parseDTD
public DTDdocument parseDTD(java.io.Reader reader) throws DTDException
Parses text of a DTD document and returns corresponding DTD document object. It is left to constructor of the reader to set up character encoding correctly. This means that method read of the reader is used to get next character, assuming it returns appropriate values.- Parameters:
reader
- input char stream reader. It is recommended to use classjava.io.InputStreamReader
as a reader, which allows to set desired character encoding.- Returns:
- DTD document object corresponding to the input text of a DTD document.
- Throws:
DTDException
- if the DTD document is syntactically or semanticly not correct.
-

public Schema convertDTDObjectToSchemaObject(DTDdocument dtd, java.lang.String targetNamespace, java.util.Map nameSpaceMap) throws DTDException, SchemaException
Convert DTD document object to corresponding Schema object.- Parameters:
dtd
- input XML DTD document object.nameSpacePrefix
-nameSpace
-- Returns:
- corresponding XML Schema object.
- Throws:
DTDException
- if the input DTD document is malformed.SchemaException
- if Schema object can not be created.
-
convertDTDElementToSchemaElement
public ElementDecl convertDTDElementToSchemaElement(Element dtdElement, Schema schema) throws DTDException, SchemaException
Convert DTD Element declaration to Schema Element Declaration.- Parameters:
dtdElement
- DTD Element declaration.schema
- Schema owning Element declaration.- Returns:
- corresponding Schema Element declaration.
- Throws:
DTDException
- if the input DTD Element Declaration is malformed.SchemaException
- if unable to construct returnElementDecl
object from the input DTDElement
object.
-
convertContentParticle
public Particle convertContentParticle(ContentParticle dtdContent, Schema schema) throws DTDException, SchemaException
Method to convertContentParticle
object, used to implement element content in the DTD object model, to the corresponding object in the Schema object model: eitherGroup
orElementDecl
.- Parameters:
dtdContent
- inputContentParticle
object.- Returns:
- object returned is an instance of either
Group
class orElementDecl
class. - Throws:
DTDException
- if the input ContentParticle is malformed.SchemaException
