How to bind linesements point to xml data in WPF

[truel]

I have some data

<Array>
    <Element Value="30"/>
    <Element Value="50"/>
    <Element Value="10"/>
</Array>

Now I want to create a curve using this data. I think to use the LineSegments. But I can't understand how to bind the LineSegment Points to this data?

I mean, is there any syntax that helps to write instead of

<GeometryDrawing.Geometry>
  <PathGeometry>
    <PathFigure>
      <LineSegment Point="0,30"/>
      <LineSegment Point="20,50"/>
      <LineSegment Point="40,10"/>
    </PathFigure>
  </PathGeometry>
</GeometryDrawing.Geometry>

something like this:

<GeometryDrawing.Geometry>
  <PathGeometry>
    <PathFigure>
      <LineSegment Point={Binding ????}/>
    </PathFigure>
  </PathGeometry>
</GeometryDrawing.Geometry>

The main problem is how to bind the coordinates to point structure of a linesegment using binding.

Thanks in advance!
