Examples
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);
Dim xmlTree As XElement = _
<Root>Text content.
<Child1>child1 content</Child1>
<Child2>child2 content</Child2>
<Child3>child3 content</Child3>More text content.
<Child4>child4 content</Child4>
<Child5>child5 content</Child5>
</Root>
Dim child As XElement = xmlTree.<Child3>(0)
Dim elements As IEnumerable(Of XElement) = child.ElementsBeforeSelf()
For Each el In elements
Console.WriteLine(el.Name)
Next
This example produces the following output:
Child1
Child2
Remarks
This method only includes siblings in the returned collection. It does not include descendants.
