Title Body

Is there a way to search an XDocument without knowing the namespace? I have a process that logs all SOAP requests and encrypts the sensitive data. I want to find any elements based on name. Something like, give me all elements where the name is CreditCard. I don't care what the namespace is. My problem seems to be with LINQ and requiring a xml namespace. I have other processes that retrieve values from XML, but I know the namespace for these other process. XDocument xDocument = XDocument.Load(@"C:\temp\Packet.xml"); XNamespace xNamespace = "http://CompanyName.AppName.Service.Contracts"; var elements = xDocument.Root .DescendantsAndSelf() .Elements() .Where(d => d.Name == xNamespace + "CreditCardNumber"); I really want to have the ability to search xml without knowing about namespaces, something like this: XDocument xDocument = XDocument.Load(@"C:\temp\Packet.xml"); var elements = xDocument.Root .DescendantsAndSelf() .Elements() .Where(d => d.Name == "CreditCardNumber") This will not work because I don't know the namespace beforehand at compile time. How can this be done? <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Request xmlns="http://CompanyName.AppName.Service.ContractA"> <Person> <CreditCardNumber>83838</CreditCardNumber> <FirstName>Tom</FirstName> <LastName>Jackson</LastName> </Person> <Person> <CreditCardNumber>789875</CreditCardNumber> <FirstName>Chris</FirstName> <LastName>
