Sorry I don't have time to fully try this for you but this will be closer depending on what hoSOAPxml is a handle to

Code:
            Move ("xmlns:p='http://schemas.xmlsoap.org/soap/envelope/' xmlns:wsp='WebServiceProvider'" ) to sNS
            Set psSelectionNamespaces of hoSOAPXml to sNS
            Get FindNode of hoSOAPXml "/p:Body/wsp:Product_Save/wsp:products/wsp:ProductSaveRequest" to hoParam
