XAttribute::PreviousAttribute Property

Gets the previous attribute of the parent element.

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

public:
property XAttribute^ PreviousAttribute {
	XAttribute^ get ();
}

Property Value

Type: System.Xml.Linq::XAttribute
An XAttribute containing the previous attribute of the parent element.

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 previous attribute through this property, this property returns the attribute that was added before this attribute.

If this attribute does not have a parent, or if this attribute is the first attribute, then this property returns nullptr.

The XElement class stores its attributes as a singly-linked list of XAttribute objects. This means that the PreviousAttribute property must traverse the list of attributes that belong to the element. Therefore, using this property might affect your performance.

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

No code example is currently available or this language may not be supported.

This example produces the following output:

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