Package javax.xml.transform.dom

Class DOMSource

java.lang.Object

javax.xml.transform.dom.DOMSource

All Implemented Interfaces:

Source

public class DOMSource
extends Object
implements Source

Acts as a holder for a transformation Source tree in the form of a Document Object Model (DOM) tree.

Note that XSLT requires namespace support. Attempting to transform a DOM that was not contructed with a namespace-aware parser may result in errors. Parsers can be made namespace aware by calling DocumentBuilderFactory.setNamespaceAware(boolean awareness).

Since:

1.4

Constructor	Description
DOMSource()	Zero-argument default constructor.
DOMSource(Node n)	Create a new input source with a DOM node.
DOMSource(Node node, String systemID)	Create a new input source with a DOM node, and with the system ID also passed in as the base URI.

void	setNode(Node node)	Set the node that will represents a Source DOM tree.
void	setSystemId(String systemID)	Set the base ID (URL or system ID) from where URLs will be resolved.

Constructor Details

DOMSource

public DOMSource()

Zero-argument default constructor. If this constructor is used, and no DOM source is set using setNode(Node node) , then the Transformer will create an empty source Document using DocumentBuilder.newDocument().

• Transformer.transform(Source xmlSource, Result outputTarget)

DOMSource

public DOMSource(Node n)

Create a new input source with a DOM node. The operation will be applied to the subtree rooted at this node. In XSLT, a "/" pattern still means the root of the tree (not the subtree), and the evaluation of global variables and parameters is done from the root node also.

Parameters:

n - The DOM node that will contain the Source tree.

DOMSource

public DOMSource(Node node,
 String systemID)

Create a new input source with a DOM node, and with the system ID also passed in as the base URI.

Parameters:

node - The DOM node that will contain the Source tree.

systemID - Specifies the base URI associated with node.

Method Details

setNode

public void setNode(Node node)

Set the node that will represents a Source DOM tree.

Parameters:

node - The node that is to be transformed.

getNode

public Node getNode()

Get the node that represents a Source DOM tree.

Returns:

The node that is to be transformed.

setSystemId

public void setSystemId(String systemID)

Set the base ID (URL or system ID) from where URLs will be resolved.

Specified by:

setSystemId in interface Source

Parameters:

systemID - Base URL for this DOM tree.

getSystemId

public String getSystemId()

Get the base ID (URL or system ID) from where URLs will be resolved.

Specified by:

getSystemId in interface Source

Returns:

Base URL for this DOM tree.

isEmpty

public boolean isEmpty()

Indicates whether the DOMSource object is empty. Empty is defined as follows:

• if the system identifier and node are null;
• if the system identifier is null, and the node has no child nodes.

Specified by:

isEmpty in interface Source

Returns:

true if the DOMSource object is empty, false otherwise
