Question

How to test whether a node contains particular string or character using C# code.

example:

<abc>
  <foo>data testing</foo>
  <foo>test data</foo>
  <bar>data value</bar>
</abc>

Now I need to test the particular node value has the string “testing” ?

The output would be “foo[1]”

You can also that into an XPath document and then use a query:

var xPathDocument = new XPathDocument("myfile.xml");
var query = XPathExpression.Compile(@"/abc/foo[contains(text(),""testing"")]");

var navigator = xpathDocument.CreateNavigator();
var iterator = navigator.Select(query);

while(iterator.MoveNext())
{
    Console.WriteLine(iterator.Current.Name);    
    Console.WriteLine(iterator.Current.Value);    
}
