First, please don't shout. Second if it is class that you have created simply apply the [System.Xml.Serialization.XmlIgnoreAttribute] to the properties that you don't want to show. If it is a framework class, you need to get the data from the XMLSerializer object to an XML document object for manipulation. If this is the case and you have problems with this, please post the specifics.
