Fields

Name Value Description
Auto 0

Default. Chooses the comparison algorithm for you depending on the size and assumed number of changes in the compared documents.

Fast 1

Compares the two XML documents by traversing the XML tree and comparing it node-by-node. This algorithm is very fast but may produce less precise results. For example, it may detect both an add and remove operation on a node instead of a move operation.

Precise 2

Compares files based on an algorithm for finding the editing distance between trees, also known as Zhang-Shasha algorithm. This algorithm gives very precise results but it may be very slow on large XML documents with many changes.

Examples

Imports System  
Imports System.Xml  
Imports Microsoft.XmlDiffPatch  

Namespace TestCompare  
   Class Class1  
      Shared Sub Main()  
        Dim diffWriter = New XmlTextWriter("diffgram.xml", New System.Text.UnicodeEncoding())  
        Dim myDiff As New XmlDiff()  
        myDiff.Algorithm = XmlDiffAlgorithm.Precise  
        Dim bSame As Boolean = myDiff.Compare("source.xml", "changed.xml", False, diffWriter)  
        Console.WriteLine("The answer is {0} ", bSame)  
      End Sub  
   End Class  
End Namespace  
using System;  
using System.Xml;  
using Microsoft.XmlDiffPatch;  

namespace TestCompare  
{  
  class Class1  
    {  
        static void Main()  
            {  
            XmlWriter diffWriter = new XmlTextWriter("diffgram.xml", new System.Text.UnicodeEncoding());   
            XmlDiff myDiff = new XmlDiff();  
            myDiff.Algorithm = XmlDiffAlgorithm.Precise;  
            bool bSame = myDiff.Compare("source.xml", "changed.xml", false, diffWriter);  
    Console.WriteLine("The answer is {0} ", bSame);  
            }  
    }  
}
