Inconsistent Error Handling: XSLT-Based Resource Fails, While Pure Resource Completes Validation #171

Closed gediminasre closed 4 months ago

gediminasre commented 5 months ago

Dear Repository Maintainer,

We are encountering an issue where there is a discrepancy between Pure and XSLT validations using the same Schematron file in version 7.1.2 of your library.

Description:

During our validation process, Pure validation logs an error message to the console but continues and completes the validation. In contrast, XSLT validation, using the same Schematron file, throws the same error and halts the validation process.

Error Messages and Files:

Issue:

For some reason, the Pure validation catches the error but does not re-throw it, whereas the XSLT validation re-throws the error, causing it to stop. This difference in behavior is causing inconsistencies in our validation workflow.

Could you please investigate why the XSLT validation behaves differently from the Pure validation in this scenario? Any insights or suggestions for achieving consistent behavior would be greatly appreciated.

Thank you for your assistance and for providing such a valuable tool.

Best regards, Gediminas

@phax perhaps you had some time to look at this?

phax commented 4 months ago

@gediminasre thanks for the reminder. Indeed there is an explanation for this. a) Pure and XSLT behave totally different because they support a different condition language (XPath vs. XPath + XSLT) and the execution logic is different (Java vs. XSLT element iteration) b) See e.g. #169 for another very similar case on why they behave differently

However, I acknowledge the inconsistency, that the error is not re-thrown and I will look into it

Thanks for coming back @phax

To clarify, XSLT should ideally follow the Pure validation pattern and not throw the error, allowing the full validation process to complete.
