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'

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.

All the best, Christian

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.

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.

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.
