Remarks

In LINQ to XML programming, you should not manipulate or modify a set of nodes while you are querying for nodes in that set. In practical terms, this means that you should not iterate over a set of nodes and remove them. Instead, you should materialize them into a List<T> by using the ToList<TSource> extension method. Then, you can iterate over the list to remove the nodes. For more information, see Mixed Declarative Code/Imperative Code Bugs (C#) (LINQ to XML).

Alternatively, if you want to remove a set of nodes, it is recommended that you use the Extensions.Remove method. This method copies the nodes to a list, and then iterates over the list to remove the nodes.

This method will raise the Changed and the Changing events.

Examples

The following example removes a node from its parent.

XElement xmlTree = new XElement("Root",
    new XElement("Child1", "child1 content"),
    new XElement("Child2", "child2 content"),
    new XElement("Child3", "child3 content"),
    new XElement("Child4", "child4 content"),
    new XElement("Child5", "child5 content")
);
XElement child3 = xmlTree.Element("Child3");
child3.Remove();

Dim xmlTree As XElement = _ 
        <Root>
            <Child1>child1 content</Child1>
            <Child2>child2 content</Child2>
            <Child3>child3 content</Child3>
            <Child4>child4 content</Child4>
            <Child5>child5 content</Child5>
        </Root>

Dim child3 As XElement = xmlTree.<Child3>(0)
child3.Remove()
