# Class DOMStructure

java.lang.Object
javax.xml.crypto.dom.DOMStructure

All Implemented Interfaces:
  `XMLStructure`

public class DOMStructure extends Object implements XMLStructure
A DOM-specific `XMLStructure`. The purpose of this class is to allow a DOM node to be used to represent extensible content (any elements or mixed content) in XML Signature structures.

If a sequence of nodes is needed, the node contained in the `DOMStructure` is the first node of the sequence and successive nodes can be accessed by invoking `Node.getNextSibling()`.

If the owner document of the `DOMStructure` is different than the target document of an `XMLSignature`, the `XMLSignature.sign(XMLSignContext)` method imports the node into the target document before generating the signature.
