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

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

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

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?

I ran it successfully on Windows with BaseX 8.6.5 and schematron-basex 1.2, both when I used proper file: URIs and Windows file system paths with backslashes. I used both the version of /docbook-mods.sch.xml that you sent me and a version with expanded entities (using xmllint --noent --dropdtd first). When I gave it too little stack size (-Xss108k) on startup, I could only provoke a "Stack Overflow: Try tail recursion?" BaseX error, not the "Too many nested template calls" Saxon error that you reported. Calling Saxon directly for applying iso_dsdl_include.xsl on the schema was also successful if heap and stack sizes were large enough. What happens when you apply your Saxon EE standalone, transforming the schema with iso_dsdl_include.xsl? Which version of Saxon 9 EE are you using?
