XPathNavigator.OuterXml Property

Gets or sets the markup representing the opening and closing tags of the current node and its child nodes.

Namespace:  System.Xml.XPath
Assembly:  System.Xml (in System.Xml.dll)

public virtual string OuterXml { get; set; }

Property Value

Type: System.String
A String that contains the markup representing the opening and closing tags of the current node and its child nodes.


The InnerXml and OuterXml properties are not very efficient. If performance is a priority, it is more efficient to use the node navigation methods of the XPathNavigator to get values of child nodes.

The following example uses the OuterXml property to display the contents of the first book element in the contosoBooks.xml file, its child nodes, and its opening and closing tags in the XPathNavigator.

XPathDocument document = new XPathDocument("contosoBooks.xml");
XPathNavigator navigator = document.CreateNavigator();

navigator.MoveToChild("bookstore", "");
navigator.MoveToChild("book", "");


The example takes the contosoBooks.xml file as an input.

<?xml version="1.0" encoding="utf-8" ?>
<bookstore xmlns="">
    <book genre="autobiography" publicationdate="1981-03-22" ISBN="1-861003-11-0">
