Full text score with or
by Andy Bunce 23 Nov '14

23 Nov '14

Hi, I want to score searches with multiple conditions e.g. let $data:=( <r><a>red apple</a></r>, <r><a>blue lagoon</a></r>, <r>fish and chips</r>) for $hit score $s in $data[ a contains text("red") or b contains text("fish")] return $s In 7.8.2 it always returns scores of zero. In version 7.6 it returns numbers like 0.6201145069582775 0.4528324252639413 Is this bug? Regards /Andy

stream binary responses from http:module
by Johan Mörén 10 Nov '14

10 Nov '14

Hi I have built a small client in XQuery that fetches zip files from another remote service using the http-module and stores them on disk with the help of the file-module. Some of the returned zip files are really large and BaseX seems to need to materialize the files in memory before writing them to disk resulting in out of memory errors for some files. Is there some way read the response in a more streamable fashion when using the http-module? I tried using the fetch:binary function successfully but i really need the more extended functionality of the http-module. #results in out of memory if the zip file is too large file:write-binary("file.zip", http:sendrequest(...)[2]) #works all the time. file:write-binary("file.zip", fetch:binary(...)) Regards, Johan

JSON or JSONML output formatting
by Zachary Pride 16 Jul '14

16 Jul '14

Hello, I've been playing with BaseX lately and all-in-all am very impressed. Something I'm wrestling with however is the JSON output options. I've got various web applications that would really be simplified by receiving JSON straight away for the obvious scripting benefits. The JSON method has been giving me a lot of grief, stipulating rules I'm not sure how to follow. right now I have an element that "is typed as string and cannot be nested." I've been able to get JSONML to output but the JSON is this morass of nested Arrays... Attributes seem to get transformed into Objects but elements/tags and their values are pushed into Arrays for some rationale - which I suppose is on purpose. My question is how can I get Objects for simple key:value properties from <tag>value</tag> 's. Are there options I'm not utilizing? Would it be feasible to transform the XML output to some middle form first - setting it up to become Objects, before serializing it to JSON? Thanks!

Status of multipart
by Marco Lettere 08 Jul '14

08 Jul '14

Hello all, I would like to know what the status of multipart HTTP request currently is. I read from the docs that it's experimental but to me it feels like there's currently a regression (is there any working example?). I have some requests that were working correctly up to 7.6.1 AFAIR. From 7.8 on (including latest) I always get this error message when posting multipart requests: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/> <title>Error 400 Stopped at .../restxq.xqm, 106/10: [experr:HC0004] Invalid request element: No body specified for http:part.</title> </head> <body> <h2>HTTP ERROR 400</h2> Problem accessing /multipart.

Java interop (java.net.URI) problem
by Marc van Grootel 29 Jun '14

29 Jun '14

Hola, So, this is my very first post here. I started my first 'serious' xquery project after doing xslt mostly for a long long time. Soon I hope to put something on github. I needed to parse information from a URL and thought I could use java.net.URI instead of doing the hairy URI string parsing myself. As far as I can see this should work according to the documentation. But it's not: declare namespace uri = "java.net.URI"; let $uri := uri:new('http://basex.org') return uri:get-host($uri) It gives me: [FORG0006] Invalid call of Java function: URI.getHost(xs:anyURI). Any idea what I'm doing wrong here? --Marc

BaseX 7.9: The Summer Edition
by Christian Grün 29 Jun '14

29 Jun '14

Dear subscribers, in the midst of summertime, we provide you with a great new version of BaseX, our XML database system and XQuery 3.0 processor! This is what you get: XQUNIT - Unit testing has been improved a lot. All test functions will now be evaluated separately; this way, updates can be performed within test. - with the new TEST command, all test modules in a specified directory can be evaluated. - tests can be invoked from within the GUI editor and project view. - on command-line, the -t flag can be used for the same purpose. RESTXQ - Custom HTTP methods can be defined via %rest:method - Error handling has been improved and aligned with try/catch REST - The "run" operation allows execution of server-side command scripts DATABASE MODULE - parsing options added to db:create, db:add and db:replace As usual, various minor bugs and inconsistencies have been fixed in the latest version; check out our documentation and the GitHub history for more details! The latest version is available at http://basex.org. We are looking forward to your feedback, Christian BaseX Team

BaseX 8.0 and millions of documents
by Fabrice Etanchaud 26 Jun '14

26 Jun '14

Dear all, Will BaseX 8.0 address the speed problem when it comes to replace a document in a several millions documents' collection ? Currently, I have to insert documents in a XML master document and then use XQuery update to replace them. Using replace would be so simple ! Best regards, Fabrice Questel/Orbit

How to prevent formatting of specific nodes
by Erdal Karaca 26 Jun '14

26 Jun '14

Hi, Using org.basex.io.serial.Serializer to serialize nodes from a DB, I want to be able to prevent formatting/indentation of specific nodes. For example: <body> <pre>test</pre> </body> When serializing something like that, the output will be: <body> <pre> test</pre> </body> The desired output would be: <body> <pre>test</pre> </body> I.e. the pre elements must not be indented. I only found this parameter for the serializer cdata-section-elements Which I guess would enclose the contents of the pre elements by CDATA: <body> <pre><![CDATA[test]]></pre> </body> Which would not be the desired output. Thanks!

URN as library module namespace
by Carl Leitner 26 Jun '14

26 Jun '14

Hi, I am trying to do a “REPO INSTALL” a library module which has a namespace which is an URN, urn:ihe:iti:csd:2013, but am receiving the error: [bxerr:BXRE0002] Namespace URI is invalid: 'urn:ihe:iti:csd:2013'. I noticed that URNs are not discussed here: http://docs.basex.org/wiki/Repository#URI_Rewriting Taking a look here: http://www.w3.org/TR/2014/REC-xquery-30-20140408/#doc-xquery30-ModuleDecl I don’t see anywhere where URNs are explicitly disallowed. Any suggestions would be appreciated. Cheers, -carl
