i am working with java6...

One possibility is to create an XSLT transform that converts the homegrown schema document into a standard such as XML Schema or Relax NG.

Check out Package javax.xml.validation , as of Java 5 the API supports validation for custom schema.

The SchemaFactory object has a method newSchema that will take a file and create a schema from it that can be validated against.

Edit: If you need to convert your XML file to a schema look at this question: Any tools to generate an XSD schema from an XML instance document?
