One of the map element causes SEPM0017 error
by Arkadiusz Bok 06 Apr '20

06 Apr '20

Hi, I'm trying to run one of unchanged code example from book "XQuery: Search Across a Variety of XML Data 2nd Edition" from publisher O'Reilly Media. |(: XQuery by Priscilla Walmsley (c) 2016 Priscilla Walmsley:) | |(:Example 13-4 Serialization parameters in a map :) xquery version "3.1"; declare namespace prod = "http://datypic.com/prod"; let $map := map { "method": "xml", "version": "1.0", "indent": true(), "cdata-section-elements": (xs:QName("prod:desc"),xs:QName("prod:name")), "use-character-maps": map { "«":"<%", "»":">%" } } let $element := <prod:name>Fleece Pullover</prod:name> return serialize($element,$map) | I'm using BaseX 9.3.2 to do this. But when I'm trying to run code, I get error: |Stopped at C:/Users/Arek/AppData/Local/Temp/example1304.xqy, 16/17: [SEPM0017] item() expected, xs:QName+ found: (Q{http://datypic.com/prod}desc, Q{http://datypic.com/prod}name) | When i remove 9 line with /cdata-section-elements/ element, code runs. Whether is it problem with XQuery implementation or with code? ||||

Problem with attribute parsing?
by Peter Villadsen 06 Apr '20

06 Apr '20

Hello I was doing some experiments and I ended up with this: let $c := <Class Source='{ttt'></Class> return $c/@Source When this is compiled in the BaseX GUI app, an error message ensues: Error: Stopped at ... /file3, 1/30: [XPST0003] Expecting '}', found '''. Query: let $c := <Class Source='{ttt'></Class> return $c/@Source Query plan: <QueryPlan compiled="false" updating="false"/> Surely that is not correct? If I add a } there, everything is fine: let $c := <Class Source='{ttt}'></Class> return $c/@Source I don't think there is an XML requirement forcing escaping start brace ('{') inside an attribute value? I know that XQuery supports <X A='{...}' /> where the inside of the {} is evaluated to give the value for the A attribute, but the example above is not XQuery, just an XML literal. I am sure I would have noticed this if it were a general problem. Best Regards Peter Villadsen Principal Architect Microsoft Business Applications Group

EXPath package dependencies
by Clark, Ash 01 Apr '20

01 Apr '20

Hello, I’m trying to define the dependencies for a general-purpose EXPath package, one which I plan to use in both eXist-db and BaseX. So far I’ve got this in expath-repo.xml*: <dependency processor="basex"/> <dependency processor="http://exist-db.org" semver-min="4.0.0"/> Based on the spec, I gather that `//dependency/@processor` is supposed to be non-exclusive. However, when I try to install the package into BaseX, I get the error “Package version is not supported.” Is this a bug? Is there something else I should do? Warmly, Ash * https://github.com/NEU-DSG/wwp-public-code-share/blob/counting_robot/counti… Ashley M.
