Hi, I have modified BaseX_JVM for GUI to 3072M and Java Runtime parameter -Xmx3072m. BaseX GUI will not open if the BaseX_JVM value is more than 1400. Then I have to go to bin and edit the file to 1400 or less so it will open again. Please advise how this can be fixed? Thanks Mohamed

BaseX XSLT fails after returning first result
by Furst, Thomas 21 May '20

21 May '20

I have a large XML file stored in BaseX that I need to split up into smaller, modular documents. I have created an XSL file to do so: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0"> <xsl:output indent="yes" encoding="UTF-8"/> <xsl:param name="schema"/> <xsl:param name="model"/> <xsl:param name="sysDiff"/> <xsl:param name="sys"/> <xsl:param name="subsys"/> <xsl:param name="subsubsys"/> <xsl:param name="assy"/> <xsl:param name="disassy"/> <xsl:param name="disassyv"/> <xsl:param name="info"/> <xsl:param name="infov"/> <xsl:param name="itemloc"/> <xsl:param name="tname"/> <xsl:param name="iname"/> <xsl:param name="outputDir"/> <xsl:template match="/"> <xsl:result-document href="{concat($outputDir, '/DMC-',$model,'-',$sysDiff,'-',$sys,'-',$subsys,$subsubsys,'-',$assy,'-',$disassy,$disassyv,'-',$info,$infov,'-',$itemloc,'.xml')}" method="xml"> <dmodule> <identAndStatusSection> <dmAddress> <dmIdent> <dmCode modelIdentCode="{$model}" systemDiffCode="{$sysDiff}"> <xsl:attribute name="systemCode" select="$sys"/> <xsl:attribute name="subSystemCode" select="$subsys"/> <xsl:attribute name="subSubSystemCode" select="$subsubsys"/> <xsl:attribute name="assyCode" select="$assy"/> <xsl:attribute name="disassyCode" select="$disassy"/> <xsl:attribute name="disassyCodeVariant" select="$disassyv"/> <xsl:attribute name="infoCode" select="$info"/> <xsl:attribute name="infoCodeVariant" select="$infov"/> <xsl:attribute name="itemLocationCode" select="$itemloc"/> </dmCode> <language languageIsoCode="en" countryIsoCode="US"/> <issueInfo issueNumber="000" inWork="01"/> </dmIdent> </dmAddress> </identAndStatusSection> </dmodule> </xsl:result-document> </xsl:template> </xsl:stylesheet> My issue is that when using the xslt:transform() function in BaseX it only returns (creates) the first document. This is the XQuery I have for this: let $style := doc('file:///C:/base.xsl') for $d in doc('file:///C:/Users/tfurst/Documents/Book1-test.xml')//title for $newD in //*[title] where $newD/title/@id eq $d/@id let $schema := $d/schemaName let $model := $d/modelic let $sdc := $d/sdc let $sys := $d/systemCode let $subsys := $d/subsys let $subsubsys := $d/subsubsys let $assy := $d/assy let $disassy := $d/disassy let $disassyv := $d/disassyv let $info := $d/infoCode let $infov := $d/infov let $itemloc := $d/itemloc let $tname := $d/tname let $iname := $d/iname return xslt:transform($newD,$style, map {"outputDir":"file:///G:/LMA-Conv/Flight/test-conv-out", "model":$model, "sysDiff":$sdc, "sys":$sys, "subsys":$subsys, "subsubsys":$subsubsys, "assy":$assy, "disassy":$disassy, "disassyv":$disassyv, "info":$info, "infov":$infov, "itemloc":$itemloc, "tname":$tname, "iname":$iname}) The document named Book1-test.xml is essentially a map of existing IDs of elements to new output file names. After it creates the first XML output file BaseX returns ERROR [FODC0002] "" (Line 1): Premature end of file. When I looked up the error code in the BaseX documentation this error is defined as "The specified document resource cannot be retrieved. ". Is there some limitation to the use of the xslt:transform function in a loop? I am not understanding why it was able to retrieved the first time, but not after that. I have tried to move the XSL to different file locations, no luck. Am I missing something ridiculously obvious here? This XSL stylesheet is a very simplified version of what it will ultimately become, I wanted to get the process down before fully developing the XSL.

