public class ElementImpl
extends ParentNode
implements Element, TypeInfo

Elements represent most of the "markup" and structure of the document. They contain both the data for the element itself (element name and attributes), and any contained nodes, including document text (as children).

Elements may have Attributes associated with them; the API for this is defined in Node, but the function is implemented here. In general, XML applications should retrive Attributes as Nodes, since they may contain entity references and hence be a fairly complex sub-tree. HTML users will be dealing with simple string values, and convenience methods are provided to work in terms of Strings.

ElementImpl does not support Namespaces. ElementNSImpl, which inherits from it, does.

Constructor Detail

ElementImpl

public ElementImpl(CoreDocumentImpl ownerDoc,
                   java.lang.String name)

Factory constructor.

Method Detail

getNodeType

public short getNodeType()

A short integer indicating what type of node this is. The named constants for this value are defined in the org.w3c.dom.Node interface.

Specified by:

getNodeType in interface Node

Specified by:

getNodeType in class NodeImpl

getNodeName

public java.lang.String getNodeName()

Returns the element name

Specified by:

getNodeName in interface Node

Specified by:

getNodeName in class NodeImpl

getAttributes

public NamedNodeMap getAttributes()

Retrieve all the Attributes as a set. Note that this API is inherited from Node rather than specified on Element; in fact only Elements will ever have Attributes, but they want to allow folks to "blindly" operate on the tree as a set of Nodes.

Specified by:

getAttributes in interface Node

Overrides:

getAttributes in class NodeImpl

See Also:

ElementImpl

cloneNode

public Node cloneNode(boolean deep)

Return a duplicate copy of this Element. Note that its children will not be copied unless the "deep" flag is true, but Attributes are always replicated.

Specified by:

cloneNode in interface Node

Overrides:

cloneNode in class ParentNode

Parameters:

deep - If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).

Returns:

The duplicate node.

See Also:

Node.cloneNode(boolean)

getBaseURI

public java.lang.String getBaseURI()

DOM Level 3 WD - Experimental. Retrieve baseURI

Specified by:

getBaseURI in interface Node

Overrides:

getBaseURI in class NodeImpl

getAttribute

public java.lang.String getAttribute(java.lang.String name)

Look up a single Attribute by name. Returns the Attribute's string value, or an empty string (NOT null!) to indicate that the name did not map to a currently defined attribute.

Note: Attributes may contain complex node trees. This method returns the "flattened" string obtained from Attribute.getValue(). If you need the structure information, see getAttributeNode().

Specified by:

getAttribute in interface Element

Parameters:

name - The name of the attribute to retrieve.

Returns:

The Attr value as a string, or the empty string if that attribute does not have a specified or default value.

getAttributeNode

public Attr getAttributeNode(java.lang.String name)

Look up a single Attribute by name. Returns the Attribute Node, so its complete child tree is available. This could be important in XML, where the string rendering may not be sufficient information.

If no matching attribute is available, returns null.

Specified by:

getAttributeNode in interface Element

Parameters:

name - The name (nodeName) of the attribute to retrieve.

Returns:

The Attr node with the specified name ( nodeName) or null if there is no such attribute.

getElementsByTagName

public NodeList getElementsByTagName(java.lang.String tagname)

Returns a NodeList of all descendent nodes (children, grandchildren, and so on) which are Elements and which have the specified tag name.

Note: NodeList is a "live" view of the DOM. Its contents will change as the DOM changes, and alterations made to the NodeList will be reflected in the DOM.

Specified by:

getElementsByTagName in interface Element

Parameters:

tagname - The type of element to gather. To obtain a list of all elements no matter what their names, use the wild-card tag name "*".

Returns:

A list of matching Element nodes.

See Also:

DeepNodeListImpl

getTagName

public java.lang.String getTagName()

Returns the name of the Element. Note that Element.nodeName() is defined to also return the tag name.

This is case-preserving in XML. HTML should uppercasify it on the way in.

Specified by:

getTagName in interface Element

normalize

public void normalize()

In "normal form" (as read from a source file), there will never be two Text children in succession. But DOM users may create successive Text nodes in the course of manipulating the document. Normalize walks the sub-tree and merges adjacent Texts, as if the DOM had been written out and read back in again. This simplifies implementation of higher-level functions that may want to assume that the document is in standard form.

To normalize a Document, normalize its top-level Element child.

As of PR-DOM-Level-1-19980818, CDATA -- despite being a subclass of Text -- is considered "markup" and will _not_ be merged either with normal Text or with other CDATASections.

Specified by:

normalize in interface Node

Overrides:

normalize in class ParentNode

removeAttribute

public void removeAttribute(java.lang.String name)

Remove the named attribute from this Element. If the removed Attribute has a default value, it is immediately replaced thereby.

The default logic is actually implemented in NamedNodeMapImpl. PR-DOM-Level-1-19980818 doesn't fully address the DTD, so some of this behavior is likely to change in future versions. ?????

Note that this call "succeeds" even if no attribute by this name existed -- unlike removeAttributeNode, which will throw a not-found exception in that case.

Specified by:

removeAttribute in interface Element

Parameters:

name - The name of the attribute to remove.

Throws:

DOMException(NO_MODIFICATION_ALLOWED_ERR) - if the node is readonly.

removeAttributeNode

public Attr removeAttributeNode(Attr oldAttr)
                         throws DOMException

Remove the specified attribute/value pair. If the removed Attribute has a default value, it is immediately replaced.

NOTE: Specifically removes THIS NODE -- not the node with this name, nor the node with these contents. If the specific Attribute object passed in is not stored in this Element, we throw a DOMException. If you really want to remove an attribute by name, use removeAttribute().

