return $n") ; // close session $session->close(); ?> This example causes the error: [XPST0003] Incomplete 'window' expression.' But the following example: <?php include("BaseXClient.php"); // create session $session = new Session("localhost", 1984, "admin", "admin"); $session->execute("open myfirstdatabase"); echo $session->execute("xquery //country[name = 'Switzerland']") ; // close session $session->close(); ?> is executed without error. The difference between the two examples is that one uses XQuery and another - XPath expression. Please, tell me whether the command XQUERY can be used with any XQuery queries and how exactly? Thanks & regards, Tsvetanka

Full text queries ok :)
by Ingarao Maud 02 Dec '13

Hello everybody Thanks to your help Christian, our full text queries yet work fine. I still don't understand exactly what the problem was and why we got 500 internal errors. Maybe a too heavy query and thus a memory problem ? Anyway now with this kind of writing, the queries are completed : declare function desanti:display-tags($collection, $dataType, $mode){ let $label := if($dataType = "subject") then "concepts" else "personnes" return <div class="{ $mode }"> <h6>{ $label }</h6> <span>{ for $term in $collection group by $term order by $term collation "?lang=fr" let $occurrences := count( ft:search('Desanti', $term)/..[local-name() = $dataType][ parent::*:controlaccess/ parent::*:c/ ancestor::*:dsc/ parent::*:archdesc/ parent::*:ead/ parent::document-node() ] ) return if($mode = "cloud") then ( <span><a style="font-size:{ $occurrences idiv 10 + 1 }em;padding:{ $occurrences idiv 10 }px;" title="{ $occurrences }" href="/restxq/desanti/{$label}/{$term}">{$term}</a></span> ) else ( <span class="{ $occurrences }"><a href="/restxq/desanti/{$label}/{$term}">{ $term }</a> ({ $occurrences }) </span> ) }</span> </div> }; Thanks a lot !!!

Perf issue
by jean-marc Mercier 01 Dec '13

01 Dec '13

Hello, I am encountering a performance issue with BaseX interpreter, illustrated by the snippet code above. This code first creates a sequence of 100000 integers, taking more than a minute with my environment. Then it creates a BaseX map of 100000 integers, taking 0.1 sec. This issue seems to be due to a poor performance of the operator () (see function local:id below). This could be an issue for the BaseX interpreter, or a problem with my environment, but might be also a XQUERY 3.0 "leak". Have you any idea ? cheers Jean-Marc declare function local:id($el) as function() as item()* {function(){ $el }}; declare function local:new() {local:id(())}; declare function local:new($map,$item) {local:id(($map(),$item))}; let $nb := 100000 return let $testid := fn:fold-left(for $i in 1 to $nb return $i,local:new(), function($map,$entry){local:new( $map,$entry )}) let $basexmap := fn:fold-left(for $i in 1 to $nb return map:entry($i,$i),map:entry(0,0), function($entry,$map){map:new( ($map,$entry) )}) return (fn:count(prof:time( $testid )),fn:count(prof:time( $basexmap )))
