Method Detail

getOwnerDocument

public org.w3c.dom.Document getOwnerDocument()

Overrides:

public org.w3c.dom.Node getParentNode()

Overrides:

getParentNode in class DefaultNode

public boolean hasChildNodes()

Overrides:

hasChildNodes in class DefaultNode

getFirstChild

public org.w3c.dom.Node getFirstChild()

Overrides:

getFirstChild in class DefaultNode

getLastChild

public org.w3c.dom.Node getLastChild()

Overrides:

getLastChild in class DefaultNode

getPreviousSibling

public org.w3c.dom.Node getPreviousSibling()

Overrides:

getPreviousSibling in class DefaultNode

getNextSibling

public org.w3c.dom.Node getNextSibling()

Overrides:

getNextSibling in class DefaultNode

getAttributes

public org.w3c.dom.NamedNodeMap getAttributes()

Overrides:

getAttributes in class DefaultNode

hasAttributes

public boolean hasAttributes()

Overrides:

hasAttributes in class DefaultNode

getTagName

public java.lang.String getTagName()

Description copied from interface: org.w3c.dom.Element

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.

Overrides:

getTagName in class DefaultElement

getAttribute

public java.lang.String getAttribute(java.lang.String name)

Description copied from interface: org.w3c.dom.Element

Retrieves an attribute value by name.

Overrides:

getAttribute in class DefaultElement

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.

getAttributeNode

public org.w3c.dom.Attr getAttributeNode(java.lang.String name)

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.

Overrides:

getAttributeNode in class DefaultElement

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.

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.

Overrides:

getAttributeNS in class DefaultElement

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.

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.

Overrides:

getAttributeNodeNS in class DefaultElement

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.

hasAttribute

public boolean hasAttribute(java.lang.String name)

Description copied from interface: org.w3c.dom.Element

Returns true when an attribute with a given name is specified on this element or has a default value, false otherwise.

Overrides:

hasAttribute in class DefaultElement

Following copied from interface: org.w3c.dom.Element

Parameters:

name - The name of the attribute to look for.

Returns:

true if an attribute with the given name is specified on this element or has a default value, false otherwise.

hasAttributeNS

public boolean hasAttributeNS(java.lang.String namespaceURI,
                              java.lang.String localName)

Description copied from interface: org.w3c.dom.Element

Returns true when an attribute with a given local name and namespace URI is specified on this element or has a default value, false otherwise.
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.

Overrides:

hasAttributeNS in class DefaultElement

Following copied from interface: org.w3c.dom.Element

Parameters:

namespaceURI - The namespace URI of the attribute to look for.

localName - The local name of the attribute to look for.

Returns:

true if an attribute with the given local name and namespace URI is specified or has a default value on this element, false otherwise.

setAttribute

public void setAttribute(java.lang.String name,
                         java.lang.String value)

Description copied from interface: org.w3c.dom.Element

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.

Overrides:

setAttribute in class DefaultElement

Following copied from interface: org.w3c.dom.Element

Parameters:

name - The name of the attribute to create or alter.

value - Value to set in string form.

Throws:

org.w3c.dom.DOMException - INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

getLineNumber

public int getLineNumber()

Returns the line number.

getColumnNumber

public int getColumnNumber()

Returns the column number.
