 </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.

public void removeAttribute (String name) throws DOMException

Removes an attribute by name.

Removes an attribute by name. If a default value for the removed
attribute is defined in the DTD, a new attribute immediately appears
with the default value as well as the corresponding namespace URI,
local name, and prefix when applicable. The implementation may handle
default values from other schemas similarly but applications should
use Document.normalizeDocument() to guarantee this
information is up-to-date.

If no attribute with this name is found, this method has no effect.

To remove an attribute by local name and namespace URI, use the
removeAttributeNS method.
Parameters:
- name - The name of the attribute to remove.
Throws:
- DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

public Attr removeAttributeNode (Attr oldAttr) throws DOMException

Removes the specified attribute node.

Removes the specified attribute node. If a default value for the
removed Attr node is defined in the DTD, a new node
immediately appears with the default value as well as the
corresponding namespace URI, local name, and prefix when applicable.
The implementation may handle default values from other schemas
similarly but applications should use
Document.normalizeDocument() to guarantee this
information is up-to-date.
Returns: The Attr node that was removed.
Parameters:
- oldAttr - The Attr node to remove from the attribute list.
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.

public void removeAttributeNS (String namespaceURI, String localName) throws DOMException

Removes an attribute by local name and namespace URI.

Removes an attribute by local name and namespace URI. If a default
value for the removed attribute is defined in the DTD, a new
attribute immediately appears with the default value as well as the
corresponding namespace URI, local name, and prefix when applicable.
The implementation may handle default values from other schemas
similarly but applications should use
Document.normalizeDocument() to guarantee this
information is up-to-date.

If no attribute with this local name and namespace URI is found,
this method has no effect.

Per [XML Namespaces]
, applications must use the value null as the
namespaceURI parameter for methods if they wish to have
no namespace.
Parameters:
- namespaceURI - The namespace URI of the attribute to remove.
- localName - The local name of the attribute to remove.
Throws:
- DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
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]).
Since: DOM Level 2

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

Adds a new attribute.

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.
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 is not an XML name according to the XML version in use specified in the Document.xmlVersion attribute.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

public Attr setAttributeNode (Attr newAttr) throws DOMException

Adds a new attribute node.

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. Replacing an attribute node by itself has no
effect.

To add a new attribute node with a qualified name and namespace
URI, use the setAttributeNodeNS method.
Returns: If the newAttr attribute replaces an existing attribute, the replaced Attr node is returned, otherwise null is returned.
Parameters:
- newAttr - The Attr node to add to the attribute list.
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.

public Attr setAttributeNodeNS (Attr newAttr) throws DOMException

Adds a new attribute.

Adds a new attribute. If an attribute with that local name and that
namespace URI is already present in the element, it is replaced by
the new one. Replacing an attribute node by itself has no effect.

Per [XML Namespaces]
, applications must use the value null as the
namespaceURI parameter for methods if they wish to have
no namespace.
Returns: If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the replaced Attr node is returned, otherwise null is returned.
Parameters:
- newAttr - The Attr node to add to the attribute list.
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.
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]).
Since: DOM Level 2

public void setAttributeNS (String namespaceURI, String qualifiedName, String value) throws DOMException

Adds a new attribute.

Adds a new attribute. 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.

Per [XML Namespaces]
, applications must use the value null as the
namespaceURI parameter for methods if they wish to have
no namespace.
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:
- DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name is not an XML name according to the XML version in use specified in the Document.xmlVersion attribute.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the qualifiedName is malformed per the Namespaces in XML specification, if the qualifiedName has a prefix and the namespaceURI is null, if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from " http://www.w3.org/XML/1998/namespace", if the qualifiedName or its prefix is "xmlns" and the namespaceURI is different from "http://www.w3.org/2000/xmlns/", or if the namespaceURI is "http://www.w3.org/2000/xmlns/" and neither the qualifiedName nor its prefix is "xmlns".
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]).
Since: DOM Level 2

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 .

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.
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.
