Parameters:
inputStream - specifies the InputStream to read from
Returns:
the new XMLDocument loaded
Throws:
java.io.IOException - for stream exceptions.

Parameters:
inputSource - specifies the Source to read from
locationURI - specifies the URI of the document for relative schema locations
options - implementation-specific options.
Returns:
the new XMLDocument loaded
Throws:

save

java.lang.String save(DataObject dataObject,
                      java.lang.String rootElementURI,
                      java.lang.String rootElementName)
Returns the DataObject saved as an XML document with the specified root element. Same as StringWriter stringWriter = new StringWriter(); save(createDocument(dataObject, rootElementURI, rootElementName), stringWriter, null); stringWriter.toString();

Parameters:

rootElementURI - the Target Namespace URI of the root XML element
rootElementName - the Name of the root XML element
Returns:
the saved XML document as a string
Throws:
java.lang.IllegalArgumentException - if the dataObject tree is not closed or has no container.

Does not perform validation to ensure compliance with an XSD.

Parameters:
xmlDocument - specifies XMLDocument to be saved
outputStream - specifies the OutputStream to write to.
options - implementation-specific options.
Throws:
java.io.IOException - for stream exceptions.

Serializes an XMLDocument as an XML document into the outputWriter. If the DataObject's Type was defined by an XSD, the serialization will follow the XSD. Otherwise the serialization will follow the format as if an XSD were generated as defined by the SDO specification. The OutputStream will be flushed after writing. Does not perform validation to ensure compliance with an XSD.

Parameters:
xmlDocument - specifies XMLDocument to be saved
outputWriter - specifies the Writer to write to.
options - implementation-specific options.
Throws:
java.io.IOException - for stream exceptions.

outputResult - specifies Result to be saved
options - implementation-specific options.
Throws:
java.io.IOException - for stream exceptions.
java.lang.IllegalArgumentException - if the dataObject tree is not closed or has no container.

XMLDocument createDocument(DataObject dataObject,
                           java.lang.String rootElementURI,
                           java.lang.String rootElementName)
Creates an XMLDocument with the specified XML rootElement for the DataObject.
