You can use a tool like Liquid XML Studio to load and validate the XSD, this will provide a graphical representation of the XSD and take you to the errors.
If you want do do this in code then:
- .Net you could load the XSD into an XmlSchemaSet and hook the ValidationEventHandler event to look out for errors. Once your schemas are loaded compiling the schema set will shake out an last errors.
- COM Load it into MSXML, the parsers not the best so it will output some spurious errors.
- Java with Xerces create a XMLSchemaFactory and use this to create a schema object, creating a validator from the schema will result in the schema itself being validated.

You haven't understood my question. I xsd (xml file) to validate another xml file, now want to validate the xsd file so I must create another xsd file. Now if I want to validate this xsd file I must create another xsd. You see the recursion? – Hunsu Feb 10 '15 at 10:31
