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.
