C++ API for BaseX v0.0
by jean-marc Mercier 10 Jan '14

10 Jan '14

Hi all, C++ users could be interested in this first "quick and dirty" version of a C++ API for BaseX, located at https://github.com/JohnLeM/BaseXCPPAPI. Even if this v0.0 version is built upon Visual C++ 2012 Express, the C++ code should be multi platform. Hence, if there is any C++ / Unix / gcc BaseX users, do not hesitate to ask for a make file. To BaseX team : you could also be interested to including a cleaner version of this work to your API set for your C++ clients. This API is built upon : - boost::asio libray for the TCP connector (http://www.boost.org/) - PugiXML (https://code.google.com/p/pugixml/) for a lightweight C++ parser with XPATH 1.0 support. The provided example is a simple construction of an integer list. Cheers Jean-Marc

baseX and XInclude
by CLEMENT, Matthias 10 Jan '14

10 Jan '14

Hello, I am trying to load a database consisting of several xml files that use XInclude such that one file will include other files: <?xml version="1.0" encoding="utf-8"?> <?xml-stylesheet type="text/xsl" href="dfs.xsl"?> <dfs xmlns:xi=http://www.w3.org/2001/XInclude> <xi:include href="file1.xml" parse="xml"/> <xi:include href="file2.xml" parse="xml"/> </dfs> baseX does not seem to be able to understand the Xinclude command. Is this feature missing or is there a way to load my database ? Regards, M.

Hi, waiting for Christmas, i was playing with Basex. I had no problem for using a short Thesaurus i built a few days ago. But when i tried to use the extended one (26Mo), i get this error message. Is this a problem of mine ?

by Charles Foster 07 Jan '14

07 Jan '14

Calling all BaseX and XML aficionados. The XML London 2014 conference takes place on 7/8th June 2014 at University College London. We are looking for speakers for this event. Speakers go for free. Call for papers is open and closes 10th March. Submissions do not HAVE to be final papers by that date, extended abstracts which succinctly describe the contents of a final paper will suffice. If successful, final / polished papers will need to be completed by 9th May. The conference has themed topics. However, papers of outstanding quality or novelty are ALWAYS welcome at XML London, regardless of whether they fit into any of the conference theme topics. The conference theme topics are as follows Document Databases :- The future of search over structured and unstructured data with NoSQL solutions. Applied XML :- Real life use cases of where XML technologies have been beneficial. XML Elephant :- Coping with and processing huge volumes of XML and Big data effectively. Teaching XML :- XML technology is cool, why so? what can it do for people who are not using it? Modern Publishing :- Single sourcing, delivering content to a Web of Devices using Markup technologies such as DITA, S1000D, DocBook, HTML, EPUB, etc. The Semantic Web :- The world of RDF, RDFa, triples, linked data, semantics and SPARQL.

BaseX for noobs: C++ API ?
by jean-marc Mercier 06 Jan '14

06 Jan '14

Hi all, going back to the root... I am trying to connect my favorite C++ tools to BaseX. Unfortunately, I am using visual C++ 12 Express under windows 7. It seems that windows users will not be able to use the existing BaseX API C connector, and need another one. Thus I started to code a C++ BaseX API connector. Writing a API connector is quite difficult for me, since I don't have the required networks knowledge. Has somebody already some code to that purposes ?

Hi,all, I have a restxq web service to do insert or update xml doc , which is called by many clients to provide xml data to db, there will be 500000 files to provide to basex server. I have found some problem few times : 1) often, after insert tens of thousands xml file, the db "list" will cause error,cause db corrupt, I don't know why, How, please help me. 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。
