Class 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 Detail

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().

See Also:
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 Detail

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
