Strange compilator behavior ?
by jean-marc Mercier 09 Oct '17

09 Oct '17

Hello BaseX team ! I lost some time to detect an error in my code, and wonder if there is a minor bug into the BaseX compiler. Here is the test let $elt as element(*)*:= <universe id="yolo"></universe> for $d in (1 to 1) return let $idd := $elt[d]/@id return ($elt[$d]/@id,$idd) output : id="yolo". (Hence missing the second "yolo", because the correct query is : let $idd := $elt[$d]/@id) However I can't figure out why the BaseX compiler ran this query ? Shouldn't it refused the compilation and point out this error ? Cheers, Jean-Marc

Directory from which xml files are loaded
by helmut 09 Oct '17

Hi everyone. I am using basex in embedded mode. I set the basex base directory with System.setProperty("org.basex.path", path). In this path I have a .basexhome file which defines REPRO, DBPATH ... and so on. For loading an xml file to the database I use e.g. new Add(path, file).execute(context). "file" is given as an absolute path. However, when I query the database I get the error [FODC0002] Resource 'path/xyz.xml' does not exist, with a path which points now to my the system property user.home or user.dir. How can I change this behaviour? What I am missing? I don't want to change user.home or user.dir, because other things might depend on the properties. I read through the configuration guide and many other pages, but didn't find something. http://docs.basex.org/wiki/Configuration Thanks very much, Helmut

put with relative uri
by Andy Bunce 06 Oct '17

Hi, I notice fn:put() appears to be resolving uris relative to the working directory, as the file module does, rather than static-base-uri() as fn:doc() does. I dont think it was always like this and it seems to against the intent of the spec[1]? /Andy [1] The external effects of upd:put are implementation-defined, since they occur outside the domain of XQuery. The intent is that, if upd:put is invoked on a document node and no error is raised, a subsequent query can access the stored document by invoking fn:doc with the same URI. https://www.w3.org/TR/xquery-update-10/#id-upd-put fn:put(<a/>"test.xml") --------------------------- fn:doc("test.xml") (: [FODC0002] Resource 'C:/.../test.xml' does not exist. :)

Re: [basex-talk] Why am I getting this error with the prolog statement

Hi Dave (cc to the list), > I am creating xml on an IBM mainframe. The code page used on mainframes > is defined as EBCDIC 0037. https://en.wikipedia.org/wiki/EBCDIC_037 As EBCDIC 0037 is limited to 256 characters, a simple mapping should suffice to convert your text to ISO-8859-1 (see the mapping table in the Wikipedia entry you referenced). It should be lightning fast, no matter if you do it in assembler or in XQuery. Hope this helps, Christian

Why am I getting this error with the prolog statement
by Dave Day 03 Oct '17

Hello list. Another newbie question. I am creating a file in UTF-16, Big-endian. I am putting a 2 byte BOM sequence of x'FEFF' as the 1st two bytes, followed by a prolog statement identifying this as UTF-16 code. I then ftp this file to my desktop in binary to maintain the encoding. Below is a cut-n-paste of the 1st few bytes as it looks on the mainframe box. --------------------------- Ú.<?xml encoding="UTF-16" ?> FF46A9948989889877EEC6FF7466 EFCF743055364957EF436016F0FE The way the display is within ISPF, each byte has one character on two lines, so the 1st byte, FE should be read as col 1 of both lines, and so forth. When I try to create a new database I get the following from Basex. Command: CREATE DB d100217 :zxpf.ftp.download/apf1.v2r3.xmldata Error: "d100217.xml" (Line 1): Content is not allowed in prolog. Help greatly appreciated. Regards, Dave Day
