Variable value nulled when passed to an xsl (smaller DB)
by France Baril 16 Jan '14

16 Jan '14

Hi, I am using BaseX 7.8 beta 3b557bd. When I pass a variable where the value is provided by a function ( *let **$string-variable* := *freeze-test:get-localized-string*('en-us', 'application')) that extracts the data from the database, I cannot pass it as a parameter to an xslt. It nulls the value. I attached a code sample and a simple database that holds a single file. In the sample, if you replace the line : *let **$string-variable* := *freeze-test:get-localized-string*('en-us', 'application') with *let **$string-variable := *'application', you'll notice that the value is output correctly. The issue is not with getting the value. When using the original variable setting (*let **$string-variable* := *freeze-test:get-localized-string*( 'en-us', 'application')), the debug line (*let* *$debug* := *file:write*( 'debug-string-var.txt', *$string-variable*)) does output the extracted value in the .txt file correctly, which means the variable $string-variable has been set, it just doesn't survive being passed as a parameter to xslt:transform. Note that this used to work in BaseX 7.7.2. The fact that the variable gets nulled is a completely new phenomena. To access the test function: http://localhost:8984/test/xsl-params Thanks, France P.S. You can disregard the previous request with larger files (sent to the moderator by the mail server). It looks like old files were still indexed, weighting on the DB size. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

Experience for management of tons of xml doc using exist-db
by easy 15 Jan '14

15 Jan '14

Hi,all, Based on my discontinuously near ten years experience using exist-db, I made a plan to using exist-db to management more than millions people's EHR, till now, it almost can work, here is what I have done: 1) split the large quantity of doc into small collection( not one collection for one people, but one doc for one people), target to speed query personal info and insert new record nodes. 2) with the kind developer 's help , we can using new range index to quick query big data based on some conditions. 3) using the backup policy to do backup. ... But, there are still some difficult to worry about: 1) exist-db often caused corrupt for a heavy load query, and this often cause db recover fail. and how to avoid heavy load query to affect other query? 2) when will use re-index? after corrupt? the re-index process is very time consumed. how to accelerate re-index? 3) how to control concurrently update db? often this cause the db stop responding to xquery, and as 1). everyday there will more than 1000000 files add to the db, so this is a difficult problem. 4) how to control backup copys ? the backup file will cost large disk space if all old copy exist. Thanks for advice -- 此致 easy 莫愁前路无知己，天下谁人不识君。

Hello, I’m trying to keep up to date with BaseX and test integrating the BaseX snapshot versions (at the moment 7.8 beta) into our environment. Here is my question: How do I build the structure that can be downloaded from the website containing all files and folders. Running e.g. mvn package yields only the API and core jar files. What am I missing?

adding too many documents is slowing down collection operations
by Fabrice Etanchaud 14 Jan '14

14 Jan '14

Dear all, I'm working on a collection containing tens of millions of documents, updated weekly. My first guess to store these documents was to simply db:add/replace/remove them. This solution is slowing things down as the count of documents increases. For example, opening one collection takes up to 4 minutes. I believe that the document list is an in memory structure. Is there a way to speed things up, or do I have to change sides with the following guess, in order to reduce the 'physical' document list size : 1.group documents in 'logical' documents on insertion (fewer documents containing new or updated documents under a root xml element) 2. remove the old version of these documents in the previous 'logical' documents with xquery update. Has anybody already find that problem, and a workaround ? BaseX is just fantastic ! Best regards, Fabrice Etanchaud Questel/Orbit

Trying to use http:request to emulate curl -X PUT -T xxx.pdf
by Andy Bunce 12 Jan '14

12 Jan '14

Hi, I want to use the tika server [2] to extract text from pdfs. This working using curl as the client curl -X PUT -T aa.pdf http://localhost:9998/tika However I want to use the http module[1] I have tried: let $file:="C:\tmp\aa.pdf" let $request := <http:request method='PUT' > <http:body media-type="application/octet-stream">{ fetch:binary($file) }</http:body> </http:request> let $r:= http:send-request($request,$tika) I have tried this with various values for http:body/@method with no sucess. The content-length header from this does not match the one sent by curl. This did not work either (no body?): let $file:="C:\tmp\aa.pdf" let $request := <http:request method='PUT' > <http:body media-type="text/plain" src="{$file}"/> </http:request> let $r:= http:send-request($request,$tika) Any ideas?