Help composing an http:request with POST
by Bridger Dyson-Smith 20 May '20

20 May '20

Hi all - I'm trying to use BaseX to POST an image to a digital asset management system (i.e. I'm not using RESTXQ, etc, just using BaseX to compose and send the request). The request: http:send-request( <http:request method='POST' username='{$user}' password='{$pass}' auth-method='Basic' send-authorization='true'> <http:multipart media-type='multipart/form-data'> <http:body media-type='image/tiff'/> </http:multipart> </http:request>, ' http://localhost:8080/fedora/objects/tdh:2/datastreams/OBJ?versionable=true… ', file:read-binary('/path/to/my/image.tif') ) I'm a hapless caveman when it comes to http, and so when the binary content gets POSTed, the mime-type becomes something like 'multipart/form-data;boundary=1BEF0A57BE110FD467A'. I'm clearly missing something in the http:request but... I don't know what. Any suggestions? It seems like I need some training wheels here, but I'm not sure which ones. :) Thank you, in advance, for your time and trouble. Best, Bridger

distinct-values and type coercion
by Marco Lettere 19 May '20

19 May '20

Dear all, after installing Basex 9.3.3 one application of ours started failing in a particular functionality. We tracked it down to the following example code: let $in := <json type="object"> <source type="object"> <reference>Object/20383920-5bb1-4397-8b51-b752863acddf</reference> </source> </json> let $s as xs:string* := distinct-values($in/source/reference/string()) return $s This code now returns the following error: [XPTY0004] Cannot treat xs:untypedAtomic* as xs:string*: distinct-values($in_0/element(source)/element(reference)). Whereas before it was automatically casting to xs:string now it seems that the type coercion in the let clause is too restrictive. This happens only with the distinct-values applied by the way. Is it correct now or was it before? For the moment we solved by removing the type enforcement in the let clause. Thank you for the clarification. Regards, Marco.

Full-text index: searches for common words in another node. Does it take a lot of time?
by Sebastian Guerrero 19 May '20

19 May '20

Hi everybody. I'm here again with my doubts. Thank you for your patience. ^^ I have a database of trademarks with a full-text index for two nodes: **:mark-identification,*:party-name*. [1] Where "*mark-identification*" contains the name of the trademark, and " *party-name*" contains the name of the owner of the trademark. I use the full-text index in order to search trademarks by its name, for example: *for $results in //case-file[case-file-header/mark-identification/text() contains text {'basex'}]* *return $results//mark-identification* returns all trademarks with "*basex*" on its name. It works like a thunderlight: 15ms to get 3 records among 2,134,434,598 nodes. Really a dream. [2] But, for example, if I change the searched text from "*basex*" by a common word in "*party-name*", for example, "*corporation*" ( has 1096187x occurrences on the full-text index as showed in [1], it's a very common word in owners of trademarks ): *for $results in //case-file[case-file-header/mark-identification/text() contains text {'corporation'}]* *return $results//mark-identification* It takes a long time to get 6,715 records: 62,000ms [3] If I search for "*live*" ( a common word for trademarks name, but not for owners names ) I get 5,875 records in 2,773 ms, which has not a relationship with the 62,000ms to get the 6k records for "*corporation*". [4] So... - Is this an expected behaviour? - Is there a way to specify which "section" of the full-text index should be used to perform the search? ( I don't know... maybe something similar to "*using stemming*" but "*using index 'mark-identification'*" ) Please apologize me if I'm asking by something not-logical, Best regards, Sebastian [1] https://imgur.com/uLla1Xt [2] https://imgur.com/Fkcvv2O [3] https://imgur.com/Hk71CNe [4] https://imgur.com/P72k574

