This property returns a XmlNamedNodeMap for the nodes that can return attributes. These are the Element, Entity, and Notation nodes. This property is NULL for all other node types.

Clones a new node.
public : IXmlNode CloneNode(bool deep)public IXmlNode CloneNode(Boolean deep)Public Function CloneNode(deep As Boolean) As IXmlNode// You can use this method in JavaScript.
- deep
- bool Boolean Boolean Boolean
A flag that indicates whether to recursively clone all nodes that are descendants of this node. If true, this method creates a clone of the complete tree below this node. If false, this method clones this node and its attributes only.
GetXml() GetXml() GetXml() GetXml()
Returns the XML representation of the node and all its descendants.
public : PlatForm::String GetXml()public string GetXml()Public Function GetXml() As string// You can use this method in JavaScript.
The XML representation of the node and all its descendants.
HasChildNodes() HasChildNodes() HasChildNodes() HasChildNodes()
Determines whether a node has children.
public : PlatForm::Boolean HasChildNodes()public bool HasChildNodes()Public Function HasChildNodes() As bool// You can use this method in JavaScript.
True if this node has children; otherwise false.
InsertBefore(IXmlNode, IXmlNode) InsertBefore(IXmlNode, IXmlNode) InsertBefore(IXmlNode, IXmlNode) InsertBefore(IXmlNode, IXmlNode)
Inserts a child node to the left of the specified node, or at the end of the list.
public : IXmlNode InsertBefore(IXmlNode newChild, IXmlNode referenceChild)public IXmlNode InsertBefore(IXmlNode newChild, IXmlNode referenceChild)Public Function InsertBefore(newChild As IXmlNode, referenceChild As IXmlNode) As IXmlNode// You can use this method in JavaScript.
The address of the new node to be inserted. The node passed here must be a valid child of the current XML DOM document node. For example, if the current node is an attribute, you cannot pass another attribute in the newChild parameter, because an attribute cannot have an attribute as a child. If newChild is a DOCUMENT_FRAGMENT node type, all its children are inserted in order before referenceChild.
If newChild is already in the tree, it is first removed before it is reinserted before the referenceChild node. Read-only nodes, such as NODE_DOCUMENT_TYPE and NODE_ENTITY nodes, cannot be passed in the newChild parameter.
The reference node. The node specified is where the newChild node is to be inserted to the left as the preceding sibling in the child list. The node passed here must be a either a child node of the current node or null. If the value is null, the newChild node is inserted at the end of the child list. If the referenceChild node is not a child of the current node, an error is returned.
