pyBaseX: Python client for BaseX REST interface
by Luca Lianas 04 Feb '15

04 Feb '15

Hi everyone, I'm Luca and I work as a researcher and software developer at CRS4, a research center in Italy. I started using BaseX in one of the projects I'm involved (project's name is pyEHR, an openEHR based clinical data management framework https://github.com/crs4/pyEHR), this framework is written in Python and I needed a client for BaseX. In the beginning, I used the official Python libraries recommended on the wiki, but I recently started to develop a new library that can be used to interact with BaseX's REST interface. The library can be found on GitHub https://github.com/lucalianas/pyBaseX and can be downloaded using pip, it is still a work in progress and it still misses some features and a proper documentation (right now unittests are the only "documentation" that can be used to understand how the library works, sorry). I just wanted to inform the community :) Thanks for your attention and if someone wants to collaborate to the project please feel free to add your contribution. Cheers, Luca Lianas

Update Facility / Files - bug?
by Hans-Juergen Rennau 04 Feb '15

Dear BaseX-team, is there a problem concerning the update facility? Or do I have a blackout? Suddenly it seems as if the facility did not any more change files. doc.xml: <a> <b>XXX</b> </a> replaceValue.xq:replace value of node //b with 'YYY' call:basex -u -i doc.xml replaceValue.xq => no change Working on Windows 7, build 8.0 beta 6cedb1a (latest shapshot) Cheers,Hans-Jürgen

Hi, I am trying to compare to compare two nodes containing same double values with different scientific notation, matching the two nodes return false. But it should return true. Please help me out. ============================================== let $a := <a>123.4</a> let $b := <a>12.34E1</a> return deep-equal($a,$b) Expected : true Output : false Thanks Ankit

impressed! and already trying to run before I can walk
by Niels Grundtvig Nielsen 03 Feb '15

03 Feb '15

BaseX already looks/feels like a program I am going to enjoy using, even with the general challenge that I don't know enough about xQuery. I would welcome suggestions for anywhere to find a friendly introduction! My first specific challenge is trying to under the syntax for replace. In the code, I've managed to retrieve a single xml document where <title> contains "35. Andan" … I made a copy/paste error, and in this document the value of title should be '35. Andantino' instead of '35. Andantino mesto'. My experiment is obviously incorrect, so I'd welcome tips on what's wrong with it. //score[contains(title, '35. Andan')]//title replace value of (title) with '35. Andantino' Thanks in advance!

Seems problem with file:append()
by John Best 30 Jan '15

30 Jan '15

Hi Christian, How are you ? While using the file:append(), I encountered an issue/problem. Here's my sample xml file <Sample> <A>A</A> <A>An</A> <A>P</A> <A>D</A> <A>Ab</A> </Sample> I want to save the output of the above XML DB, to a new XML File and that too in sorted one- so my XQuery will be for $x in doc('sample')//A order by $x return file:append("C:\sampleSorted.xml", $x) but when I open the newly created file I didn't get the expected (sorted) output !! -- Have a nice day JBest

Adaptive serialization
by Christian Grün 28 Jan '15

28 Jan '15

Hi there, By default, BaseX 8.0 will use the new "adaptive" serialization method [1], which will be included in the new serialization spec: * It allows you to serialize attributes, namespace and function items (including maps and arrays) * Atomic values will not be escaped anymore. * Items will be separated with newlines The new default can already be tested [2]. As an example, the following query... "me & you", map { "B": "C" }, <x y='z'/>/@y …will be serialized as follows: me & you { "B": "C" } y="z" Please be aware that the new default serialization may generate different results, so please check your existing applications when switching to the new version! Cheers, Christian [1] https://www.w3.org/Bugs/Public/show_bug.cgi?id=27498 [2] http://files.basex.org/releases/latest

Feature request
by Johan Mörén 27 Jan '15

27 Jan '15

Hello! We have been using the hashing module to calculate md5 checksums on binary files successfully for a while. But last week we received our first really large file (4.3 gb) and our script threw a *java.lang.OutOfMemoryError: Requested array size exceeds VM limit* We are currently using the 7.8 version of BaseX. I suspect that BaseX materialize the stream returned by file:read-binary as a byte-array when we call the hash:md5 function. This is a snippet of our script where the problem arises ... let $binary := file:read-binary($filePath) let $checksum := lower-case(xs:string(xs:hexBinary(hash:md5($binary)))) ... I think a nice feature to add to BaseX could either be a new function in the file-module called file-checksum($algorithm) that calculates checksum on files in a streaming fashion. Or perhaps an option to the hashing functions that indicates that you want them to use streaming. Regards, Johan Mörén