Same query returns different amount of records
by Sebastian Guerrero 18 May '20

18 May '20

Hi everyone! it's me again. Here is my doubt: If I execute this query: * (# db:enforceindex #) { for $db in ('US00','US01','US02') for $tmUS in db:open($db)/trademark-applications-daily/application-information/file-segments/action-keys/case-file where $tmUS/case-file-header/mark-identification/text() contains text { 'apple' } return $tmUS/case-file-header/mark-identification/text() }* I get 4k results in 139ms from three databases of 90GB and 13M of records. It works like a charm. [01] But, if I include that query into a *for* and then into a *switch* ( I tried with *if-then-else* too ), the same query returns only 11 results in 107ms [02]: *declare namespace gb="http://www.ipo.gov.uk/schemas/tm <http://www.ipo.gov.uk/schemas/tm>";* *let $text := "apple"* *let $registries := ('US')* *for $registry in $registries* *return * * switch ($registry)* * case "US"* * return * * (# db:enforceindex #) { * * for $db in ('US00','US01','US02')* * for $tmUS in db:open($db)/trademark-applications-daily/application-information/file-segments/action-keys/case-file* * where $tmUS/case-file-header/mark-identification/text() contains text { $text }* * return $tmUS/case-file-header/mark-identification/text()* * }* * case "GB"* * return* * (# db:enforceindex #) {* * for $tmGB in db:open('GB')/gb:MarkLicenceeExportList/gb:TradeMark* * where $tmGB/gb:WordMarkSpecification/gb:MarkVerbalElementText/text() contains text { $text }* * return $tmGB/gb:WordMarkSpecification/gb:MarkVerbalElementText/text()* * }* * default return "Unknown registry code"* I noticed that removing the case option "GB" ( even if it's not evaluated ), it works fine and returns the 4k records [03]: *declare namespace gb="http://www.ipo.gov.uk/schemas/tm <http://www.ipo.gov.uk/schemas/tm>";* *let $text := "apple"* *let $registries := ('US')* *for $registry in $registries* *return * * switch ($registry)* * case "US"* * return * * (# db:enforceindex #) { * * for $db in ('US00','US01','US02')* * for $tmUS in db:open($db)/trademark-applications-daily/application-information/file-segments/action-keys/case-file* * where $tmUS/case-file-header/mark-identification/text() contains text { $text }* * return $tmUS/case-file-header/mark-identification/text()* * }* * default return "Unknown registry code"* What I'm missing here? is this the right behaviour?

14 May '20

Hello BaseX team, Using Resful API, I'm trying to make POST method update BaseX database, I want to insert an xml node to an existing document calastone.xml in calastone database , but the node contains '<', you replied to a previous email that I should use fn:parse-xml to make this happen without error. I tried using the function fn:parse-xml, I had success with using it in BaseX GUI like this: let $message := fn:parse-xml('<Id>CTN55</Id>') return insert nodes $message as last into doc("calastone/calastone.xml") But when I tried to do the same with POST method from my application with using this xquery: string xquery = "<query><text>let $message:= fn:parse-xml('<Id>CTN58</Id>')" + "return insert nodes $message as last into doc(\"calastone/calastone.xml\")</text>" + "<variable name = 'message' value = fn:parse-xml('<Id>CTN58</Id>'))/></query>"; I get the error: "" (Line 1): Element type "variable" must be followed by either attribute specifications, ">" or "/>" Can you help on how to do this insertion? Thanks. P Respectons ensemble l'environnement. N'imprimez ce message que si n?cessaire. Let's respect the environment together. Only print this message if necessary.

Directory and files are neither a file or a directory on Basex 9.3.2 when read from Docker volume
by France Baril 14 May '20

14 May '20

Hi, Here is my issue. I create a new container with Basex 9.3.2 I add a volume ContentDBs under my basex directory ContentDBs has 2 directories and 1 files I run this code from an xqm: let $src-dir-items := file:list('ContentDBs') let $debug := file:append('debug-a.xml', 'count: ' || count($src-dir-items) || '
') let $dirs := for $i in $src-dir-items (: Bug items are neither a dir or a file !? Because volume from docker? :) let $debug := file:append('debug-a.xml', 'item: ' || $i || ' is dir: ' || file:is-dir($i) || '
') let $debug := file:append('debug-a.xml', 'item: ' || $i || ' is file: ' || file:is-file($i) || '
') return $i In the debug file, I get. - The count for items is 3 - For all items, is-dir and is-file are false. I get a similar error if I try to db:create from one of the folders, it seems to recognize that I have a folder, but it chokes on subfolders with: Resource 'js/' does not exist. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

I am confused how to specify multiple possible reponses in RestXQ with %rest:produces
by Omar Siam 12 May '20

