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.

The element's advisory title. See the title attribute definition in HTML 4.0.

Specified by:

getTitle in interface org.w3c.dom.html.HTMLElement

setTitle

public void setTitle(java.lang.String title)

Specified by:

setTitle in interface org.w3c.dom.html.HTMLElement

getLang

public java.lang.String getLang()

Description copied from interface: org.w3c.dom.html.HTMLElement

Language code defined in RFC 1766. See the lang attribute definition in HTML 4.0.

Specified by:

getLang in interface org.w3c.dom.html.HTMLElement

setLang

public void setLang(java.lang.String lang)

Specified by:

setLang in interface org.w3c.dom.html.HTMLElement

getDir

public java.lang.String getDir()

Description copied from interface: org.w3c.dom.html.HTMLElement

Specifies the base direction of directionally neutraltext and the directionality of tables. See the dir attribute definition in HTML 4.0.

Specified by:

getDir in interface org.w3c.dom.html.HTMLElement

setDir

public void setDir(java.lang.String dir)

Specified by:

setDir in interface org.w3c.dom.html.HTMLElement

getClassName

public java.lang.String getClassName()

Description copied from interface: org.w3c.dom.html.HTMLElement

The class attribute of the element. This attribute has been renameddue to conflicts with the "class" keyword exposed by many languages. See the class attribute definition in HTML 4.0.

Specified by:

getClassName in interface org.w3c.dom.html.HTMLElement

setClassName

public void setClassName(java.lang.String className)

Specified by:

setClassName in interface org.w3c.dom.html.HTMLElement

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

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

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.

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

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

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.

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.

Specified by:

getElementsByTagName in interface org.w3c.dom.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 "*".

DeepNodeListImpl

getElementsByTagNameNS

public final org.w3c.dom.NodeList getElementsByTagNameNS(java.lang.String namespaceURI,
                                                         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.

Specified by:

getElementsByTagNameNS in interface org.w3c.dom.Element

Parameters:

namespaceURI - The namespace URI of the elements to match on. The special value "*" matches all namespaces. When it is null or an empty string, this method behaves like getElementsByTagName.

localName - The local name of the elements to match on. The special value "*" matches all local names.

Returns:

NodeList A new NodeList object containing all the matched Elements.

getForm

public org.w3c.dom.html.HTMLFormElement getForm()

Convenience method returns the form in which this form element is contained. This method is exposed for form elements through the DOM API, but other elements have no access to it through the API.
