<div>
The easiest way is to use the SelectSingleNode() method:
<pre><code class="code-1 nolinks" id="code-20-41548912-1"><span>            XmlDocument xml = new XmlDocument();</span>
<span>            xml.Load( &quot;ErrorRowsXml.xml&quot; );</span>
<span>            if( xml.SelectSingleNode( &quot;/ERROR_REPORT/ERROR_DETAIL&quot; ) != null ) </span>
<span>                Console.WriteLine(&quot;Exists&quot;);</span>
<span>            else</span>
<span>                Console.WriteLine(&quot;Does not exist&quot;);</span>
</code></pre>
</div>

Chris Stanyon and zc2,<br />
Thank you for your time and help. &nbsp;<br />
<br />
I am able to check it. &nbsp;Now, once checked, if <b>null</b> I need to add the node. &nbsp;How can I do that?<br />
<br />
Thank you

Check a Node in XML Doc in C#

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Extensible Markup Language (XML) refers to the encoding of documents such that they can be read by both machines and humans. XML documents use tags to show the beginning and end of a set of data. XML is used extensively on websites to show volumes of data, and is the default for a number of office productivity suites. This topic includes discussions of XML-related technologies, such as XQuery (the XML Query language), XPath (the XML Path language), XSLT (eXtensible Stylesheet Language Transformations), XLink (the XML Linking language) and XPointer (the XML Pointer language).

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
