public class TextSerializer
extends BaseMarkupSerializer

Implements a text serializer supporting both DOM and SAX 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. DOM serializing is done by calling `BaseMarkupSerializer.serialize(org.w3c.dom.Element)` and SAX serializing is done by firing 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 at the end of serializing (either DOM or SAX's `DocumentHandler.endDocument()`.

Constructor Detail

### TextSerializer

    public TextSerializer()

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

Method Detail

### setOutputFormat

    public void setOutputFormat(OutputFormat format)

  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.
  Overrides:
    `setOutputFormat` in class `BaseMarkupSerializer`
  Following copied from interface: `org.apache.xml.serialize.Serializer`
  Parameters:
    `format` - The output format to use

### startElement

    public void startElement(java.lang.String namespaceURI,
                             java.lang.String localName,
                             java.lang.String rawName,
                             org.xml.sax.Attributes attrs)
                      throws org.xml.sax.SAXException

### endElement

    public void endElement(java.lang.String namespaceURI,
                           java.lang.String localName,
                           java.lang.String rawName)
                    throws org.xml.sax.SAXException

### startElement

    public void startElement(java.lang.String tagName,
                             org.xml.sax.AttributeList attrs)
                      throws org.xml.sax.SAXException

### endElement

    public void endElement(java.lang.String tagName)
                    throws org.xml.sax.SAXException

### endElementIO

    public void endElementIO(java.lang.String tagName)
                      throws java.io.IOException

### processingInstructionIO

    public void processingInstructionIO(java.lang.String target,
                                        java.lang.String code)
                                 throws java.io.IOException

  Overrides:
    `processingInstructionIO` in class `BaseMarkupSerializer`

### comment

    public void comment(java.lang.String text)

  Overrides:
    `comment` in class `BaseMarkupSerializer`

### comment

    public void comment(char[] chars,
                        int start,
                        int length)

  Overrides:
    `comment` in class `BaseMarkupSerializer`

### characters

    public void characters(char[] chars,
                           int start,
                           int length)
                    throws org.xml.sax.SAXException

  Overrides:
    `characters` in class `BaseMarkupSerializer`

### characters

    protected void characters(java.lang.String text,
                              boolean unescaped)
                       throws java.io.IOException

### startDocument

    protected void startDocument(java.lang.String rootTagName)
                          throws java.io.IOException

  Called to serialize the document's DOCTYPE by the root element.

  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.

### serializeElement

    protected void serializeElement(org.w3c.dom.Element elem)
                             throws java.io.IOException

  Called to serialize a DOM element. Equivalent to calling `startElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes)`, `endElement(java.lang.String, java.lang.String, java.lang.String)` and serializing everything inbetween, but better optimized.
  Overrides:
    `serializeElement` in class `BaseMarkupSerializer`
  Following copied from class: `org.apache.xml.serialize.BaseMarkupSerializer`
  Parameters:
    `elem` - The element to serialize
  Throws:
    `java.io.IOException` - An I/O exception occured while serializing

### serializeNode

    protected void serializeNode(org.w3c.dom.Node node)
                          throws java.io.IOException

  Serialize the DOM node. This method is unique to the Text serializer.
  Overrides:
    `serializeNode` in class `BaseMarkupSerializer`
  Parameters:
    `node` - The node to serialize

### content

    protected ElementState content()

  Description copied from class: `BaseMarkupSerializer`
  Must be called by a method about to print any type of content. If the element was just opened, the opening tag is closed and will be matched to a closing tag. Returns the current element state with `empty` and `afterElement` set to false.
  Overrides:
    `content` in class `BaseMarkupSerializer`
  Following copied from class: `org.apache.xml.serialize.BaseMarkupSerializer`
  Returns:
    The current element state
  Throws:
    `java.io.IOException` - An I/O exception occured while serializing

### getEntityRef

    protected java.lang.String getEntityRef(int ch)

  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 `"&amp;"`.
  Overrides:
    `getEntityRef` in class `BaseMarkupSerializer`
  Following copied from class: `org.apache.xml.serialize.BaseMarkupSerializer`
  Parameters:
    `ch` - Character value
  Returns:
    Character entity name, or null
