Issue relating to XmlDiffPatch

Question

Hello buddies,

 

This is Arati, am working as Software Developer in Siemens Information Systems Ltd. Bangalore, India.

I have been working on Microsoft .Net Technologies since 2 years.

 

Now... I have got one issue regarding Microsoft's XmlDiffPatch and I found no related articles.

I am using Microsoft's XmlDiffPatch component in my application(VS 2003 with Framework 1.1) to compare two XML files. I am getting an exception which is as follows (Exception.StackTrace):

 

 at Microsoft.XmlDiffPatch.XmlDiff.PreprocessNode(XmlDiffNode node, XmlDiffNode[]& postOrderArray, Int32& currentIndex)
 at Microsoft.XmlDiffPatch.XmlDiff.PreprocessNode(XmlDiffNode node, XmlDiffNode[]& postOrderArray, Int32& currentIndex)
 at Microsoft.XmlDiffPatch.XmlDiff.PreprocessTree(XmlDiffDocument doc, XmlDiffNode[]& postOrderArray)
 at Microsoft.XmlDiffPatch.XmlDiff.ZhangShashaAlgorithm()
 at Microsoft.XmlDiffPatch.XmlDiff.Diff(XmlWriter diffgramWriter)
 at Microsoft.XmlDiffPatch.XmlDiff.Compare(XmlNode sourceNode, XmlNode changedNode, XmlWriter diffgramWriter)

 

There is no much information available on the net regarding disadvantages and cuts of XmlDiffPatch.

 

Below is the code segment which I have written to compare two files.

XmlDocument xDiff = new XmlDocument();

StringBuilder sb = new StringBuilder();

StringWriter s = new StringWriter(sb);

XmlTextWriter xr = new XmlTextWriter(s);

//m_diffengine.Algorithm = XmlDiffAlgorithm.Precise;

bool cSuccess = m_diffengine.Compare(xOld, xNew, xr);

Console.WriteLine(cSuccess.ToString());

//xDiff.LoadXml(sb.ToString());

 

Could you please help me out in this case?

 

Thanks in advance.
