Method Detail

nodeToString

@Nonnull
public static String nodeToString(@Nonnull
                                  Node node)

Converts a Node into a String using the DOM, level 3, Load/Save serializer.

Parameters:

node - the node to be written to a string

Returns:

the string representation of the node

nodeToString

@Nonnull
public static String nodeToString(@Nonnull
                                  Node node,
                                  @Nullable
                                  Map<String,Object> serializerParams)

Converts a Node into a String using the DOM, level 3, Load/Save serializer.

Parameters:

node - the node to be written to a string

serializerParams - parameters to pass to the DOMConfiguration of the serializer instance, obtained via LSSerializer.getDomConfig(). May be null.

Returns:

the string representation of the node

prettyPrintXML

@Nonnull
public static String prettyPrintXML(@Nonnull
                                    Node node)

Converts a Node into a String, using the DOM, level 3, Load/Save serializer. A serializer option of 'format-pretty-print=true' is used to produce the pretty-print formatting.

Parameters:

node - xml node to print

Returns:

pretty-printed xml

writeNode

public static void writeNode(@Nonnull
                             Node node,
                             @Nonnull
                             OutputStream output)

Writes a Node out to a Writer using the DOM, level 3, Load/Save serializer. The written content is encoded using the encoding specified in the writer configuration.

Parameters:

node - the node to write out

output - the output stream to write the XML to

writeNode

public static void writeNode(@Nonnull
                             Node node,
                             @Nonnull
                             OutputStream output,
                             @Nullable
                             Map<String,Object> serializerParams)

Writes a Node out to a Writer using the DOM, level 3, Load/Save serializer. The written content is encoded using the encoding specified in the writer configuration.

Parameters:

node - the node to write out

output - the output stream to write the XML to

serializerParams - parameters to pass to the DOMConfiguration of the serializer instance, obtained via LSSerializer.getDomConfig(). May be null.

getLSSerializer

@Nonnull
public static LSSerializer getLSSerializer(@Nonnull
                                           DOMImplementationLS domImplLS,
                                           @Nullable
                                           Map<String,Object> serializerParams)

Obtain a the DOM, level 3, Load/Save serializer LSSerializer instance from the given DOMImplementationLS instance.

The serializer instance will be configured with the parameters passed as the serializerParams argument. It will also be configured with an LSSerializerFilter that shows all nodes to the filter, and accepts all nodes shown.

Parameters:

domImplLS - the DOM Level 3 Load/Save implementation to use

serializerParams - parameters to pass to the DOMConfiguration of the serializer instance, obtained via LSSerializer.getDomConfig(). May be null.

Returns:

a new LSSerializer instance

getDOMImplementationLS

@Nonnull
public static DOMImplementationLS getDOMImplementationLS(@Nonnull
                                                         Node node)

Gets the DOM, level 3, Load/Store implementation associated with the given node.

Parameters:

node - the node, never null

Returns:

the Load/Store implementation, never null
