XContainer.ReplaceNodes Method (Object)
Replaces the children nodes of this document or element with the specified content.
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
For details about the valid content that can be passed to this function, see Valid Content of XElement and XDocument Objects.
This method has snapshot semantics. It first creates a copy of the new content. It then removes all children nodes of this node. Finally, it adds the new content as children nodes. This means that you can replace children nodes using a query on the children nodes themselves.
The following example creates a dictionary and an XML tree. It then queries the dictionary, projects the results to an IEnumerable<T> of XElement, and replaces the contents of the XML tree with the results of the query.
StringBuilder output = new StringBuilder(); XElement root = new XElement("Root", new XElement("Child", 1), new XElement("Child", 2), new XElement("Child", 3), new XElement("Child", 4), new XElement("Child", 5) ); root.ReplaceNodes( from el in root.Elements() where (int)el >= 3 select el ); output.Append(root + Environment.NewLine); OutputTextBlock.Text = output.ToString();
