Validating xml against dtd in java
In the context of Extensible Markup Language (XML), validation normally involves writing a detailed specification for the document's contents in any of several schema languages such as the World Wide Web Consortium (W3C) XML Schema Language (XSD), RELAX NG, Document Type Definitions (DTDs), and Schematron.
Sometimes validation is performed while parsing, sometimes immediately after.
The default response from a schema is to throw a to receive more detailed information about the document's problems.
For example, suppose you want to log all validation errors, but you don't want to stop processing when you encounter one.
A single implementation usually supports only a subset of the numerous languages and models.When you pass a URI identifying a particular schema language to that know how to process your schema language.Then, install your JAR in one of these four locations.The validator can create such type-augmented documents and write them onto a This procedure can't transform an arbitrary source into an arbitrary result.It doesn't work at all for stream sources and results.
