XAttribute.Remove Method ()
Removes this attribute from its parent element.
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
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. For more information, see Mixed Declarative Code-Imperative Code Bugs (LINQ to XML).
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.
XElement root = new XElement("Root", new XAttribute("Att1", "content1"), new XAttribute("Att2", "content2"), new XAttribute("Att3", "content3") ); XAttribute att = root.Attribute("Att2"); att.Remove(); Console.WriteLine(root);
This example produces the following output:
<Root Att1="content1" Att3="content3" />
