Hi,
The posted code above was a great help. I transformed it into C# in a VS2003 project and thought it might be helpful:
Thanks!

// CUSTOM Method: SetNil
// Needed because of the xml and form validation rules on certain fields like DateTime, Boolean, etc.
public void SetNil(IXMLDOMNode node)
{
if( node.text == "")
{ return; }
IXMLDOMElement nilElement;
IXMLDOMAttribute nilAttribute;

// Create an element and an attribute for xsi:nil with the proper namespace.
nilElement = (IXMLDOMElement)node;
nilAttribute = (IXMLDOMAttribute)node.ownerDocument.createNode((int)DOMNodeType.NODE_ATTRIBUTE,"xsi:nil",xsiNS);
nilAttribute.text = "true";

// The order is important
node.text = String.Empty;
nilElement.setAttributeNode(nilAttribute);
}

This might be helpful:

/*------------------------------------------------------------------------------
	setNil() - Empty a nillable element.
------------------------------------------------------------------------------*/
function setNil(xpath)
{
	var xmlNode = getNode(xpath);

	if (!xmlNode || xmlNode.text === "")
		return;

	// Create xsi:nil attribute with the proper namespace.
	var xmlNil = xmlNode.ownerDocument.createNode(2, "xsi:nil", "http://www.w3.org/2001/XMLSchema-instance");
	xmlNil.text = "true";

	// The order is important.
	xmlNode.text = "";
	xmlNode.setAttributeNode(xmlNil);
}

Hi Delu,
Check out the jscript code in the samples that ship with InfoPath. They have the same issue and solve it in code.

Add attribute

Hi there.

I want to set a date picker to a date. I read I have to remove the nil attribute in order to do that. This works great, *but* the date picker is then set to can not be blank.
How can I readd the attribute in case the user wants to remove the date?

Thanks!
