Deprecated

As of JDK 9, Xerces 2.9.0, Xerces DOM L3 Serializer implementation is replaced by that of Xalan. Main class com.sun.org.apache.xml.internal.serialize.DOMSerializerImpl is replaced by com.sun.org.apache.xml.internal.serializer.dom3.LSSerializerImpl.

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 serialize(Document) or by using DOM Level 3 org.w3c.dom.ls.LSSerializer and serializing with org.w3c.dom.ls.LSSerializer#write, org.w3c.dom.ls.LSSerializer#writeToString.

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 org.xml.sax.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.

Doc from com.sun.org.apache.xml.internal.serialize.Serializer.setOutputFormat.

References Deprecated

OutputFormat is deprecated or references (maybe indirectly) at least one deprecated element.

See corresponding docs for further information.

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.

startDocumentback to summary
protected void startDocument(String rootTagName) throws IOException

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 (_started), will serialize the document type declaration, and will serialize all pre-root comments and PIs that were accumulated in the document (see serializePreRoot). Pre-root will be serialized even if this is not the first root element of the document.

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

Implements org.xml.sax.ContentHandler.startElement.

Doc from org.xml.sax.ContentHandler.startElement.

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.

Exceptions
SAXException:
any SAX exception, possibly wrapping another exception
