You can use this method to modify an XML tree. This method will cause events to occur.

There are many scenarios in which you might want to remove a set of attributes. 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 attributes and remove them. Instead, you should materialize them into a List<T> using the ToList<TSource> extension method. Then you can iterate over the list, removing the attributes.

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

The following example creates an element with three attributes. It then removes one of the attributes.


StringBuilder output = new StringBuilder();
XElement root = new XElement("Root",
    new XAttribute("Att1", "content1"),
    new XAttribute("Att2", "content2"),
    new XAttribute("Att3", "content3")
);
XAttribute att = root.Attribute("Att2");
att.Remove();
output.Append(root + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
