The XmlDocument has a create method for all of the node types. Supply the method with a name when required, and content or other parameters for those nodes that have content (for example, a text node), and the node is created. The following methods are ones that need a name and a few other parameters filled to create an appropriate node.
Other node types have more requirements than just providing data to parameters.
For information on attributes, see Creating New Attributes for Elements in the DOM. For information on element and attribute name validation, see XML Element and Attribute Name Verification when Creating New Nodes. For creating entity references, see Creating New Entity References. For information on how namespaces affect the expansion of entity references, see Namespace Affect on Entity Reference Expansion for New Nodes Containing Elements and Attributes.
Once new nodes are created, there are several methods available to insert them into the tree. The table lists the methods with a description of where the new node appears in the XML Document Object Model (DOM).
|InsertBefore||Inserted before the reference node. For example, to insert the new node in position 5:
For more information, see the InsertBefore method.
|InsertAfter||Inserted after the reference node. For example:
For more information, see the InsertAfter method.
|AppendChild||Adds the node to the end of the list of child nodes for the given node. If the node being added is an XmlDocumentFragment, the entire contents of the document fragment are moved into the child list of this node. For more information, see the AppendChild method.|
|PrependChild||Adds the node to the beginning of the list of child nodes of the given node. If the node being added is an XmlDocumentFragment, the entire contents of the document fragment are moved into the child list of this node. For more information, see the PrependChild method.|
|Append||Appends an XmlAttribute node to the end of the attribute collection associated with an element. For more information, see the Append method.|