Specified by:

removeAttributeNode in interface Element

Parameters:

oldAttr - The Attr node to remove from the attribute list.

Returns:

the Attribute object that was removed.

Throws:

DOMException(NOT_FOUND_ERR) - if oldattr is not an attribute of this Element.

DOMException(NO_MODIFICATION_ALLOWED_ERR) - if the node is readonly.

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if oldAttr is not an attribute of the element.

setAttribute

public void setAttribute(java.lang.String name,
                         java.lang.String value)

Add a new name/value pair, or replace the value of the existing attribute having that name. Note: this method supports only the simplest kind of Attribute, one whose value is a string contained in a single Text node. If you want to assert a more complex value (which XML permits, though HTML doesn't), see setAttributeNode(). The attribute is created with specified=true, meaning it's an explicit value rather than inherited from the DTD as a default. Again, setAttributeNode can be used to achieve other results.

Specified by:

setAttribute in interface Element

Parameters:

name - The name of the attribute to create or alter.

value - Value to set in string form.

Throws:

DOMException(INVALID_NAME_ERR) - if the name is not acceptable. (Attribute factory will do that test for us.)

DOMException(NO_MODIFICATION_ALLOWED_ERR) - if the node is readonly.

setAttributeNode

public Attr setAttributeNode(Attr newAttr)
                      throws DOMException

Add a new attribute/value pair, or replace the value of the existing attribute with that name.

This method allows you to add an Attribute that has already been constructed, and hence avoids the limitations of the simple setAttribute() call. It can handle attribute values that have arbitrarily complex tree structure -- in particular, those which had entity references mixed into their text.

Specified by:

setAttributeNode in interface Element

Parameters:

newAttr - The Attr node to add to the attribute list.

Returns:

If the newAttr attribute replaces an existing attribute, the replaced Attr node is returned, otherwise null is returned.

Throws:

DOMException(INUSE_ATTRIBUTE_ERR) - if the Attribute object has already been assigned to another Element.

DOMException - WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.

getAttributeNS

public java.lang.String getAttributeNS(java.lang.String namespaceURI,
                                       java.lang.String localName)

Introduced in DOM Level 2.

Retrieves an attribute value by local name and namespace URI.

Specified by:

getAttributeNS in interface Element

Parameters:

namespaceURI - The namespace URI of the attribute to retrieve.

localName - The local name of the attribute to retrieve.

Returns:

String The Attr value as a string, or empty string if that attribute does not have a specified or default value.

Since:

WD-DOM-Level-2-19990923

setAttributeNS

public void setAttributeNS(java.lang.String namespaceURI,
                           java.lang.String qualifiedName,
                           java.lang.String value)

Introduced in DOM Level 2.

Adds a new attribute. If the given namespaceURI is null or an empty string and the qualifiedName has a prefix that is "xml", the new attribute is bound to the predefined namespace "http://www.w3.org/XML/1998/namespace" [Namespaces]. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be 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 setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute.

Specified by:

setAttributeNS in interface Element

Parameters:

namespaceURI - The namespace URI of the attribute to create or alter.

qualifiedName - The qualified name of the attribute to create or alter.

value - The value to set in string form.

Throws:

INVALID_CHARACTER_ERR: - Raised if the specified name contains an invalid character.

NO_MODIFICATION_ALLOWED_ERR: - Raised if this node is readonly.

NAMESPACE_ERR: - Raised if the qualifiedName has a prefix that is "xml" and the namespaceURI is neither null nor an empty string nor "http://www.w3.org/XML/1998/namespace", or if the qualifiedName has a prefix that is "xmlns" but the namespaceURI is neither null nor an empty string, or if if the qualifiedName has a prefix different from "xml" and "xmlns" and the namespaceURI is null or an empty string.

WD-DOM-Level-2-19990923

removeAttributeNS

public void removeAttributeNS(java.lang.String namespaceURI,
                              java.lang.String localName)

Introduced in DOM Level 2.

Removes an attribute by local name and namespace URI. If the removed attribute 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.

Specified by:

removeAttributeNS in interface Element

Parameters:

namespaceURI - The namespace URI of the attribute to remove.

localName - The local name of the attribute to remove.

Throws:

NO_MODIFICATION_ALLOWED_ERR: - Raised if this node is readonly.

public Attr getAttributeNodeNS(java.lang.String namespaceURI,
                               java.lang.String localName)

Retrieves an Attr node by local name and namespace URI.

Specified by:

getAttributeNodeNS in interface Element

Parameters:

namespaceURI - The namespace URI of the attribute to retrieve.

localName - The local name of the attribute to retrieve.

Returns:

Attr The Attr node with the specified attribute local name and namespace URI or null if there is no such attribute.

Since:

WD-DOM-Level-2-19990923

setAttributeNodeNS

public Attr setAttributeNodeNS(Attr newAttr)
                        throws DOMException

Introduced in DOM Level 2.

Adds a new attribute. If an attribute with that local name and namespace URI is already present in the element, it is replaced by the new one.

Specified by:

setAttributeNodeNS in interface Element

Parameters:

newAttr - The Attr node to add to the attribute list. When the Node has no namespaceURI, this method behaves like setAttributeNode.

Returns:

Attr If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the * previously existing Attr node is returned, otherwise null is returned.

Throws:

WRONG_DOCUMENT_ERR: - Raised if newAttr was created from a different document than the one that created the element.

NO_MODIFICATION_ALLOWED_ERR: - Raised if this node is readonly.

INUSE_ATTRIBUTE_ERR: - Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.

DOMException - WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.
NOT_SUPPORTED_ERR: May be raised if the implementation does not support the feature "XML" and the language exposed through the Document does not support XML Namespaces (such as [HTML 4.01]).
