- public class HTMLElementImpl
- extends org.apache.xerces.dom.ElementImpl
- implements org.w3c.dom.html.HTMLElement
Implements an HTML-specific element, an Element
that
will only appear inside HTML documents. This element extends ElementImpl
by adding methods for directly
manipulating HTML-specific attributes. All HTML elements gain access to
the id
, title
, lang
,
dir
and class
attributes. Other elements
add their own specific attributes.

getAttributeNode
public org.w3c.dom.Attr getAttributeNode(java.lang.String attrName)
- Description copied from interface:
org.w3c.dom.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 org.w3c.dom.Element
- Overrides:
getAttributeNode
in class org.apache.xerces.dom.ElementImpl
- Following copied from interface:
org.w3c.dom.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.
getAttributeNodeNS
public org.w3c.dom.Attr getAttributeNodeNS(java.lang.String namespaceURI,
java.lang.String localName)
- Description copied from interface:
org.w3c.dom.Element
- Retrieves an
Attr
node by local name and namespace URI.
Documents which do not support the "XML" feature will permit only
the DOM Level 1 calls for creating/setting elements and attributes.
Hence, if you specify a non-null namespace URI, these DOMs will never
find a matching node.
- Specified by:
getAttributeNodeNS
in interface org.w3c.dom.Element
- Overrides:
getAttributeNodeNS
in class org.apache.xerces.dom.ElementImpl
- Following copied from interface:
org.w3c.dom.Element
- Parameters:
namespaceURI
- The namespace URI of the attribute to retrieve.localName
- The local name of the attribute to retrieve.- Returns:
- The
Attr
node with the specified attribute local
name and namespace URI or null
if there is no such
attribute.
getAttribute
public java.lang.String getAttribute(java.lang.String attrName)
- Description copied from interface:
org.w3c.dom.Element
- Retrieves an attribute value by name.
- Specified by:
getAttribute
in interface org.w3c.dom.Element
- Overrides:
getAttribute
in class org.apache.xerces.dom.ElementImpl
- Following copied from interface:
org.w3c.dom.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.
getAttributeNS
public java.lang.String getAttributeNS(java.lang.String namespaceURI,
java.lang.String localName)
- Description copied from interface:
org.w3c.dom.Element
- Retrieves an attribute value by local name and namespace URI.
Documents which do not support the "XML" feature will permit only
the DOM Level 1 calls for creating/setting elements and attributes.
Hence, if you specify a non-null namespace URI, these DOMs will never
find a matching node.

- Following copied from interface:
org.w3c.dom.Element
- Parameters:
namespaceURI
- The namespace URI of the attribute to retrieve.localName
- The local name of the attribute to retrieve.- Returns:
- The

org.w3c.dom.Element
- Returns a
NodeList
of all the descendant
Elements
with a given local name and namespace URI in
the order in which they are encountered in a preorder traversal of
this Element
tree.
Documents which do not support the "XML" feature will permit only
the DOM Level 1 calls for creating/setting elements and attributes.
