Not clear, what's the problem? What did you try so far? You have .NET XML parsers, you have RichTextBox (what's it the exact type? there are more then one under this name...), fully documented. So, what kind if help do you need?

Yeah, it's not sure. If you have problems working with XML try to search for some infos on XmlDocument.
As far as I know, you can work with some kind of selection on your RichtextBox. So you append your text to the box, then you select it via code and format the selected text.

You can use LINQ to XML ( which is best ) or the XmlDocument class ( which requires more code ) to get the value out of your XML.

Here[^]

My guess:

XML

IEnumerable<string> text =
    from item in doc.Descendants("text")
    select (string) item.Attribute("PartNumber");

I am not sure if you need to reference the top level element or not. Of course you need to load the XDocument with your file first.

First convert the text to xml file and do the following code

C#

 var textConfiguration = XDocument.Load(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Config.xml")); 
if (textConfiguration != null) 
{ 
textConfiguration.Descendants("Configuration").Descendants("text").ToList().ForEach(text => 
{ 
font = text.Attribute("font").Value; 
color = text.Attribute("color").Value; 
fontsize = text.Attribute("font-size").Value; 
textToAppend = text.Value; 
richTextBox1.SelectionColor = Color.FromName(color); 
richTextBox1.SelectionFont = new Font(font, int.Parse(fontsize), FontStyle.Regular); 
richTextBox1.AppendText(textToAppend); 
}); 
}
