Overloads

ElementsBeforeSelf()

Returns a collection of the sibling elements before this node, in document order.
ElementsBeforeSelf(XName)

Returns a filtered collection of the sibling elements before this node, in document order. Only elements that have a matching XName are included in the collection.

XNode.cs

Returns a collection of the sibling elements before this node, in document order.

public:
 System::Collections::Generic::IEnumerable<System::Xml::Linq::XElement ^> ^ ElementsBeforeSelf();
public System.Collections.Generic.IEnumerable<System.Xml.Linq.XElement> ElementsBeforeSelf();
member this.ElementsBeforeSelf : unit -> seq<System.Xml.Linq.XElement>
Public Function ElementsBeforeSelf () As IEnumerable(Of XElement)

Returns

IEnumerable<XElement>

An IEnumerable<T> of XElement of the sibling elements before this node, in document order.

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.

This method uses deferred execution.

);
XElement child = xmlTree.Element("Child3");
IEnumerable<XElement> elements = child.ElementsBeforeSelf("Child2");
foreach (XElement el in elements)
    Console.WriteLine(el.Name);

Dim xmlTree As XElement = _
        <Root>Text content.
