Manipulating existing XDocument (fails)
- by Daemonfire3002nd
Hi there,
I got the following Code snippet from my Silverlight Application:
var messages = from message in XcurrentMsg.Descendants("message")
where DateTime.Parse(message.Attribute("timestamp").Value).CompareTo(DateTime.Parse(MessageCache.Last_Cached())) > 0
select new
{
ip = message.Attribute("ip").Value,
timestamp = message.Attribute("timestamp").Value,
text = message.Value,
};
if (messages == null)
throw new SystemException("No new messages recorded. Application tried to access non existing resources!");
foreach (var message in messages)
{
XElement temporaryElement = new XElement("message", message.text.ToString(), new XAttribute("ip", message.ip.ToString()), new XAttribute("timestamp", message.timestamp.ToString()));
XcurrentMsg.Element("root").Element("messages").Add(temporaryElement);
AddMessage(BuildMessage(message.ip, message.timestamp, message.text));
msgCount++;
}
MessageCache.CacheXML(XcurrentMsg);
MessageCache.Refresh();
XcurrentMsg is a XDocument fetched from my server containing messages:
Structure
<root>
<messages>
<message ip="" timestamp=""> Text </message>
</messages>
</root>
I want to get all "message" newer than the last time I cached the XcurrentMsg.
This works fine as long as I cut out the "XElement temporaryElement" and the "XcurrentMsg.Element...."
and simply use the currentMsg string as output.
But I want to have "new messages" being saved in my XcurrentMsg / Cache.
Now if I do not cut this part out, my Application gets awesome crazy.
I think it writes infinite elements to the XcurrentMsg without stopping.
I can not figure out what's the problem.
regards,