Arve, great! It was just what I needed. My function now looks like this: function page:cpxq-postman( $query as xs:string*) { let $q := xquery:eval($query, map{ '' := db:open('crobib') }) return element v { $q } }; And it works as expected.

A free-form XQuery through RESTXQ?
by Neven Jovanović 11 Jan '14

Hello, my name is Neven Jovanovic, and I have beginner's problems with BaseX RESTXQ interface. We'd like to have a textarea form where users would compose their own XQueries to be executed over our database (just querying it, no updating etc). I have already written a cgi Perl script which does this through BaseX REST interface. Now I'd like to do the same with RESTXQ, but I'm missing something. For testing purposes, we use the .zip version of 7.7.2 release, on Linux Mint Debian (locally), started with .basexhttp. Everything works OK, the db is there etc. Here is the form added to the existing restxq.xqm: <h3>Write an XQuery</h3> <p>Compose your own XQuery.</p> <form method="post" action="compoxq"> <p>XQuery:<br /> <textarea name="query" rows="5" cols="80"></textarea><br/> <input type="submit" /></p> </form> Here is the function added to the restxq.xqm: (:~ : A free-form XQuery. :) declare %rest:path("/compoxq") %rest:POST %rest:form-param("query","{$query}", "(no query)") function page:cpxq-postman( $query as xs:string*) { let $q := $query return element q { collection("crobib")//$q } }; Submitting the following form string: //*:person I get these results at <http://localhost:8984/compoxq>: <q> //*:person //*:person //*:person //*:person //*:person (lots more...) </q> Some query obviously is being performed, but instead of results, I get the query string.

Possible bug in BaseX interpreter, might be the introspection module ?
by jean-marc Mercier 11 Jan '14

11 Jan '14

Hello, I have a quite strange behavior, that might be a bug in the introspection module. I am just describing it, and will work a bit to produce a reproductible code if you don't have a quick clue about the problem. I created a map of string to functions, called $common:MapIntrospecting, generated by the introspection module. The following code works perfectly (you can't run it, but believe me :) declare variable $map := map:entry("Alimentation:nodes#1",Alimentation:nodes#1); declare variable $nodes := a big node... let $fun_1 := map:get($map,"Alimentation:nodes#1") let $fun_2 := map:get($common:MapIntrospecting,"Alimentation:nodes#1") return $fun_2($nodes) And now, the following code (I just cut the useless first line) produces a spurious and ferocious exception let $fun_2 := map:get($common:MapIntrospecting,"Alimentation:nodes#1") return $fun_2($nodes) Any clue ? Improper use? Potential bug?

restxq file upload with no file selected
by Andy Bunce 11 Jan '14

11 Jan '14

Hi, In the case where I submit a form with an input type= "file" without selecting a file. The server side map [1] has one entry with empty name and content. It seems to me it would be more useful to return an empty map in this case. Regards /Andy [1] http://docs.basex.org/wiki/RESTXQ#File_Uploads

tiny request
by Rob Stapper 11 Jan '14

11 Jan '14

Hi, I've a tiny request. It concerns the inputbar in the BaseX-GUI in query-mode with a opened database. It used to work that after typing a slash ( '/') in the inputbar all the child-elementtypes were shown in a dropdown box. Now this only works for the root (initial slash) but not anymore for under laying elements . For these elements the dropbox is only presented after typing a character. The dropbox then only contains the child-elementtypes that start with this character(s). So I'm not presented with all the child-elementtypes anymore, which is too bad because I used this option for finding my way within the XML-structure. For example: <a> <b> <d1> </d1> <e1> </e1> </b> <c> </c> </a> Inputbar: / gives a dropbox with 'b' and 'c'. That's nice. Inputbar: /b/ gives nothing. I would like to see: 'd1' and 'e1' Inputbar: /b/d gives a dropdown with 'd1'. Could this be fixed? I think it's such a nice little option.

