Comparing 2 xml files in C#???

[Dupont666]

Im looking to compare 2 xml files and output the changes, without using a seperate program (3rd party) to do so.

xml has a header and then repeating sections (nested nodes), this just needs a direct file compare and then specifiying the nodes that dont match.

Help please.

Could do worse than using fc to compare the files. I know its not strictly what you asked for, but you don't need to buy anything!

I think DOM is available with a COM interface. You just create an instance of a parser, collect and compare whatever you want in the tree(s), and spit out the results. Available on all platforms that would support C# (except perhaps mobile).

Perhaps you could even do it, byte by byte.

{{{
using System;
using System.IO;
using System.Xml;

public class Sample
{
public static void Main()
{
// Create the XmlDocument.
XmlDocument doc = new XmlDocument();
doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
"<title>Pride And Prejudice</title>" +
"</book>");

// Save the document to a file.
doc.Save("data.xml");
}
}
}}}

Copied form the manual.

Cheers will look at both of them, unfortunately all the examples I see are about combining files rather than comparing them.

It's the daddy of all text diff algorithms - could be worth a look, even if it's not XML-specific.
