Class XMLSerializer

java.lang.Object

org.apache.xml.serialize.BaseMarkupSerializer

org.apache.xml.serialize.XMLSerializer

All Implemented Interfaces:

DOMSerializer, Serializer, ContentHandler, DocumentHandler, DTDHandler, DeclHandler, LexicalHandler

Direct Known Subclasses:

XML11Serializer

public class XMLSerializer
extends BaseMarkupSerializer

Deprecated.

This class was deprecated in Xerces 2.9.0. It is recommended that new applications use the DOM Level 3 LSSerializer or JAXP's Transformation API for XML (TrAX) for serializing XML. See the Xerces documentation for more information.

Implements an XML serializer supporting both DOM and SAX pretty serializing. For usage instructions see Serializer.

If an output stream is used, the encoding is taken from the output format (defaults to UTF-8). If a writer is used, make sure the writer uses the same encoding (if applies) as specified in the output format.

The serializer supports both DOM and SAX. SAX serializing is done by firing SAX events and using the serializer as a document handler. DOM serializing is done by calling BaseMarkupSerializer.serialize(Document) or by using DOM Level 3 LSSerializer and serializing with LSSerializer.write(Node, LSOutput), LSSerializer.writeToString(Node).

If an I/O exception occurs while serializing, the serializer will not throw an exception directly, but only throw it at the end of serializing (either DOM or SAX's DocumentHandler.endDocument().

For elements that are not specified as whitespace preserving, the serializer will potentially break long text lines at space boundaries, indent lines, and serialize elements on separate lines. Line terminators will be regarded as spaces, and spaces at beginning of line will be stripped.

Constructor Details

XMLSerializer

public XMLSerializer()

Deprecated.

Constructs a new serializer. The serializer cannot be used without calling BaseMarkupSerializer.setOutputCharStream(Writer) or BaseMarkupSerializer.setOutputByteStream(OutputStream) first.

XMLSerializer

public XMLSerializer(OutputFormat format)

Deprecated.

Constructs a new serializer. The serializer cannot be used without calling BaseMarkupSerializer.setOutputCharStream(Writer) or BaseMarkupSerializer.setOutputByteStream(OutputStream) first.

XMLSerializer

public XMLSerializer(Writer writer,
 OutputFormat format)

Deprecated.

Constructs a new serializer that writes to the specified writer using the specified output format. If format is null, will use a default output format.

Parameters:

writer - The writer to use

format - The output format to use, null for the default

XMLSerializer

public XMLSerializer(OutputStream output,
 OutputFormat format)

Deprecated.

Constructs a new serializer that writes to the specified output stream using the specified output format. If format is null, will use a default output format.

Parameters:

output - The output stream to use

format - The output format to use, null for the default

Method Details

setOutputFormat

public void setOutputFormat(OutputFormat format)

Deprecated.

Description copied from interface: Serializer

Specifies an output format for this serializer. It the serializer has already been associated with an output format, it will switch to the new format. This method should not be called while the serializer is in the process of serializing a document.

Specified by:

setOutputFormat in interface Serializer

Overrides:

setOutputFormat in class BaseMarkupSerializer

Parameters:

format - The output format to use

setNamespaces

public void setNamespaces(boolean namespaces)

Deprecated.

This methods turns on namespace fixup algorithm during DOM serialization.

Parameters:

namespaces -

startElement

public void startElement(String namespaceURI,
 String localName,
 String rawName,
 Attributes attrs)
                  throws SAXException

Deprecated.

Throws:

SAXException

endElement

public void endElement(String namespaceURI,
 String localName,
 String rawName)
                throws SAXException

Deprecated.

Throws:

SAXException

endElementIO

public void endElementIO(String namespaceURI,
 String localName,
 String rawName)
                  throws IOException

Deprecated.

Throws:

IOException

startElement

public void startElement(String tagName,
 AttributeList attrs)
                  throws SAXException

Deprecated.

Throws:

SAXException

endElement

public void endElement(String tagName)
                throws SAXException

Deprecated.

Throws:

SAXException

startDocument

protected void startDocument(String rootTagName)
                      throws IOException

Deprecated.

Called to serialize the document's DOCTYPE by the root element. The document type declaration must name the root element, but the root element is only known when that element is serialized, and not at the start of the document.

This method will check if it has not been called before (BaseMarkupSerializer._started), will serialize the document type declaration, and will serialize all pre-root comments and PIs that were accumulated in the document (see BaseMarkupSerializer.serializePreRoot()). Pre-root will be serialized even if this is not the first root element of the document.

Throws:

IOException

serializeElement

protected void serializeElement(Element elem)
                         throws IOException

Deprecated.

Called to serialize a DOM element. Equivalent to calling startElement(String, String, String, Attributes), endElement(String, String, String) and serializing everything inbetween, but better optimized.

Specified by:

serializeElement in class BaseMarkupSerializer

Parameters:

elem - The element to serialize

Throws:

IOException - An I/O exception occured while serializing

getEntityRef

protected String getEntityRef(int ch)

Deprecated.

Description copied from class: BaseMarkupSerializer

Returns the suitable entity reference for this character value, or null if no such entity exists. Calling this method with '&' will return "&".

Specified by:

getEntityRef in class BaseMarkupSerializer

Parameters:

ch - Character value

Returns:

Character entity name, or null

printEscaped

protected void printEscaped(String source)
                     throws IOException

Deprecated.

Description copied from class: BaseMarkupSerializer

Escapes a string so it may be printed as text content or attribute value. Non printable characters are escaped using character references. Where the format specifies a deault entity reference, that reference is used (e.g. <).

Overrides:

printEscaped in class BaseMarkupSerializer

Parameters:

source - The string to escape

Throws:

IOException

printXMLChar

protected void printXMLChar(int ch)
                     throws IOException

Deprecated.

print text data

Throws:

IOException

protected void printText(String text,
 boolean preserveSpace,
 boolean unescaped)
                  throws IOException

Deprecated.

Overrides:

printText in class BaseMarkupSerializer

Throws:

IOException

printText

protected void printText(char[] chars,
 int start,
 int length,
 boolean preserveSpace,
 boolean unescaped)
                  throws IOException

Deprecated.

Description copied from class: BaseMarkupSerializer

Called to print additional text with whitespace handling. If spaces are preserved, the text is printed as if by calling BaseMarkupSerializer.printText(String,boolean,boolean) with a call to Printer.breakLine() for each new line. If spaces are not preserved, the text is broken at space boundaries if longer than the line width; Multiple spaces are printed as such, but spaces at beginning of line are removed.

Overrides:

printText in class BaseMarkupSerializer

Parameters:

chars - The text to print

start - The start offset

length - The number of characters

preserveSpace - Space preserving flag

unescaped - Print unescaped

IOException

Deprecated.

DOM Level 3: Check a node to determine if it contains unbound namespace prefixes.

Overrides:

checkUnboundNamespacePrefixedNode in class BaseMarkupSerializer

Parameters:

node - The node to check for unbound namespace prefices

Throws:

IOException