12 May '20

Hi, Today someone on the exist-open mailing list pointed out how they interpret %rest:produces: If your function produces more types of responses you specify all mime types just the same as with %rest:consumes: %rest:poroduces("application/xml", "application/json", ...) That is as a list of possible reponses all in one annotation. The BaseX docs at https://docs.basex.org/wiki/RESTXQ#Content_Negotiation however are ambigous about this I think. There is an example there with just two %rest:produces annotations on two lines with only one mime type (and a qs value). I think that lead me to belief that to specify multiple possible responses of different mime types you repeat %rest:produces. Rereading the section these two example annotations could also ilustrate the use of %rest:produces in two different functions. Can you please clarify this if possible? Best regards Omar Siam

GUI "create db" file patterns are not sticky
by Graydon Saunders 12 May '20

12 May '20

This is a very small feature request. Everything else about the Create Database GUI is sticky -- when changed it stays changed -- EXCEPT the file patterns. Would it be possible to make the file patterns sticky as well? I often need to create a new database repeatedly since I'm using XQuery to test output from XSLT processes during development. Remembering to add all the file patterns is not excessively burdensome but I would like to not have to do it. Thanks! Graydon

Query optimizer bug with nested for? - java.lang.NullPointerException at Path.index(Path.java:673)
by Sebastian Guerrero 11 May '20

11 May '20

Hi everybody! Maybe it's a newbie issue, but I would like your comments. I'm writing a RESTXQ method to search among a couple of databases. ( >100 databases ) Some databases are split into a couple of parts due to the number of nodes. For example US: it's separated into US00, US01 and US02. So, my problem is: if I replace "*for $usPart in ('US00')*" by "*for $usPart in ('US00','US01',''US02)*" in *QUERY [A]*, I get this error: *Improper use? Potential bug?

repeatedly full-text marking the same text node
by Graydon Saunders 11 May '20

11 May '20

Hello -- Is there some way to iterate full-text matches to mark up in the node every found member of a sequence of phrases? I have a use case where I have a long list of phrases which may appear in the content set; if they do appear in the content set, these should be marked. The order of the list is significant; the longest phrases should be marked first. The idea would be to iterate through the list, marking up the node with any matches. However, so far as I can tell, full text only works directly on a database node. If I try to pass the node in a function, I get "No database node" errors from attempting full-text operations. (Making a copy of the DB with a full text index, applying the changes, updating the indexes, and continuing seems possible but also inherently inefficient.) Is there a straightforward way to do this that I'm missing? Thanks! Graydon

Stack overflow with random-number-generator
by Joe Wicentowski 11 May '20

11 May '20

Hi all, I encountered a stack overflow error with the following code, which is designed to return as many random numbers as the user requests. BaseX's error suggested, "Try tail recursion?" I think I am already using tail recursion. Changing the $n variable from 1407 to 1406 or lower avoids the error. Any number 1407 or higher triggers the error. Thank you for any hints! Joe ``` xquery version "3.1"; declare function local:get-random-numbers($how-many as xs:integer, $generator as map(*)) { if ($how-many ge 1) then ( $generator?number, local:get-random-numbers($how-many - 1, $generator?next()) ) else () }; declare function local:get-random-numbers($how-many as xs:integer) { local:get-random-numbers($how-many, random-number-generator()) }; let $n := 1407 return local:get-random-numbers($n) => count() ```

Performance loss between version 9.2.4 and 9.3.2 when executing specific xQuery
by BIRKNER Michael 11 May '20

11 May '20

Hi, I am observing a performance loss between BaseX versions 9.2.4 (which I was using so far) and 9.3.2 (to which I updated recently) when executing an xQuery like this: --- (: Open 2 databases and get all <record>s :) let $recsFromDb1 := db:open('db1')/record let $recsFromDb2 := db:open('db2')/record (: Get distinct IDs of all records in db1 :) let $idsFromRecsInDb1 := distinct-values($recsFromDb1/exampletag[@exampleattr='id']) (: Iterate over the distinct IDs of db1 and return the records from db2 with the same ID :) for $id in $idsFromRecsInDb1 let $recFromDb2WithSameId := $recsFromDb2[exampletag[@exampleattr='id']=$id] return $recFromDb2WithSameId --- In BaseX version 9.2.4 the query executes very fast (2 - 3 seconds). In 9.3.2 I didn't wait to the end ... I aborted after several minutes because I suspected that something must be wrong. Both BaseX instances have allocated the same amount of memory (4096MB). The databases (db1 and db2) were created in the respective BaseX version from scratch and contain attribute and text indexes. They were optimized before executing the query mentioned above. All options and preferences are the same in both BaseX instances. I am using the GUI in Ubuntu 18.04. Here are some more details about the two databases: db1: - Size: 2255MB - Nodes: 97598775 - Documents: 7489 - Uptodate: true db2: - Size: 883MB - Nodes: 46317512 - Documents: 1 - Uptodate: true Does someone have an idea why there is such a difference in performance between the two BaseX versions?

