Determines the category of content that is adjacent to a TextPointer in a specified LogicalDirection.
Assembly: PresentationFramework (in PresentationFramework.dll)

| None | The TextPointer is adjacent to the beginning or end of content. | |

// This method will extract and return a string that contains a representation of // the XAML structure of content elements in a given TextElement. string GetXaml(TextElement element) { StringBuilder buffer = new StringBuilder(); // Position a "navigator" pointer before the opening tag of the element. TextPointer navigator = element.ElementStart; while (navigator.CompareTo(element.ElementEnd) < 0) { switch (navigator.GetPointerContext(LogicalDirection.Forward)) { case TextPointerContext.ElementStart : // Output opening tag of a TextElement buffer.AppendFormat("<{0}>", navigator.GetAdjacentElement(LogicalDirection.Forward).GetType().Name); break; case TextPointerContext.ElementEnd : // Output closing tag of a TextElement buffer.AppendFormat("</{0}>", navigator.GetAdjacentElement(LogicalDirection.Forward).GetType().Name); break; case TextPointerContext.EmbeddedElement : // Output simple tag for embedded element buffer.AppendFormat("<{0}/>", navigator.GetAdjacentElement(LogicalDirection.Forward).GetType().Name); break; case TextPointerContext.Text : // Output the text content of this text run buffer.Append(navigator.GetTextInRun(LogicalDirection.Forward)); break; } // Advance the naviagtor to the next context position. navigator = navigator.GetNextContextPosition(LogicalDirection.Forward); } // End while. return buffer.ToString(); } // End GetXaml method.
