Xml serialization attribute for nested List

[chrisfost]

Is it possible by using attributes to serialize a <List<List<Poin t>>
property to output as shown below?

Current Output

<PolyPolyline >
<ArrayOfPoint >
<Point>
<X>5</X>
<Y>5</Y>
</Point>
<Point>
<X>10</X>
<Y>15</Y>
</Point>
Preferred Output

<PolyPolyline >
<Polyline>
<Point X=5 Y=5 />
<Point X=10 Y=15 />
Here is some sample code of the class:

--------------------------------------------------------------

using System.Drawing;
using System.Collecti ons.Generic;
using System.Xml;
using System.Xml.Seri alization;

namespace Cjf
{
public class Test
{
private List<List<Point >_polyPolylin e = new
List<List<Point >>();

public List<List<Point >PolyPolyline
{
get { return _polyPolyline; }
set { _polyPolyline = value; }
}

public static void Serialize(strin g filename, Test test)
{
XmlSerializer serializer = new XmlSerializer(t ypeof(Test));

XmlWriter writer = XmlWriter.Creat e(filename);
serializer.Seri alize(writer, test);
writer.Close();
}

public static Test Deserialize(str ing filename)
{
XmlSerializer s = new XmlSerializer(t ypeof(Test));

XmlReader reader = XmlReader.Creat e(filename);
Test test = (Test)s.Deseria lize(reader);
reader.Close();

return test;
}

public static Test CreateTestData( )
{
Test test = new Test();

List<Pointpolyl ine = new List<Point>();
test.PolyPolyli ne.Add(polyline );
polyline.Add(ne w Point(5, 5));
polyline.Add(ne w Point(10, 15));
polyline.Add(ne w Point(20, 15));
polyline.Add(ne w Point(25, 30));

polyline = new List<Point>();
test.PolyPolyli ne.Add(polyline );
polyline.Add(ne w Point(-5, -5));
polyline.Add(ne w Point(-10, -15));
polyline.Add(ne w Point(-20, -15));

return test;
}
}
}
-------------------------------------------------------------

string path = System.IO.Path. GetTempPath();

Cjf.Test test = Cjf.Test.Create TestData();
Cjf.Test.Serial ize(path + "test1.xml" , test);

Why not just break your code out into multiple serializable classes and use
properties to reference the child elements/attributes?

[XmlRoot{"PolyPo lyline")]
public class PolyPolyline
{
private List<ArrayOfPoi ntmlArrayOfPoin t = new List<ArrayOfPoi nt>();

[XmlElement("Arr ayOfPoint")]
public List<ArrayOfPoi ntArrayOfPoint
{
get mlArrayOfPoint ;
set mlArrayOfPoint;
}
}

public class ArrayOfPoint
{
private Point mpPoint;

[XmlElement("Poi nt")]
public Point Point
{
get mpPoint;
set mpPoint;
}
}

public class Point
{
private int miX;
private int miY;

[XmlAttribute("X ")]
public int X
{
get miX;
set miX;
}
[XmlAttribute("X ")]
public int Y
{
get miY;
set miY;
}
}
