how to represent \r or \n or \t in XML and read them back correctly using XmlDocument

Question

For example:

<codes>\n\r\t</codes>

When I read the node "codes" in a string, it should contain the 3 characters '\n', '\r', '\t' as if it was s="\n\r\t";

Answer 1

You could use hexadecimal character entities:

<codes>&#xA;&#xD;&#x9;</codes>
