The following table shows the supported XPath node types for this method.

XPathNodeType

WriteNode Behavior

Root

Writes out all the nodes irrespective of type. That is, the writer consumes the XPathNavigator and writes out all the nodes from the root node (including attributes, processing instructions, comments and so on.)

Element

Writes out the element node and any attribute nodes.

Attribute

No operation. Use WriteStartAttribute or WriteAttributeString instead.

Text

Writes out the text node.

Namespace

No operation. Use the WriteStartAttribute or WriteAttributeString method to write the namespace declaration.

ProcessingInstruction

Writes out the processing instruction node.

Comment

Writes out the comment node.

SignificantWhitespace

Writes out the significant white space node.

Whitespace

Writes out the white space node.

For the asynchronous version of this method, see WriteNodeAsync.
