Make a Part of Text Bold inside TextBlock

I know that we can use <Run> in XAML to achieve what I am asking :

<TextBlock.Inlines>
    <Run Text="This is" />
    <Run FontWeight="Bold" Text="Bold Text." />
</TextBlock.Inlines>

Also I can do it in code behind as follows:

TextBlock.Inlines.Add(new Run("This is"));
TextBlock.Inlines.Add(new Bold(new Run("Bold Text.")));

But my problem is something different:

Suppose I have following Text in my database:

This is <b>Bold Text</b>.

Now, my Textblock is bound to a field that contains the above text in database.

I want the text between <b> and </b> to be bold. How can I achieve this?

If you want to display HTML, use a Webbrowser control.

<WebBrowser Name="myWebBrowser"/>

And in your code, pass your text like this:

myWebBrowser.NavigateToString(myHTMLString);

If not, and bold is the only thing to be done and cannot be nested, you can do it like this:

string s = "<b>This</b> is <b>bold</b> text <b>bold</b> again."; // Sample text
var parts = s.Split(new []{"<b>", "</b>"}, StringSplitOptions.None);
bool isbold = false; // Start in normal mode
foreach (var part in parts)
{
     if (isbold)
        myTextBlock.Inlines.Add(new Bold(new Run(part)));
     else
        myTextBlock.Inlines.Add(new Run(part));

     isbold = !isbold; // toggle between bold and not bold
}
