Need to update a string value in XML using C#

Question

I have an XML file in which there is a particular string needs to be updated Below in XML File I have "@@key@@"

<?xml version="1.0"?>
<Movies>
  <Movie name="Ready">
    <Director>John</Director>
    <Download>http://www.youtube.com/watch?v=**@@Key@@**=relatedreadypart6</Download>
    <Price>$40</Price>
  </Movie>
</Movies>

I want to update @@key@@ with some valid Data.

Look at XmlDocument and XDocument. Then, try some things. It is just using a simple XPath Selector coupled with updating the element Value. Alternatively, just treat the entire file as a string (and use string.Replace or RegExp.Replace) since it seems like a very specialized problem. — user166390

var path = "C:\path\to\file.xml";
var markup = File.ReadAllText(path);
var new_markup = markup.Replace("@@key@@", "foo");

var doc = new XmlDocument();
doc.LoadXml(new_markup);

Load the file as string. Do a simple .Replace and then parse it as XML. new_markup is a string representation of the XML. doc is an XML representation of the XML.

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(string.replace(xmlStr, " @@key@@","your data"))
