                  throws DOMException
Inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children.
If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed.

Specified by:
insertBefore in interface Node
Parameters:
newChildThe - node to insert.
refChildThe - reference node, i.e., the node before which the new node must be inserted.
Returns:
The node being inserted.
Throws:
DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to insert is one of this node's ancestors.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly or if the parent of the node being inserted is readonly.
NOT_FOUND_ERR: Raised if refChild is not a child of this node.

replaceChild

public Node replaceChild(Node newChild,
                         Node oldChild)
                  throws DOMException
Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.
If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.

Specified by:
replaceChild in interface Node
Parameters:
newChildThe - new node to put in the child list.
oldChildThe - node being replaced in the list.
Returns:
The node replaced.
Throws:
DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to put in is one of this node's ancestors.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the parent of the new node is readonly.
NOT_FOUND_ERR: Raised if oldChild is not a child of this node.

removeChild

public Node removeChild(Node oldChild)
                 throws DOMException
Removes the child node indicated by oldChild from the list of children, and returns it.

Specified by:
removeChild in interface Node
Parameters:
oldChildThe - node being removed.
Returns:
The node removed.
Throws:
DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if oldChild is not a child of this node.

appendChild

public Node appendChild(Node newChild)
                 throws DOMException
Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed.

Specified by:
appendChild in interface Node
Parameters:
newChildThe - node to add.If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node
Returns:
The node added.
Throws:
DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to append is one of this node's ancestors.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

hasChildNodes

public boolean hasChildNodes()
Returns whether this node has any children.

Specified by:
hasChildNodes in interface Node
Returns:
true if this node has any children, false otherwise.

normalize

public void normalize()
Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.

Specified by:
normalize in interface Node

isSupported

public boolean isSupported(java.lang.String feature,
                           java.lang.String version)
Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Specified by:
isSupported in interface Node
Parameters:
featureThe - name of the feature to test. This is the same name which can be passed to the method hasFeature on DOMImplementation.
versionThis - is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true.
Returns:
Returns true if the specified feature is supported on this node, false otherwise.
Since:
DOM Level 2

getNamespaceURI

public java.lang.String getNamespaceURI()
The namespace URI of this node, or null if it is unspecified.
This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.Per the Namespaces in XML Specification an attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, it simply has no namespace.

Specified by:
getNamespaceURI in interface Node
Since:
DOM Level 2

getPrefix

public java.lang.String getPrefix()
The namespace prefix of this node, or null if it is unspecified.
Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.
Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:
getPrefix in interface Node
Throws:
DOMException - INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix is malformed, if the namespaceURI of this node is null, if the specified prefix is "xml" and the namespaceURI of this node is different from " http://www.w3.org/XML/1998/namespace", if this node is an attribute and the specified prefix is "xmlns" and the namespaceURI of this node is different from " http://www.w3.org/2000/xmlns/", or if this node is an attribute and the qualifiedName of this node is "xmlns" .
Since:
DOM Level 2

setPrefix

public void setPrefix(java.lang.String prefix)
               throws DOMException
Specified by:
setPrefix in interface Node
Throws:
DOMException

getLocalName

public java.lang.String getLocalName()
Returns the local part of the qualified name of this node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:
getLocalName in interface Node
Since:
DOM Level 2

hasAttributes

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

Specified by:
hasAttributes in interface Node
Returns:
true if this node has any attributes, false otherwise.
Since:
DOM Level 2

item

public Node item(int index)
Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null.

Specified by:
item in interface NodeList
Parameters:
indexIndex - into the collection.
Returns:
The node at the indexth position in the NodeList, or null if that is not a valid index.

getLength

public int getLength()
The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.

Specified by:
getLength in interface NodeList
