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.
Specified by:
getAttributeNS in interface org.w3c.dom.Element
Overrides:
getAttributeNS 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 value as a string, or the empty string if that attribute does not have a specified or default value.

getElementsByTagName

public final org.w3c.dom.NodeList getElementsByTagName(java.lang.String tagName)
Description copied from interface: org.w3c.dom.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.

                                                         java.lang.String localName)
Description copied from interface: 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. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

getElementsByTagNameNS in interface org.w3c.dom.Element
Overrides:
getElementsByTagNameNS in class org.apache.xerces.dom.ElementImpl
