How to check an element's type against an XSD simple type
Hi everybody, I'm trying to compose XML documents for SEPA transactions via BaseX. I would like to check certain data against the corresponding schema before putting them into the document, e.g. BIC identifiers. In the xsd, there's a simpleType definition for BICs: <xs:simpleType name="BICIdentifier"> <xs:restriction base="xs:string"> <xs:pattern value="[A-Z]{6,6}[A-Z2-9][A-NP-Z0-9]([A-Z0-9]{3,3}){0,1}"/> </xs:restriction> </xs:simpleType> I hoped it would be as simple as declare default element namespace "urn:iso:std:iso:20022:tech:xsd:pain.001.003.03"; let $node := <BIC>GEN0DEM1MPW</BIC> return if(string($node) instance of BICIdentifier) then (true() (: process... :)) else (false() (: report error :)) But, as I learned now, BaseX doesn't support import of schemas. Thus, I receive the error message "Unknown type: Q{urn:iso:std:iso:20022:tech:xsd:pain.001.003.03 }BICIdentifier". Is there some workaround (other than rebuilding regular expressions from schema to xquery)? Best regards, Ulrike.
Hi Ulrike, The Validation Module should help you here, in particular validate:xsd-report [1]. It allows you to pass on file URIs or XML fragments as arguments.

I hoped it would be as simple as
declare default element namespace "urn:iso:std:iso:20022:tech:xsd:pain.001.003.03";
let $node := <BIC>GEN0DEM1MPW</BIC>
return if(string($node) instance of BICIdentifier) then (true() (: process... :)) else (false() (: report error :))

PS: If it’s only about BIC validation, you can obviously use standard XQuery: declare variable $BIC-PATTERN := '[A-Z]{6,6}[A-Z2-9][A-NP-Z0-9]([A-Z0-9]{3,3}){0,1}'; let $node := <BIC>GEN0DEM1MPW</BIC> return if(matches($node, $BIC-) then 'well done' else 'sigh' On Fri, Mar 11, 2016 at 11:20 AM, Christian Grün <christian.gruen@gmail.com> wrote:

Sorry, a last one: Here is the fixed version of the query: declare variable $BIC-PATTERN := '^[A-Z]{6,6}[A-Z2-9][A-NP-Z0-9]([A-Z0-9]{3,3}){0,1}$'; let $node := <BIC>GEN0DEM1MPW</BIC> return if(matches($node, $BIC-PATTERN)) then 'well done' else 'sigh' Most importantly, you’ll have to wrap your regex pattern with ^ and $ in order to ensure that there are no other heading or trailing characters in the BIC string.

Dear Christian, Thanks a lot for your suggestions. But as I stated in my original mail, I didn't plan to translate schema definitions to regular expressions... Neither did the validation module work as I hoped: Unfortunately the element in question is defined locally, not globally ("Validation failed: Deklaration des Elements 'BIC' kann nicht gefunden warden."). So, back to regex, I suppose! Best regards, Ulrike. -----Ursprüngliche Nachricht----- Von: Christian Grün [mailto:christian.gruen@gmail.com] Gesendet: Freitag, 11.
