java.lang.Object org.apache.xml.resolver.tools.CatalogResolver
public class CatalogResolver
A SAX EntityResolver/JAXP URIResolver that uses catalogs.
This class implements both a SAX EntityResolver and a JAXP URIResolver.
This resolver understands OASIS TR9401 catalogs, XCatalogs, and the current working draft of the OASIS Entity Resolution Technical Committee specification.

public Catalog getCatalog()
public java.lang.String getResolvedEntity(java.lang.String publicId, java.lang.String systemId)
resolveEntity
method
for the SAX interface.
Presented with an optional public identifier and a system identifier, this function attempts to locate a mapping in the catalogs.
If such a mapping is found, it is returned. If no mapping is found, null is returned.
publicId
- The public identifier for the entity in question.
This may be null.systemId
- The system identifier for the entity in question.
XML requires a system identifier on all external entities, so this
value is always specified.
public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId)
resolveEntity
method
for the SAX interface.
Presented with an optional public identifier and a system identifier, this function attempts to locate a mapping in the catalogs.
If such a mapping is found, the resolver attempts to open the mapped value as an InputSource and return it. Exceptions are ignored and null is returned if the mapped value cannot be opened as an input source.
If no mapping is found (or an error occurs attempting to open the mapped value as an input source), null is returned and the system will use the specified system identifier as if no entityResolver was specified.
resolveEntity
in interface EntityResolver
publicId
- The public identifier for the entity in question.
This may be null.systemId
- The system identifier for the entity in question.
XML requires a system identifier on all external entities, so this
value is always specified.
InputSource
public Source resolve(java.lang.String href, java.lang.String base) throws TransformerException
resolve
in interface URIResolver
href
- An href attribute, which may be relative or absolute.base
- The base URI against which the first argument will be made
absolute if the absolute URI is required.
TransformerException
- if an error occurs when trying to
resolve the URI.
