Here is my Code

Dim rotatorDom As New XmlDocument()

rotatorDom.Load(rotatorFile)

Dim xPathFind As String = "//Ad[NavigateUrl=""" & _

settings.PassThroughPage & "?AD=" & _

advertisementId.ToString() & """]"

rotatorDom.Load(rotatorFile)

Dim currentAd As XmlNode = _

CType(rotatorDom.DocumentElement.SelectSingleNode(xPathFind), XmlNode)

rotatorDom.DocumentElement.RemoveChild(currentAd)

My file still jam with this element!!!! Nothing changes

I might be wrong but the caller of RemoveChild must be his
parent. I created a small example to demonstrate this:

XML:

<?xml version="1.0" encoding="utf-8"?>
<CategoryList>
<Category ID="01">
<MainCategory>XML</MainCategory>
<Description>This is a list my XML
articles.</Description>
<Active>true</Active>
</Category>
</CategoryList>

Code:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Server.MapPath("categories.xml"));

XmlNode node = xmlDoc.SelectSingleNode
("/CategoryList/Category[@ID='01']");
XmlNode commonParent = node.ParentNode;

if(node != null)
{
commonParent.RemoveChild(node);
}

xmlDoc.Save(Server.MapPath("categories.xml"));

Well tks buddy,
My code is good except that didn't save my change after updating my file
All I needed is
xmlDoc.Save(Server.MapPath("categories.xml"));

Tks again
