html serialization select option selected vanishes
by Andy Bunce 13 Jan '14

declare option output:method "html"; declare option output:html-version "5.0"; <select><option value="a" selected="selected">a</option> <option value="b" bad="bad">b</option></select> Result <!DOCTYPE html> <select> <option value="a">a</option> <option value="b" bad="bad">b</option> </select> Note bizzare vanishing of selected="selected". Seems to only happen only for option with selected="selected" for all html versions. /Andy

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? Regards /Andy [1] http://docs.basex.org/wiki/HTTP_Module [2] http://wiki.apache.org/tika/TikaJAXRS

Re: [basex-talk] A free-form XQuery through RESTXQ?
by Neven Jovanović 11 Jan '14

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. I also understand now how to call functions provided by various BaseX modules. The XPath solution will come in useful as well.

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

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
