Browser plugin for XSD Validation of an xml document

Question

What I am looking for is something similar to this plug-in for FireFox 0.8 to 1.0.x. I want a plug-in that will do XSD validation against an xml document currently loaded into the browser.

Answer 1

Firefox does this on its own, I think. I've loaded non-validating XML docs and it told me what the error was and where (I used it at work to debug schema problems). I do, however, have the Web Developer add-on installed...so that might be providing the capability. The XML doc needs to correctly specify the namespace/schema location, of course.

The add-on you linked to appears to validate the schema itself, not an XML instance document against a schema, which is a separate process. I don't think FF will do this.

Answer 2

Maybe the extension you pointed would work in recent versions of Firefox. Try to download the extension, change the maxVersion in its manifest and install it in Firefox.
