Does anybody know a simple way to remove the XAML xml information from a
styled item ?
I have a listbox with XAML formatted entries and need to get the
text which is displayed in the listbox only !

I have this if it helps.

Function TextFromXAML(sXaml As String) As String
Dim find%
Dim p
Dim txt As String
find% = InStr(sXaml, "</Run")

If find% <= 0 Then find% = InStr(sXaml, "</TextBlock")

            If find% > 0 Then
                txt = Left(sXaml, find% - 1)
                    p = Split(txt, ">")
                        txt = CStr(p(UBound(p)))
                            TextFromXAML = txt
            End If
End Function

It turns out that this is a trickier problem than it first appears! For example, Boris' method fails if the TextBlock contains <LineBreak/> tags, or if the TextBlock has been defined like:

<TextBlock Text='This is a test'/>

It also won't reverse entity encodings such as & and £ . It is still a very useful function as long as you keep your XAML within a specific definition though (I'm not knocking it, just pointing out some potential pitfalls).

I'm working on a more general algorithm now, and I will post it when it is available.

Hi jpbro,

I have been a little lazy. This was a piece of code that I use to split out the known elements I have used to add to combos amd list boxes in one of my apps. If you do come up with a more global version I would like to see this as I have only coded this for my own specific needs. But, it does show that CJ could add a very useful property to some of the controls.

CJ are you reading this?

Best regards,

That looks fairly compreshensive!

Well done.

If I need to use a lot more XML in my lists I'll definately try using this rather than my version.

Thanks jpbro

Thanks Boris!

I just made a few bug fixes and re-uploaded the source to the same post as before...I hope it comes in handy some day!