Java bindings - ambiguous Signature
by Andy Bunce 11 Jan '14

11 Jan '14

Hi, In my ongoing attempts to use various Java libraries, without writing any Java myself, I have trying Apache Tika. (http://tika.apache.org/1.4/api/org/apache/tika/Tika.html). With the tika jar on the classpath I hoped the following would work: import module namespace tika = "java:org.apache.tika.Tika"; declare namespace File="java:java.io.File"; let $file :=File:new("xx.pdf") return tika:parse($file) It generates the error Signature 'org.apache.tika.Tika.parse' is ambiguous Which maybe it is from some perspectives :-). I hoped some type information might be available in the $file variable to resolve this, but it appears not. I was wondering about the possibility of using Java type at the XQuery level e.g. let $file as java:java.io.File :=File:new("xx.pdf") Is there any way to avoid writing the couple of line Java class shim for this and similar cases? Regards /Andy

Incremental fulltext update?
by Florent Heyworth 11 Jan '14

11 Jan '14

Hi all I've been experimenting with BaseX - and I'm quite pleased with its capabilities - however I'm hitting a wall where the fulltext index is concerned. Here's the use-case: - Web application analyzing media (news, etc.) on a large scale - Frequent inserts (metadata about news) by many clients (ca. 40+ million documents per year) - Online Full-text search is a must Every time data is inserted into a database the full-text index is invalidated. Because of the online full-text search capability requirement a 2-stage update process (store to temporary database, batch update to main database and optimize full-text index afterwards) is unfortunately not an option. Are there plans to provide for incremental full-text update capacity or is this not an option? Thanks for any feedback and kind regards Florent

bug in QueryCollection.java example
by Morris 11 Jan '14

11 Jan '14

Hi there I tried out the QueryCollection example from github and discovered there is a bug in line 47 ``` for $doc in collection() ``` causes [FODC0002] No default collection available. I think it should be ``` for $doc in collection("Collection") ``` then the error is gone.

add-dayTimeDuration-to-date
by jean-marc Mercier 11 Jan '14

11 Jan '14

Hello, I am trying to add dates and duration through BaseX, in conformance with http://www.w3.org/TR/xpath-functions-30/#func-add-dayTimeDuration-to-date. However, BaseX interpreter does not recognize the function add-dayTimeDuration-to-date, nor op:add-dayTimeDuration-to-date. Did I misunderstood something ? Thanx for your answer, Cheers, Jean-Marc

I don't know how to control the concurrently update db. 2) I often found there will automatically startup a basexhttp service in the server even the manually started service still run. ???, maybe the "basexhttp stop" command can't stop the service though it say stopped. the restxq service code as fellow: ---------------------------------------------------------- declare %output:method("xml") %output:omit-xml-declaration("no") %output:media-type("application/xml") %updating %rest:path("/add_ehr_doc") %rest:POST("{$body}") %rest:header-param("pid","{$pid}") %rest:header-param("doc_id","{$doc_id}") %rest:header-param("op","{$op}","APND") function ehr:add_ehr_doc( $body,$pid as xs:string,$doc_id as xs:string,$op as xs:string ) { let $dbname: ='myehr' let $fp:=substring($pid,1,6)||'/'||substring($pid,7,8)||'/'||substring($pid,15)||'.xml' (: pid is a patient id code as: area_code-section_code-serialnumber :) return try{ if (db:exists($dbname,$fp)) then ( insert node ($body//*:DataSet) into (doc($dbname||"/"||$fp)//*:BasicDataset), db:output(<msg><Ack>200:append</Ack><Url>{$fp}</Url></msg>) ) else ( db:add($dbname, $body,$fp),db:output(<msg><Ack>200 new add</Ack><Url>{$fp}</Url></msg>) ) } catch *{ db:output(<msg><Ack>201 error</Ack></msg>) } }; -- 此致林晓东莫愁前路无知己，天下谁人不识君。
