DOMEntityResolver
Provides a way for applications to redirect
references to external entities.
Applications needing to implement customized handling for external
entities must implement this interface and register their implementation
by setting the entityResolver
property of the
DOMBuilder
.
The DOMBuilder
will then allow the application to intercept
any external entities (including the external DTD subset and external
parameter entities) before including them.
Many DOM applications will not need to implement this interface, but it
will be especially useful for applications that build XML documents from
databases or other specialized input sources, or for applications that
use URI types other than URIs. DOMEtityResolver
is based on
the SAX2 EntityResolver
interface.
See also the Document Object Model (DOM) Level 3 Abstract Schemas and Load and Save Specification.

Method Detail |
public DOMInputSource resolveEntity(java.lang.String publicId, java.lang.String systemId, java.lang.String baseURI) throws java.lang.Exception
DOMBuilder
will call this method before opening
any external entity except the top-level document entity (including
the external DTD subset, external entities referenced within the DTD,
and external entities referenced within the document element); the
application may request that the DOMBuilder
resolve the
entity itself, that it use an alternative URI, or that it use an
entirely different input source.
DOMBuilder
must
resolve it fully before reporting it to the application through this
interface. See issue #4. An alternative would be to pass the URI out
without resolving it, and to provide a base as an additional
parameter. SAX resolves URIs first, and does not provide a base.publicId
- The public identifier of the external entity being
referenced, or null
if none was supplied.systemId
- The system identifier, a URI reference , of the
external entity being referenced exactly as written in the source
(i.e. .baseURI
- The URI reference representing the base URI of the
resource being parsed, or null
if there is no base
URI.DOMInputSource
object describing the new input
source, or null
to request that the parser open a
regular URI connection to the system identifier.DOMSystemException
- Any DOMSystemException
, possibly wrapping another
exception.
