ReadToNextSibling(String)

Source:

Advances the XmlReader to the next sibling element with the specified qualified name.

C#

public virtual bool ReadToNextSibling(string name);

Parameters

name

String

The qualified name of the sibling element you wish to move to.

Returns

Boolean

true if a matching sibling element is found; otherwise false. If a matching sibling element is not found, the XmlReader is positioned on the end tag (NodeType is XmlNodeType.EndElement) of the parent element.

Exceptions

InvalidOperationException

An XmlReader method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

ArgumentException

The parameter is an empty string.

Examples

The following example reads the ISBN attribute on each book node.

C#

using (XmlReader reader = XmlReader.Create("books.xml")) {
    reader.ReadToFollowing("book");
    do {
       Console.WriteLine("ISBN: {0}", reader.GetAttribute("ISBN"));
    } while (reader.ReadToNextSibling("book"));
}

Remarks

Note

Do not call ReadToNextSibling when the XmlReader is an initial state (ReadState is Initial). You can call Read to advance the XmlReader and then call the ReadToNextSibling method.
