Class Serializer

public class Serializer
implements IDestination

A Serializer takes a tree representation of XML and turns it into lexical XML markup.

Note that this is serialization in the sense of the W3C XSLT and XQuery specifications. Unlike the class System.Xml.Serialization.XmlSerializer, this object does not serialize arbitrary CLI objects.

Property Detail

BaseUri

public Uri BaseUri {get; set; }

This property determines the base Uri of the constructed Serializer.

OutputFile

public string OutputFile {set; }

Specify the destination of the serialized output, in the form of a file name

Value:

The name of the file to receive the serialized output. This method sets the destination base URI to the URI corresponding to the name of the supplied file.

Throws:

SaxonApiException - Throws a SaxonApiException if it is not possible to create an output stream to write to this file, for example, if the filename is in a directory that does not exist.

OutputStream

public Stream OutputStream {set; }

Specify the destination of the serialized output, in the form of a Stream. This must be a stream that allows writing.

Saxon will not close the stream on completion; this is the caller's responsibility.

OutputWriter

public TextWriter OutputWriter {set; }

Specify the destination of the serialized output, in the form of a TextWriter.

Note that when writing to a TextWriter, character encoding is the responsibility of the TextWriter, not the Serializer. This means that the encoding requested in the output properties is ignored; it also means that characters that cannot be represented in the target encoding will use whatever fallback representation the TextWriter defines, rather than being represented as XML character references.

Saxon will not close the TextWriter on completion; this is the caller's responsibility.

Processor

public Processor Processor {get; }

The Processor from which this Serializer was created.

UnderlyingDestination

public net.sf.saxon.s9api.Destination UnderlyingDestination {get; }

The underlying Saxon.Hej.s9api.Destination object in the Saxon implementation

This property provides access to internal methods in the Saxon engine that are not specifically exposed in the .NET API. In general these methods should be considered to be less stable than the classes in the Saxon.Api namespace.

The internal methods follow Java naming conventions rather than .NET conventions.

Information about the returned net.sf.saxon.s9api.Destination object (and the objects it provides access to) is included in the Saxon JavaDoc documentation.

Value:

The underlying Destination object

Method Detail

Close

public void Close()

Close any resources associated with this destination. Note that this does not close any user-supplied OutputStream or Writer; those must be closed explicitly by the calling application.

GetCharacterMap

public IDictionary<int, string> GetCharacterMap(QName name)

Get the character map with a given name

Parameters:

name - The name of the character map, as a QName

Returns:

A dictionary that maps integer Unicode codepoint values to strings

OnClose

public void OnClose(Action action)

Define an action to be performed when writing to the Destination is complete.

Parameters:

action - The action to be performed.

SerializeXdmNode

public void SerializeXdmNode(XdmNode node)

Serialize an XdmNode to the selected output destination using this serializer.

since 9.8

Parameters:

node - The node to be serialized

SerializeXdmValue

public void SerializeXdmValue(XdmValue value)

Serialize an arbitrary XdmValue to the selected output destination using this serializer. The supplied sequence is first wrapped in a document node according to the rules given in section 2 (Sequence Normalization) of the XSLT/XQuery serialization specification; the resulting document node is then serialized using the serialization parameters defined in this serializer. A call on this method will close the writer or output stream internally.

since 9.8

Parameters:

value -  The value to be serialized

SetCharacterMap

public void SetCharacterMap(QName name,
IDictionary<int, string> charMap)

Set a character map to be used

Note that the character map is used by the serializer only if the USE_CHARACTER_MAPS output property includes the name of this character map.

Parameters:

name - the name of the character map
charMap - the content of the character map, supplied as a dictionary that maps integer Unicode codepoint values to strings

SetOutputProperty

public void SetOutputProperty(QName name,
string value)

Set a serialization property

In the case of XSLT, properties set within the serializer override any properties set in xsl:output declarations in the stylesheet. Similarly, with XQuery, they override any properties set in the Query prolog using declare option output.

Parameters:

name - The name of the serialization property to be set
value - The value to be set for the serialization property. May be null to unset the property (that is, to set it back to the default value).

Example:

Serializer qout = processor.NewSerializer(); qout.SetOutputProperty(Serializer.METHOD, "xml"); qout.SetOutputProperty(Serializer.INDENT, "yes"); qout.SetOutputProperty(Serializer.SAXON_INDENT_SPACES, "1");
