Method Detail

getOwnerDocument

public org.w3c.dom.Document getOwnerDocument()

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

The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.

Specified by:

Overrides:

getOwnerDocument in class DefaultNode

getParentNode

public org.w3c.dom.Node getParentNode()

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

The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.

Specified by:

getParentNode in interface org.w3c.dom.Node

Overrides:

getParentNode in class DefaultNode

hasChildNodes

public boolean hasChildNodes()

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

Returns whether this node has any children.

Specified by:

hasChildNodes in interface org.w3c.dom.Node

Overrides:

hasChildNodes in class DefaultNode

getFirstChild

public org.w3c.dom.Node getFirstChild()

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

The first child of this node. If there is no such node, this returns null.

Specified by:

Overrides:

getFirstChild in class DefaultNode

getLastChild

public org.w3c.dom.Node getLastChild()

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

The last child of this node. If there is no such node, this returns null.

Specified by:

getLastChild in interface org.w3c.dom.Node

Overrides:

getLastChild in class DefaultNode

getPreviousSibling

public org.w3c.dom.Node getPreviousSibling()

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

The node immediately preceding this node. If there is no such node, this returns null.

Specified by:

getPreviousSibling in interface org.w3c.dom.Node

Overrides:

getPreviousSibling in class DefaultNode

getNextSibling

public org.w3c.dom.Node getNextSibling()

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

The node immediately following this node. If there is no such node, this returns null.

Specified by:

getNextSibling in interface org.w3c.dom.Node

Overrides:

getNextSibling in class DefaultNode

getAttributes

public org.w3c.dom.NamedNodeMap getAttributes()

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

A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.

Specified by:

getAttributes in interface org.w3c.dom.Node

Overrides:

getAttributes in class DefaultNode

hasAttributes

public boolean hasAttributes()

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

Returns whether this node (if it is an element) has any attributes.

Specified by:

hasAttributes in interface org.w3c.dom.Node

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.

Specified by:

getTagName in interface org.w3c.dom.Element

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.

Specified by:

getAttribute in interface org.w3c.dom.Element

Overrides:

getAttribute in class DefaultElement

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.

Specified by:

getAttributeNode in interface org.w3c.dom.Element

Overrides:

getAttributeNode in class DefaultElement

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 DefaultElement

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 DefaultElement

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.

Specified by:

hasAttribute in interface org.w3c.dom.Element

Overrides:

hasAttribute in class DefaultElement

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.

Specified by:

hasAttributeNS in interface org.w3c.dom.Element

Overrides:

hasAttributeNS in class DefaultElement

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.

Specified by:

setAttribute in interface org.w3c.dom.Element

Overrides:

setAttribute in class DefaultElement

getLineNumber

public int getLineNumber()

Returns the line number.

getColumnNumber

public int getColumnNumber()

Returns the column number.
