More authentication options?
by Peter Villadsen 27 Jul '18

27 Jul '18

I was previously using simple basic authentication, which will not pass muster within our organization. I therefore was happy to go to Digest authentication, which seems to have solved my problems for now. However, I was wondering if there will be an option for more advanced authentication scenarios, like certificates or possibly OAuth? Microsoft's SQL server SQL server has the concept of "windows authentication" where the windows security model is used (users who are already signed into windows do not have to present further creds). I don't know how that DB works when it runs on Linux though. Best Regards Peter Villadsen Principal Architect Microsoft Business Applications Group

Curious query optimization
by Sebastian Zimmer 27 Jul '18

27 Jul '18

Hi, I have a query which is optimized in a curious way in BaseX 9.0.2 (yesterday's snapshot). This is the original query: xquery version "3.1"; declare namespace tei ="http://www.tei-c.org/ns/1.0"; let $string := "string" let $fuzzy := false() return ( collection('ZK')/tei:TEI[ if (false()) then (.[descendant::text() contains text {$string} using fuzzy]) else (.[descendant::text() contains text {$string}]) ], collection('ZK')/tei:TEI[ if ($fuzzy) then (.[descendant::text() contains text {$string} using fuzzy]) else (.[descendant::text() contains text {$string}]) ] ) And this is the optimized one (newlines inserted by me for better readability): ( ft:search("ZK", "string" using language 'English')/ancestor::tei:TEI[parent::document-node()], ft:search("ZK", "string" using fuzzy using language 'English')/ancestor::tei:TEI[parent::document-node()] ) I'm curious why the second search is using fuzzy, even though the variable $fuzzy is false. I presume that query optimization is independent of the data, so you won't need the data to reproduce. But if you do, I can provide it. A database with enabled full-text index is required obviously.

xquery question: replacing multiple values
by Marco Randazzo 25 Jul '18

25 Jul '18

Dear all, I just started learning XQuery. I have the following XML: <Keywords> <Record Keywords="Bus"> 10 20 30 40</Record> <Record Keywords="Bus"> 11 21 31 41</Record> </Keywords> I'm using the following script to multiply by 2 values 30 and 31. for $v in /Keywords/Record let $v1 := xs:float($v/tokenize(.,"[|]| ")[3]) return replace value of node $v with replace ($v, $v/tokenize(.,"[|]| ")[3], xs:string($v1 * 2)) The output is correct (please tell me if my script is ok or if there are better ways to accomplish the same task). <Keywords> <Record Keywords="Bus">10 20 60 40</Record> <Record Keywords="Bus">11 21 62 41</Record> </Keywords> Now I would like to perform a similar operation but: case 1) applying the same operation on multiple elements (i.e. element 3 and 4) case 2) applying the same operation on all element (i.e. 1,2,3,4) For case 2) I tried the following (just removing the index [3]) for $v in /Keywords/Record let $v1 := xs:float($v/tokenize(.,"[|]| ")) return replace value of node $v with replace ($v, $v/tokenize(.,"[|]| "), xs:string($v1 * 2)) But I get the error: Item expected, sequence found: ("10", "20", "...") I also tried to write a script with two nested for loops, but unsuccessfully. Can you help me?

Parallelization
by Giuseppe Celano 24 Jul '18

24 Jul '18

I am having fun with xquery:fork-join() and I see that it really reduces evaluation time (!): I apply the same script to a collection of files, and if I use xquery:fork-join() it takes about half of the time. My computer has two cores. I was wondering what would happen if a computer had more cores/CPUs (or if the script were run on a computer cluster): could the function take advantage of all of CPUs/cores? In the future, will there be the possibility to maybe control this via parameters to pass to the function? Ciao, Giuseppe

Db directory
by Giuseppe Celano 23 Jul '18

23 Jul '18

Hi, I would like to create a database in a directory which is not "data" within the Basex folder. I used (within the GUI) the command <commands> <dbpath name="/newdirectory"/> </commands> but it does not work. How can I specify that? Thanks. Ciao, Giuseppe

Re: [basex-talk] load invalid xml

Sorry, I can just repeat what I’ve written in my last mail. XML parsers rely on well-formed input. Everything else would be a hack. And there are just too many possible error cases that would need to be considered by such “tweaks”.

Thank U Andy for your response, I have tried but it is giving schematron compilation error, but when I validate on Oxygen editor xmls got validated, as github documentation I am doing first schematron compilation then validating the XML, SO how can I resolve this error Now On Sun 22 Jul, 2018, 9:39 PM James Ball, <me(a)jamesball.co.uk> wrote: > Hello Dharmendra, > > Have you made sure that the Schematron is compiled before using it to > validate?
