Parameters

Type: Microsoft.VisualStudio.Text.ITextBuffer
The ITextBuffer that the ITextStructureNavigator will navigate.

Type: Microsoft.VisualStudio.Utilities.IContentType
The content type to use.
Return Value

Remarks
If a navigator for the given content type cannot be found, this method uses one for the parent IContentType. If there is more than one parent IContentType for which there is a matching ITextStructureNavigator, then this method returns the ITextStructureNavigator of an arbitrary parent.
The navigator that is created is not cached; subsequent calls to this method for the same buffer and content type will return different ITextStructureNavigator objects.
