title: XmlDocument InnerXml Formatting
body: <p>I have a document on which I'm replacing the inner XML of some node:</p>
  
  <pre><code>    var xmlReplacement = File.ReadAllText(path); // this xml is well formatted with indentations itself, but not indented at the correct level for the document it's about to be inserted into
  
      var document = new XmlDocument();
      document.PreserveWhitespace = true;
      document.Load(path);
  
      // replace inner xml of ContainingNode
      var node = document.SelectSingleNode("//ContainingNode");
      node.InnerXml = xmlReplacement;
  
      // write back to the output file
  using (var writer = new XmlTextWriter(path, null))
  {
      writer.Formatting = Formatting.Indented;
      document.WriteTo(writer);
  }
  </code></pre>
  
  <p>I end up getting the new inner xml non-indented (all the way to the left) and the close node  on the same line as the close of my replacement xml's node.</p>
  
  <p>How can I get this right?</p>
