问题
I am looking for a Silverlight text editor control that provides XML syntax highlighting. I found a few answers in Winforms or WPF, like here on Stackoverflow, but I didn't manage to convert them to Silverlight. The fact that Silverlight is missing System.Drawing is probably a big problem.
The only text editor I found for Silverlight is RichTextEdit on Codeplex, but I don't think it is a suitable base for real-time syntax highlighting.
Has anyone heard of such a control, or can provide hints on how to build one? Many thanks,
Romain

I finally found that control I was looking for! SL2TextBoxWsSynParser
EDIT: This control does not seem to be updated anymore, but a new syntax-highlighting control has surfaced:
It is available here, and used on the CoderProof website.

Actipro Software has a syntax highlighter component for Winforms, WPF, and Silverlight:

I thought this was an interesting question, but you've had no answer.
I don't know of an existing control.
I've built a control to edit XHTML, but it too uses System.Drawing rather than WPF (and therefore isn't for Silverlight).
WPF is probably at least as capable as System.Drawing, but I don't know it.
Hints on how I built it:
- Define a DOM (a vanilla System.Xml.XmlDocument might suit you)
- Parse a document to instantiate a DOM
- Define a user control (with scroll bars)
- Pass the DOM instance to the user control
- In the control's 'paint' method, paint the visible fraction of the DOM
- Implement support for mouse and key presses
If you really want hints on how to build one, ask something more specific.

Hi & thanks for your answer!
Unfortunately, while WPF has drawing capabilities, Silverlight runs a very restricted set of the CLR. Painting the user control looks like quite a difficult task.
However it has been done before with this Rich text editor for Silverlight. I will see if I manage to use similar techniques to render the XML document.
One question though: is the user control fast enough to render the DOM on the fly, as the user makes changes?
