Answer 1

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: http://stackoverflow.com/questions/74879/any-tools-to-generate-an-xsd-schema-from-an-xml-instance-document

Answer 2

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