Class EntityResolver

java.lang.Object
  org.exist.validation.EntityResolver

All Implemented Interfaces:

org.apache.xerces.xni.parser.XMLEntityResolver

public class EntityResolver

extends java.lang.Object

implements org.apache.xerces.xni.parser.XMLEntityResolver

Specific grammar resolver for eXist. Currently supports XSD and DTD. XML Schemas and DTD grammars are stored in collections of the database: /db/system/grammar/xsd /db/system/grammar/dtd The XSD's are resolved automatically using xQuery. For DTD's (hey this is ancient stuff, these are no xml documents) separate data management is required. The details are stored in /db/system/grammar/dtd/catalog/xml Extra bonus: an xQuery generating a catalogus with DTD's and XSD's /db/system/grammar/xq/catalog.xq
