Within attribute-values i can use the double quote, which is written

as "&quot;" into the document by the XML-methods of .NET:
Node Name="a&quot;b" Att1="true"/

But how to reference such nodes with an XPath-expression?
=> pXml.SelectSingleNode("//Folder[@Name=??]")

What's the correct Syntax?

With C# you can use
pXml.SelectSingleNode("//Node[@Name = 'a\"b']")
With VB.NET you can use
pXml.SelectSingleNode("//Node[@Name = '\""b']")

The real problem only occurs if the attribute value contains single
_and_ double quotes. In that case you would need to break up the string
into components.
And even for that problem there is a solution, such as using variables.
Here is a sample - http://www.tkachenko.com/blog/archives/000385.html
