Removing XML Element. Simple??? Give me your trick please

[GhislainTanguay]

This is my XML file and below you will find my code to remove it... I was
thinking that it's a simple task but this code doesn't work.

Anybody have a better solution?

Here is my Code

Dim rotatorDom As New XmlDocument()

rotatorDom.Load (rotatorFile)

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

settings.PassTh roughPage & "?AD=" & _

advertisementId .ToString() & """]"

rotatorDom.Load (rotatorFile)

Dim currentAd As XmlNode = _

CType(rotatorDo m.DocumentEleme nt.SelectSingle Node(xPathFind) , XmlNode)

rotatorDom.Docu mentElement.Rem oveChild(curren tAd)

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>X ML</MainCategory>
<Description>Th is is a list my XML
articles.</Description>
<Active>true</Active>
</Category>
</CategoryList>

Code:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Ser ver.MapPath("ca tegories.xml")) ;

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

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

xmlDoc.Save(Ser ver.MapPath("ca tegories.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(Ser ver.MapPath("ca tegories.xml")) ;
