Constructor Detail

DOMElementImpl

protected DOMElementImpl(Node adaptee)
Method Detail

getNodeType

public short getNodeType()
Description copied from interface: Node
A code representing the type of the underlying object, as defined above.
Specified by:
getNodeType in interface Node
Overrides:
getNodeType in class DOMNodeImpl
See Also:
Node.getNodeType()

getTagName

public java.lang.String getTagName()
Description copied from interface: Element
The name of the element. For example, in:
 <elementExample 
 id="demo"> ... </elementExample> , 
tagName has the value "elementExample". Note that this is case-preserving in XML, as are all of the operations of the DOM. The HTML DOM returns the tagName of an HTML element in the canonical uppercase form, regardless of the case in the source HTML document.
Specified by:
getTagName in interface Element
See Also:
Element.getTagName()

getAttribute

public java.lang.String getAttribute(java.lang.String name)
Description copied from interface: Element
Retrieves an attribute value by name.
Specified by:
getAttribute in interface Element
See Also:
Element.getAttribute(java.lang.String)

setAttribute

public void setAttribute(java.lang.String name,
                         java.lang.String value)
                  throws DOMException
Description copied from interface: Element
Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute.
To set an attribute with a qualified name and namespace URI, use the setAttributeNS method.
Specified by:
setAttribute in interface Element
See Also:
Element.setAttribute(java.lang.String, java.lang.String)

removeAttribute

public void removeAttribute(java.lang.String name)
                     throws DOMException
Description copied from interface: Element
Removes an attribute by name. If the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.
To remove an attribute by local name and namespace URI, use the removeAttributeNS method.
Specified by:
removeAttribute in interface Element
See Also:
Element.removeAttribute(java.lang.String)

getAttributeNode

public Attr getAttributeNode(java.lang.String name)
Description copied from interface: Element
Retrieves an attribute node by name.
To retrieve an attribute node by qualified name and namespace URI, use the getAttributeNodeNS method.
Specified by:
getAttributeNode in interface Element
See Also:
Element.getAttributeNode(java.lang.String)

setAttributeNode

public Attr setAttributeNode(Attr newAttr)
                      throws DOMException
Description copied from interface: Element
Adds a new attribute node. If an attribute with that name ( nodeName) is already present in the element, it is replaced by the new one.
To add a new attribute node with a qualified name and namespace URI, use the setAttributeNodeNS method.
Specified by:
setAttributeNode in interface Element
See Also:
Element.setAttributeNode(org.w3c.dom.Attr)

removeAttributeNode

public Attr removeAttributeNode(Attr oldAttr)
                         throws DOMException
Description copied from interface: Element
Removes the specified attribute node. If the removed Attr has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix, when applicable.
Specified by:
removeAttributeNode in interface Element
See Also:
Element.removeAttributeNode(org.w3c.dom.Attr)

getElementsByTagName

public NodeList getElementsByTagName(java.lang.String name)
Description copied from interface: Element
Returns a NodeList of all descendant Elements with a given tag name, in the order in which they are encountered in a preorder traversal of this Element tree.
Specified by:
getElementsByTagName in interface Element
See Also:
Element.getElementsByTagName(java.lang.String)

normalize

public void normalize()
Description copied from interface: Node
Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.
Specified by:
normalize in interface Node
Overrides:
normalize in class DOMNodeImpl
See Also:
Node.normalize()

getAttributeNS
