I'm currently working on a SilverLight text editor for my site control panel, I almost done with that, but now I need to convert XAML to Html and vice versa (as you probably know Silverlight's RichTextBox returns XAML) So I've to convert it to Html. Any idea how can I handle this ?
Well, it's just XML. So convert Section and Paragraph elements to their appropriate HTML equivalents (p and div, probably) and do so for the inlines as well (Run expands to just the text, probably, Span gets span, LineBreak gets br, etc.).
I.e. what you need to do is read the XAML as XML and create another document alongside where you write the elements as HTML. Applying formatting is a bit tricky, though, as you need to convert that to CSS styles (and maybe not everything apart from basic font properties works the same way in XAML and CSS).
This demo might be a good start: http://msdn.microsoft.com/en-us/library/aa972129(v=vs.90).aspx
It covers both conversions.
This product converts C# and XAML to HTML and JavaScript. It has a free edition that allows commercial use.
A wide range of both .NET and XAML features are supported, which can be seen here.
This tool allows you to enter XAML and have it converted to HTML, or enter HTML and have it converted to XAML.
