I changed my schema slightly so that, instead of using a sequence of restriction-extension for a string type, I'm using an extension followed by a restriction. My problem comes in validating an instance of the XML, where I'm getting the message:

Attribute '{urn:Afieldtypes:v1}qsType' is not declared for element 'address'

This happens when I use the built-in validating engine, but not when I use the others (e.g. MSXML 4.0 DOM Parser, .Net XML Parser).

I'd like to not have to always pick a validating engine. Is there something wrong with my code or can I set a different default validating engine? I'm on version Professional Edition 2006 Version 2, build 591d.

I've attached a stripped down version of the schema that gives the same error on the sample xml.

I appreciate any help I get.

Hi Andy,
this could be a known bug of Xerces-C, bug#1714 (see
http://issues.apache.org/jira/browse/XERCESC-1714).
As for the 'validate' button, it cannot be bound to a different
validator, and you will have to click the arrow next to it and pick a
custom one.

Sorry,
Alberto

Thanks, Alberto. I've moved my new schema into production, accepting that I'll have to select a custom validator each time I need to validate. I figure this will be fixed some time soon.

Now onto my next problem... I'm developing a new XSLT and want to validate my output. When using Stylus Studio, under Scenario Properties, Validation, the built in validator doesn't work - this I already know. But, when I try to "Use custom validator", it does not allow me to enter a schema. Not allowing this to stop me, when I try to run my XSLT (all still within the SS development environment) and validate against my schema, I get the following error (which references my output file):

Running custom validation engine .NET XML Parser...

Command line failed:
C:\PROGRA~1\STYLUS~4\bin\Custom Validation Engines\XmlValidator\XmlValidator.exe "g:\ag\WO63219.AG\20071001T14_qs.xml" auto
Initial Directory:
(null)
Error Message: The system cannot find the file specified.

I think I should still be allowed to enter a schema, when I choose a custom validation engine. I have tried selecting the build-in validation engine, entering the schema, and then changing to a custom validation engine. This leaves my schema in a non-enterable "Validate against these schemas" text box, but still gives me the above error.

I'm now running with the 2007 Professional Suite, build 894m.

Short of saving my XSLT output to a file, re-loading it, associating it with my schema, selecting a custom validation engine and run... is there another way around this nuisance?

Hi Andy,
the list of schemas to preload is not available for the .NET validator as it doesn't support it (you could use the Saxon-SA or the Java built-in validators if you need to specify them). If you are forced to use that validator only, then you could change the XSLT stylesheet to create in the output XML the xsi:noNamespaceSchemaLocation attribute to bind it with the schema.

As for the error that occurs when validating, can you check if you have the C:\Program File\Stylus Studio....\bin\Custom Validation Engines\XmlValidator\XmlValidator.exe file? As the custom validators are installed on demand, it could be that it is missing.

Hope this helps,
Alberto

Alberto,
Indeed, I do not have a 'XmlValidator' folder in the '...bin\Custom Validation Engines' folder.
Can you point me in the right direction to create/populate this folder? Is that an install option?
Thanks,
Andy

Hi Andy,
you can trigger the on-demand download of the custom validators by manually validating an XML document using them; e.g. open an XML file, click on the arrow next to the green checkmark button in the toolbar, pick the .NET validator. A dialog will appear asking you to confirm the download of the package.

Hope this helps,
Alberto
