public class StandardEntityResolver extends java.lang.Object implements org.xml.sax.EntityResolver
|Constructor and Description|
|Modifier and Type||Method and Description|
Get the source from a given file.
Get a resource from the classpath.
Register a DTD or other entity to be resolved by this entity resolver
Allow the application to resolve external entities.
Set configuration details.
public Configuration config
public StandardEntityResolver(Configuration config)
public static void register(java.lang.String publicId, java.lang.String systemId, java.lang.String fileName)
publicId- the public identifier of the DTD or entity
systemId- the system identifier of the DTD or entity. For domains that are known to redirect http: to https:, either scheme is accepted.
fileName- the fileName of the Saxon local copy of the resource, relative to the data directory in the JAR file
public void setConfiguration(Configuration config)
config- the Saxon configuration
public org.xml.sax.InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId) throws org.xml.sax.SAXException
The parser will call this method before opening any external entity except the top-level document entity. Such entities include the external DTD subset and external parameter entities referenced within the DTD (in either case, only if the parser reads external parameter entities), and external general entities referenced within the document element (if the parser reads external general entities). The application may request that the parser locate the entity itself, that it use an alternative URI, or that it use data provided by the application (as a character or byte input stream).
Application writers can use this method to redirect external system identifiers to secure and/or local URIs, to look up public identifiers in a catalogue, or to read an entity from a database or other input source (including, for example, a dialog box). Neither XML nor SAX specifies a preferred policy for using public or system IDs to resolve resources. However, SAX specifies how to interpret any InputSource returned by this method, and that if none is returned, then the system ID will be dereferenced as a URL.
If the system identifier is a URL, the SAX parser must resolve it fully before reporting it to the application.
publicId- The public identifier of the external entity being referenced, or null if none was supplied.
systemId- The system identifier of the external entity being referenced.
org.xml.sax.SAXException- Any SAX exception, possibly wrapping another exception.
public static org.xml.sax.InputSource fetch(java.lang.String filename, Configuration config)
filename- the name of the file
config- the Saxon Configuration
protected org.xml.sax.InputSource getResource(java.lang.String resourceName, Configuration config)
resourceName- the resource to be fetched from the classpath
config- the Saxon Configuration object
