You need to use XMLDocument object in which XML is parse while loading.
see below snippet


XMLDocument objDom;
Try
{
   objDom = new XMLDocument();
   objDom.LoadXml("xml string");
}
Catch (Exception ex)
{
   //error occurred while parsing xml
   string szError = ex.Message;
}
Finally
{
   objDom = null;
}

hope it helps

Open the XML in IE if the file is opened then there is no error other wise it will show the error.

You can also make use of the XML document object in code to check.

if the Object is loaded there will not be error other wise you will get the error.


XMLDocument xDoc = new XMLDocument("Ur file Name here);

Hai Nileash,
To validate your XML, first you need to generate the Schema Definition(XSD) for your XML.
Once you have the XSD, you can easily validate each of the node which is generated in your XML document.
Please find the below article to generate the schema definition and then validate the incoming XML:

Hope it will be helpful to you.
