DOMSerializerImpl

public class DOMSerializerImpl extends Object implements LSSerializer, DOMConfiguration
EXPERIMENTAL: Implemenatation of DOM Level 3 org.w3c.ls.LSSerializer by delegating serialization calls to XMLSerializer. LSSerializer provides an API for serializing (writing) a DOM document out in an XML document. The XML data is written to an output stream. During serialization of XML data, namespace fixup is done when possible as defined in DOM Level 3 Core, Appendix B.

Constructors Summary
public DOMSerializerImpl()
Constructs a new LSSerializer. The constructor turns on the namespace support in XMLSerializer and initializes the following fields: fNSBinder, fLocalNSBinder, fSymbolTable, fEmptySymbol, fXmlSymbol, fXmlnsSymbol, fNamespaceCounter, fFeatures.

public booleanwrite(org.w3c.dom.Node node, org.w3c.dom.ls.LSOutput destination)
Serialize the specified node as described above in the general description of the LSSerializer interface. The output is written to the supplied LSOutput.
When writing to a LSOutput, the encoding is found by looking at the encoding information that is reachable through the LSOutput and the item to be written (or its owner document) in this order:
  1. LSOutput.encoding,
  2. Document.actualEncoding,
  3. Document.xmlEncoding.

If no encoding is reachable through the above properties, a default encoding of "UTF-8" will be used.
If the specified encoding is not supported an "unsupported-encoding" error is raised.
If no output is specified in the LSOutput, a "no-output-specified" error is raised.

param
node The node to serialize.
param
destination The destination for the serialized DOM.
return
Returns true if node was successfully serialized and false in case the node couldn't be serialized.

DOM L3 EXPERIMENTAL: Serialize the specified node as described above in the description of LSSerializer. The result of serializing the node is returned as a string. Writing a Document or Entity node produces a serialized form that is well formed XML. Writing other node types produces a fragment of text in a form that is not fully defined by this document, but that should be useful to a human for debugging or diagnostic purposes.

param
wnode The node to be written.
return
Returns the serialized data
exception
DOMException DOMSTRING_SIZE_ERR: The resulting string is too long to fit in a DOMString.
exception
LSException SERIALIZE_ERR: Unable to serialize the node. DOM applications should attach a DOMErrorHandler using the parameter "error-handler" to get details on error.

public booleanwriteToURI(org.w3c.dom.Node node, java.lang.String URI)
Serialize the specified node as described above in the general description of the LSSerializer interface. The output is written to the supplied URI.
When writing to a URI, the encoding is found by looking at the encoding information that is reachable through the item to be written (or its owner document) in this order:
  1. Document.inputEncoding,
  2. Document.xmlEncoding.

If no encoding is reachable through the above properties, a default encoding of "UTF-8" will be used.
If the specified encoding is not supported an "unsupported-encoding" error is raised.

param
node The node to serialize.
param
URI The URI to write to.
return
Returns true if node was successfully serialized and false in case the node couldn't be serialized.
