XPathNavigator.InnerXml Property


Gets or sets the markup representing the child nodes of the current node.

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

public virtual string InnerXml { get; set; }

Property Value

Type: System.String

A String that contains the markup of the child nodes of the current node.

Exception Condition

The InnerXml property cannot be set.


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 InnerXml property to display the contents of the first book element in the contosoBooks.xml file and its child nodes in the XPathNavigator.

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

navigator.MoveToChild("bookstore", "http://www.contoso.com/books");
navigator.MoveToChild("book", "http://www.contoso.com/books");


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

<?xml version="1.0" encoding="utf-8" ?>
<bookstore xmlns="http://www.contoso.com/books">
    <book genre="autobiography" publicationdate="1981-03-22" ISBN="1-861003-11-0">
        <title>The Autobiography of Benjamin Franklin</title>
    <book genre="novel" publicationdate="1967-11-17" ISBN="0-201-63361-2">
        <title>The Confidence Man</title>
    <book genre="philosophy" publicationdate="1991-02-15" ISBN="1-861001-57-6">
        <title>The Gorgias</title>
