XML validation against XSD

Question

Is there any Free tool to visually validate XML against XSD files containing abstract elements?

(XMLSpy works great but needs a licence).

Answer 1

I found that I can both:

Inttellij IDEA https://www.jetbrains.com/idea/

and

XmlValidator 3.0 - 2011.10.24 http://brain2cpu.com

can do the job.

Answer 2

I used this tool, and works fine. XMLSpear

Some features:

• Full schema validation using DOM3 in Xerces 2.9.0
• Real-time validation against schema or DTD while editing
• XML catalog support (version 3.0
• Checks xsd schemas for errors, in exactly the same way as normal xml files
