      org.apache.xml.serialize.BaseMarkupSerializer
          org.apache.xml.serialize.TextSerializer

All Implemented Interfaces:
  DOMSerializer, Serializer, org.xml.sax.ContentHandler, org.xml.sax.DocumentHandler, org.xml.sax.DTDHandler, org.xml.sax.ext.DeclHandler, org.xml.sax.ext.LexicalHandler

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 and HTML. See the Xerces documentation for more information.

    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()

  Deprecated.
  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)

  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

### 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

  Deprecated.
  Description copied from interface: `org.xml.sax.ContentHandler`
  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.

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

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

  Any or all of these may be provided, depending on the values of the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes 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 (xmlns* attributes) only if the `http://xml.org/sax/features/namespace-prefixes` property is true (it is false by default, and support for a true value is optional).

  Like `characters()`, attribute values may have characters that need more than one `char` value.

  Parameters:
    `namespaceURI` - 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
    `rawName` - the qualified name (with prefix), or the empty string if qualified names are not available
    `attrs` - the attributes attached to the element. If there are no attributes, it shall be an empty Attributes object. The value of this object after startElement returns is undefined
  Throws:
    `org.xml.sax.SAXException` - any SAX exception, possibly wrapping another exception
  See Also:
    `ContentHandler.endElement(java.lang.String, java.lang.String, java.lang.String)`, `Attributes`, `AttributesImpl`

### endElement

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

  Deprecated.
  Description copied from interface: `org.xml.sax.ContentHandler`
  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).

  For information on the names, see startElement.

  Parameters:
    `namespaceURI` - 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
    `rawName` - the qualified XML name (with prefix), or the empty string if qualified names are not available
  Throws:
    `org.xml.sax.SAXException` - any SAX exception, possibly wrapping another exception

### startElement

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

  Deprecated.
  Description copied from interface: `org.xml.sax.DocumentHandler`
  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 defaulted): #IMPLIED attributes will be omitted.

  Parameters:
    `tagName` - The element type name.
    `attrs` - The attributes attached to the element, if any.
  Throws:
    `org.xml.sax.SAXException` - Any SAX exception, possibly wrapping another exception.

  Deprecated.
  Description copied from interface: `org.xml.sax.DocumentHandler`
  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 still be attached to the name.

  Parameters:

    `comment` in class `BaseMarkupSerializer`

### comment

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

  Deprecated.
  Description copied from interface: `org.xml.sax.ext.LexicalHandler`
  Report an XML comment anywhere in the document.

  This callback will be used for comments inside or outside the document element, including comments in the external DTD subset (if read). Comments in the DTD must be properly nested inside start/endDTD and start/endEntity events (if used).

  Specified by:
    `comment` in interface `org.xml.sax.ext.LexicalHandler`
  Overrides:
    `comment` in class `BaseMarkupSerializer`
  Parameters:
    `chars` - An array holding the characters in the comment.
    `start` - The starting position in the array.
    `length` - The number of characters to use from the array.

### characters

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

  Deprecated.
  Description copied from interface: `org.xml.sax.ContentHandler`
  Receive notification of character data.

  The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.

  The application must not attempt to read from the array outside of the specified range.

  Individual characters may consist of more than one Java `char` value. There are two important cases where this happens, because characters can't be represented in just sixteen bits. In one case, characters are represented in a Surrogate Pair, using two special Unicode values. Such characters are in the so-called "Astral Planes", with a code point above U+FFFF. A second case involves composite characters, such as a base character combining with one or more accent characters.

  Your code should not assume that algorithms using `char`-at-a-time idioms will be working in character units; in some cases they will split characters. This is relevant wherever XML permits arbitrary characters, such as attribute values, processing instruction data, and comments as well as in data reported from this method. It's also generally relevant whenever Java code manipulates internationalized text; the issue isn't unique to XML.

  Note that some parsers will report whitespace in element content using the `ignorableWhitespace` method rather than this one (validating parsers must do so).

  Specified by:
    `characters` in interface `org.xml.sax.ContentHandler`
  Specified by:
    `characters` in interface `org.xml.sax.DocumentHandler`
  Overrides:
    `characters` in class `BaseMarkupSerializer`
  Parameters:
    `chars` - the characters from the XML document
    `start` - the start position in the array
    `length` - the number of characters to read from the array
  Throws:
    `org.xml.sax.SAXException` - Any SAX exception, possibly wrapping another exception.
  See Also:
    `ContentHandler.ignorableWhitespace(char[], int, int)`, `Locator`

### characters

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

  Deprecated.
  Throws:
    `java.io.IOException`

### startDocument

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

  Deprecated.
  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.

  Throws:
    `java.io.IOException`

### serializeElement

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

  Deprecated.
  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.

  Specified by:
    `serializeElement` in class `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

  Deprecated.
  Serialize the DOM node. This method is unique to the Text serializer.

  Overrides:
    `serializeNode` in class `BaseMarkupSerializer`
  Parameters:
    `node` - The node to serialize
  Throws:
    `java.io.IOException` - An I/O exception occured while serializing
  See Also:
    `BaseMarkupSerializer.serializeElement(org.w3c.dom.Element)`

### content

    protected ElementState content()

  Deprecated.
  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`
  Returns:
    The current element state

### getEntityRef

    protected java.lang.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 `"&amp;"`.

  Specified by:
    `getEntityRef` in class `BaseMarkupSerializer`
  Parameters:
    `ch` - Character value
  Returns:
    Character entity name, or null
