Class XMLSerializer

java.lang.Object
  |
        |

Implements an XML serializer supporting both DOM and SAX pretty

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. DOM serializing is done SAX events and using the serializer as a document handler.

If an I/O exception occurs while serializing, the serializer will not throw an exception directly, but only throw it

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 Detail 

public XMLSerializer()
Constructs a new serializer. The serializer cannot be used without first.


Constructs a new serializer. The serializer cannot be used without
 first.





public XMLSerializer(java.io.Writer writer,



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









public XMLSerializer(java.io.OutputStream output,



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 Detail





setOutputFormat



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.






Parameters:
format - The output format to use








startElement

public void startElement(java.lang.String namespaceURI,
                         java.lang.String localName,
                         java.lang.String rawName,



Receive notification of the beginning of an element.

 
The Parser will invoke this method at the beginning of every
 element in the XML document; there will be a corresponding
 (even when the element is empty). All of the element's content will be
 reported, in order, before the corresponding endElement
 event.


 
This event allows up to three name components for each
 element:


 
    
 
  1. the Namespace URI;
    2. 
 
  2. the local name; and
    3. 
 
  3. the qualified (prefixed) name.
    4. 
 


 
Any or all of these may be provided, depending on the
 properties:


 
    
 
  • the Namespace URI and local name are required when 
 the namespaces property is true (the default), and are
 optional when the namespaces property is false (if one is
 specified, both must be);
    • 
 
  • the qualified name is required when the namespace-prefixes property
 is true, and is optional when the namespace-prefixes property
 is false (the default).
    • 
 


 
Note that the attribute list provided will contain only
 attributes with explicit values (specified or defaulted):
 #IMPLIED attributes will be omitted.  The attribute list
 will contain attributes used for Namespace declarations
 property is true (it is false by default, and support for a 



Parameters:
uri - The Namespace URI, or the empty string if the
        element has no Namespace URI or if Namespace
        processing is not being performed.
localName - The local name (without prefix), or the
        empty string if Namespace processing is not being
        performed.
qName - The qualified name (with prefix), or the
        empty string if qualified names are not available.
atts - The attributes attached to the element.  If
        there are no attributes, it shall be an empty









endElement


public void endElement(java.lang.String namespaceURI,
                       java.lang.String localName,
                       java.lang.String rawName)




Receive notification of the end of an element.

 
The SAX parser will invoke this method at the end of every
 element in the XML document; there will be a corresponding
 event (even when the element is empty).





Parameters:
uri - The Namespace URI, or the empty string if the
        element has no Namespace URI or if Namespace
        processing is not being performed.
localName - The local name (without prefix), or the
        empty string if Namespace processing is not being
        performed.
qName - The qualified XML 1.0 name (with prefix), or the
            wrapping another exception.








startElement

public void startElement(java.lang.String tagName,



Receive notification of the beginning of an element.

 
The Parser will invoke this method at the beginning of every
 element in the XML document; there will be a corresponding
 endElement() event for every startElement() event (even when the
 element is empty). All of the element's content will be
 reported, in order, before the corresponding endElement()
 event.


 
If the element name has a namespace prefix, the prefix will
 still be attached.  Note that the attribute list provided will
 contain only attributes with explicit values (specified or











endElement


public void endElement(java.lang.String tagName)




Receive notification of the end of an element.

 
The SAX parser will invoke this method at the end of every
 element in the XML document; there will be a corresponding
 startElement() event for every endElement() event (even when the
 element is empty).


 
If the element name has a namespace prefix, the prefix will


            wrapping another exception.










startDocument


protected void startDocument(java.lang.String rootTagName)




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.
 

 will serialize the document type declaration, and will serialize all
 pre-root comments and PIs that were accumulated in the document
 this is not the first root element of the document.






serializeElement


protected void serializeElement(Element elem)



 inbetween, but better optimized.






Parameters:
elem - The element to serialize










getEntityRef


protected java.lang.String getEntityRef(char ch)




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






Parameters:
ch - Character value
Returns:
Character entity name, or null
