[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Compares the values of two nodes.
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
Parameters
- x
- Type: System.Xml.Linq.XNode
The first XNode to compare.
- y
- Type: System.Xml.Linq.XNode
The second XNode to compare.
Implements
IEqualityComparer(Of T).Equals(T, T)The following criteria determine whether two nodes are equal:
A Nothing node is equal to another Nothing node but unequal to a non-Nothing node.
Two XNode objects of different types are never equal.
Two XText nodes are equal if they contain the same text.
Two XElement nodes are equal if they have the same tag name, the same set of attributes with the same values, and (ignoring comments and processing instructions), contain two equal-length sequences of pairwise equal content nodes.
Two XDocument objects are equal if their root nodes are equal.
Two XComment nodes are equal if they contain the same comment text.
Two XProcessingInstruction nodes are equal if they have the same target and data.
Two XDocumentType nodes are equal if the have the same name, public ID, system ID, and internal subset.
The following example uses this class to compare two nodes.
StringBuilder output = new StringBuilder(); XElement xmlTree1 = new XElement("Root", new XAttribute("Att1", 1), new XAttribute("Att2", 2), new XElement("Child1", 1), new XElement("Child2", "some content") ); XElement xmlTree2 = new XElement("Root", new XAttribute("Att1", 1), new XAttribute("Att2", 2), new XElement("Child1", 1), new XElement("Child2", "some content") ); XNodeEqualityComparer equalityComparer = new XNodeEqualityComparer(); output.Append(equalityComparer.Equals(xmlTree1, xmlTree2) + Environment.NewLine); xmlTree2.Add(new XElement("NewChild", "new content")); output.Append(equalityComparer.Equals(xmlTree1, xmlTree2) + Environment.NewLine); OutputTextBlock.Text = output.ToString();
