Howto validate xml schema?

[Alan Mc Kernan]

Guys, I want to programatically validate xml schema files.. can someone point me in the right direction. I dont want to validate xml files against a schema, but moreso to validate the schema itself.

Cheers

Isn't that supposed to be the beauty of schemas versus DTDs? If you know how to validate an xml document against a schema, do that to your schema document: validate myschema.xsd against schema http://www.w3.org/2001/XMLSchema.xsd

Write a schema to validate a schema, since a schema is an XML?

Hi Jeff,

I think Alan wanted to validate a schema rather than the actual XML data file. But if I'm mistaken, Jeff's way is correct.

Hrm, yeah that makes sense.

But what about sub files that the XSD imports/links to?

Basically Ill have a directory with a tree of XSD's, some have common elements which are contained in their own XSD and then the top level XSD's import those.

So basically I want to programically (or by some automated means) ensure that they are all valid. i.e there may be cases where the command element XSD's are missing.. or not valid for some reason.

This technique.. semi works. It will validate that the XSD is well formed, but when I remove an import, which is used in the schema, it still passes with no problems.

Anyone any ideas?
