如何向XML添加属性

Question

I am returning an object from a web service. It arrives in XML format -

<DailyTracker xmlns="http://schemas.datacontract.org/2004/07/MSI.Web.MSINet.BusinessEntities">
  <ClientId>2147483647</ClientId>
  <ClientRosterId>2147483647</ClientRosterId>
  <Dept>
    <DepartmentID>2147483647</DepartmentID>
    <DepartmentName>String content</DepartmentName>
    <EmailAddress>String content</EmailAddress>
    <Location>2147483647</Location>
    <PayCode>String content</PayCode>
  </Dept>
etc, etc...
</DailyTracker>

This is coming from an asp.net website using c#. I am returning an object of type DailyTracker. how can I add an attribute to one of the elements? Is that possible? Thanks!

Answer 1

Instantiate an XDocument using the XML returned from the service. Get the XElement that you want, then add a new XAttribute to it:

XDocument document = new XDocument(xmlString);
XElement element = document.Element("myElement");
element.Add(new XAttribute("MyAttr", "My Value"));

您可以覆盖序列化过程，并向序列化XML内容添加自定义属性，类似于此处描述的内容。
