Method Details

getTagName

public String getTagName()

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

getAttribute

public String getAttribute(String name)

Retrieves an attribute value by name.

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.

setAttribute

public void setAttribute(String name,
 String value)
                  throws DOMException

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.

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_CHARACTER_ERR: Raised if the specified name contains an invalid character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

removeAttribute

public void removeAttribute(String name)
                     throws DOMException

Removes an attribute by name. If the removed attribute has a default value it is immediately replaced.

Specified by:

removeAttribute in interface Element

Parameters:

name - The name of the attribute to remove.

Throws:

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

getAttributeNode

public Attr getAttributeNode(String name)

Retrieves an Attr node by name.

Specified by:

getAttributeNode in interface Element

Parameters:

name - The name of the attribute to retrieve.

Returns:

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

setAttributeNode

public Attr setAttributeNode(Attr newAttr)
                      throws DOMException

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

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 with the same name, the previously existing Attr node is returned, otherwise null is returned.

Throws:

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.

removeAttributeNode

public Attr removeAttributeNode(Attr oldAttr)
                         throws DOMException

Removes the specified attribute.

Specified by:

removeAttributeNode in interface Element

Parameters:

oldAttr - The Attr node to remove from the attribute list. If the removed Attr has a default value it is immediately replaced.

Returns:

The Attr node that was removed.

Throws:

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

getElementsByTagName

public NodeList getElementsByTagName(String name)

Returns a NodeList of all descendant elements with a given tag name, in the order in which they would be encountered in a preorder traversal of the Element tree.

Specified by:

getElementsByTagName in interface Element

Parameters:

name - The name of the tag to match on. The special value "*" matches all tags.

Returns:

A list of matching Element nodes.

normalize

public void normalize()

Puts all Text nodes in the full depth of the sub-tree underneath this Element into a "normal" form where only markup (for example, tags, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, that is , there are no adjacent 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.

Specified by:

normalize in interface Node

Overrides:

normalize in class PMRNodeImpl

removeAttributeNS

 String t)

getSchemaTypeInfo

public TypeInfo getSchemaTypeInfo()

The type information associated with this element.

Specified by:

getSchemaTypeInfo in interface Element

Since:

DOM Level 3

setIdAttribute

public void setIdAttribute(String name,
 boolean isId)
                    throws DOMException

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute . This affects the value of Attr.isId and the behavior of Document.getElementById, but does not change any schema that may be in use, in particular this does not affect the Attr.schemaTypeInfo of the specified Attr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.
To specify an attribute by local name and namespace URI, use the setIdAttributeNS method.

Specified by:

setIdAttribute in interface Element

Parameters:

name - The name of the attribute.

isId - Whether the attribute is a of type ID.

Throws:

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

Since:

DOM Level 3

setIdAttributeNS

public void setIdAttributeNS(String namespaceURI,
 String localName,
 boolean isId)
                      throws DOMException

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute . This affects the value of Attr.isId and the behavior of Document.getElementById, but does not change any schema that may be in use, in particular this does not affect the Attr.schemaTypeInfo of the specified Attr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.

Specified by:

setIdAttributeNS in interface Element

Parameters:

namespaceURI - The namespace URI of the attribute.

localName - The local name of the attribute.

isId - Whether the attribute is a of type ID.

Throws:

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

Since:

DOM Level 3

setIdAttributeNode

public void setIdAttributeNode(Attr idAttr,
 boolean isId)
                        throws DOMException

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute . This affects the value of Attr.isId and the behavior of Document.getElementById, but does not change any schema that may be in use, in particular this does not affect the Attr.schemaTypeInfo of the specified Attr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.

Specified by:

setIdAttributeNode in interface Element

Parameters:

idAttr - The attribute node.
