Class XmlValidatorFactory

java.lang.Object
  org.springframework.xml.validation.XmlValidatorFactory

public abstract class XmlValidatorFactory
extends Object

Factory for XmlValidator objects, being aware of JAXP 1.3 Validators, and JAXP 1.0 parsing capababilities. Mainly for internal use within the framework.

The goal of this class is to avoid runtime dependencies on JAXP 1.3 by using the best validation implementation that is available. Prefers JAXP 1.3 XmlValidator implementations to a custom, SAX-based implementation.

Since:

1.0.0
