Conditional XML serialization?? ?

Hi,

I've got two classes - Entity which will have an array of Child objects
in it and Child class.

class Entity
{

public Child[] Children;

}

class Child
{

public string Name;
public string Description;

}

I want to be able to serialize this class into two different XMLs.

1) looks like,
<Entity>
<Child Name="" Description=""/>
<Child Name="" Description=""/>
<Child Name="" Description=""/>
</Entity>

2) looks like,
<Entity>
<Child Name=""/>
<Child Name=""/>
<Child Name=""/>
</Entity>

How to do this? Coz If I use [XmlIgnore] attribute on class Child's
description attribute, then it won't allow me to produce Xml (1).
So its basically to control serialization during runtime.

My serialization code currently looks like,

// Serialize the Entity object in to an XML document, and we are done.
TextWriter objTextWriter = null;
XmlSerializer objXmlSerialize r = new
XmlSerializer(t ypeof(Entity));
objTextWriter = new StreamWriter(@" C:\Entity.xml") ;
objXmlSerialize r.Serialize(obj TextWriter, objEntity);

Any help in this regard would be of great help. MS experts help me out
here... please..

Cheers,
Vin

How about modifying your code to:

class Child
{
public string Name;
public string Description;
[XmlIgnore]
public bool DescriptionSpec ified;
}

The framework serialization process checks for a Boolean field with the same
name as each field but suffixed with "Specified" . If such a Boolean field
exists, it will only serialize the original field if the Boolean field's
value is 'true'.

Hello, I've been just investigating IE conditional comments - hiding things from non-IE/Win browsers is easy, but I wanted to know, if it's possible to hide code from IE/Win browsers.
