XNodeDocumentOrderComparer Class
Contains functionality to compare nodes for their document order. This class cannot be inherited.
Namespace: System.Xml.Linq
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
The XNodeDocumentOrderComparer type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | XNodeDocumentOrderComparer | Initializes a new instance of the XNodeDocumentOrderComparer class. |
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | Compare | Compares two nodes to determine their relative document order. |
![]() ![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
This class implements IComparer and IComparer<XNode>.
We recommend that instead of using this class directly, you use the InDocumentOrder(Of T) method. This class is used internally by that method.
The following example uses of this class to compare the document order for two nodes.
StringBuilder output = new StringBuilder(); XElement xmlTree = new XElement("Root", new XText("Text content."), new XElement("Child1", "child1 content"), new XElement("Child2", "child2 content"), new XElement("Child3", "child3 content"), new XText("More text content."), new XElement("Child4", "child4 content"), new XElement("Child5", "child5 content") ); XElement child3 = xmlTree.Element("Child3"); XElement child5 = xmlTree.Element("Child5"); XNodeDocumentOrderComparer documentOrderComparer = new XNodeDocumentOrderComparer(); int val = documentOrderComparer.Compare(child3, child5); if (val == 0) output.Append("Child3 is same as Child5" + Environment.NewLine); else if (val < 0) output.Append("Child3 is before Child5" + Environment.NewLine); else output.Append("Child3 is after Child5" + Environment.NewLine); OutputTextBlock.Text = output.ToString();