Hello, First, thanks for the effort you're putting it to help BaseX users. I'm Using POST method to update BaseX database, I want to insert an xml node to an existing document calastone.xml in calastone database , if the node contains '<', it returns an error " Line 6): The value of attribute "value" associated with an element type "variable" must not contain the '<' character." code: <query> <text> let $message := '<Id>CTN53</Id>' return insert nodes $message as last into doc("calastone/calastone.xml") </text> <variable name='message' value='<Id>CTN53</ID>'/> </query> the same code without '<' adds the text correctly. how to solve this problem? Note that this is a question I posted on Stackoverflow, Link<https://stackoverflow.com/questions/60456387/passing-in-xquery-with-basex-p…>. Christian Grun suggested using < and > for attributes and CDATA for text nodes. After applying that solution, the xml stored is in this form <Id>CTN53</Id> This is not what I'm looking for. Is there any other more convenient solutions to store XML messages with Rest APIs? I know PUT method works fine but it overwrites the content of the document. Thank you.

Send byte[] to http response ?
by Mickael Desfrenes 07 May '20

07 May '20

Hello, Probably my ignorance, but I struggle to send a byte array (byte[]) from a java module to a restxq response. Something a bit like this: return (<rest:response> <http:response status="200"> <http:header name="content-type" value="application/pdf"/> </http:response> </rest:response>, SomeJavaModule:getSomeBytes($module_instance)) I know there is a binary module in BaseX but I tried various things and couldn't get the wanted output. I could probably write the bytes in a file and then use file:read-binary() but it's something I'd like to avoid. Any clue here ? Mickaël

Use of function-lookup in REST-XQ environment
by Mauro Mugnaini 04 May '20

04 May '20

Hi all, In order to have a "dynamic backend” implementation to REST-XQ invocations we used the fn:function-lookup() function but we are experiencing a strange behavior if the target looked-up function is an updating function that for example adds a resource to a database. Putting the provided files in the webapp folder of a fresh new BaseX latest (9.3.2) downloaded instance (adding "MIXUPDATES = true” setting in the .basex and with a database named DB already created inside) and invoking the REST function that calls directly the backend function with [1] the resource is correctly created on the database, by invoking the REST function that performs the dynamic lookup by using the fn:function-lookup() with [2] it completes without errors but the resource is not added to the DB. In our implementation the implementation modules are stored in the repo but the same behavior can be reproduced with “direct” function call as per my example. Is there any limitation in the looked-up function related to updating databases? Regards, Mauro [1] http:send-request( <http:request method="POST"> <http:body media-type="application/xml"/> </http:request>, "http://localhost:8984/store", <joe/> ) [2] http:send-request( <http:request method="POST"> <http:body media-type="application/xml"/> </http:request>, "http://localhost:8984/dyn-store", <joe/> )

BaseXClient command line run query requiring admin permissions?
by DYER Chris 04 May '20

04 May '20

I am trying to run some xquery scripts via the basexclient command line after logging in as a user with create permissions, but getting an error that admin permissions are required. basexclient connect to server using db_creator (with CREATE permissions) OPEN MyDatabase RUN test.xq → admin permission needed. Contents of test.xq : //database_info/version If I login as admin user, this sequence works fine. If I run this command via the rest interface in a browser and log in as db_creator, this also works. ( localhost:8984/rest/MyDatabase/?run=test.xq) If I run this command via the rest interface in a browser and log in a guest (permissions NONE) it says read permissions required (expected). Is there some limitation on running xq scripts from the command line client that requires admin permissions? Or am I missing some steps somewhere? Cheers, Chris
