Return Value

Type: System.Collections.Generic.IEnumerable<XElement>
An IEnumerable<T> of XElement of the sibling elements before this node, in document order.

This method only includes siblings in the returned collection. It does not include descendants.

The following example uses this axis method.

XElement xmlTree = new XElement("Root",
    new XText("Text content."),
    new XElement("Child1", "child1 content"),
    new XElement("Child2", "child2 content"),
    new XElement("Child3", "child3 content"),
    new XText("More text content."),
    new XElement("Child4", "child4 content"),
    new XElement("Child5", "child5 content")
);
XElement child = xmlTree.Element("Child3");
IEnumerable<XElement> elements = child.ElementsBeforeSelf();
foreach (XElement el in elements)
    Console.WriteLine(el.Name);

This example produces the following output:

Child1
