XmlReader.MoveToNextAttribute Method

.NET Framework 4.5

When overridden in a derived class, moves to the next attribute.

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

public abstract bool MoveToNextAttribute()

Return Value

Type: System.Boolean
true if there is a next attribute; false if there are no more attributes.

Exceptions

Exception	Condition
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.”

Remarks

If the current node is an element node, this method is equivalent to MoveToFirstAttribute. If MoveToNextAttribute returns true, the reader moves to the next attribute; otherwise, the position of the reader does not change.

Examples

The following example displays all attributes on the current node.

if (reader.HasAttributes) {
  Console.WriteLine("Attributes of <" + reader.Name + ">");
  while (reader.MoveToNextAttribute()) {
    Console.WriteLine(" {0}={1}", reader.Name, reader.Value);
  }
  // Move the reader back to the element node.
  reader.MoveToElement();
}
