member this.NextAttribute : System.Xml.Linq.XAttribute

Public ReadOnly Property NextAttribute As XAttribute

Property Value

XAttribute

An XAttribute containing the next attribute of the parent element.

Examples

The following example shows how to iterate through the attributes of an element using this property.

XElement root = new XElement("Root",  
    new XAttribute("Att1", 1),  
    new XAttribute("Att2", 2),  
    new XAttribute("Att3", 3),  
    new XAttribute("Att4", 4)  
);  

XAttribute att = root.FirstAttribute;  
do {  
    Console.WriteLine(att);  
}  
while((att = att.NextAttribute) != null);

Dim root As XElement = <Root Att1="1" Att2="2" Att3="3" Att4="4"/>  
Dim att As XAttribute = root.FirstAttribute  
Dim val As Boolean = True  
Do  
    Console.WriteLine(att)  
    att = att.NextAttribute  
Loop While (Not (att Is Nothing))

This example produces the following output:

Att1="1"  
Att2="2"  
Att3="3"  
Att4="4"

Remarks

Attributes are maintained in the XML tree in the order that they were added to the element. When a collection of attributes is returned by Attributes, they are returned in the order that they were added, and are not sorted. When you request the next attribute through this property, this property returns the attribute that was added after this attribute.

If this attribute does not have a parent, or if there is no next attribute, then this property returns null.
