Hi sippyuconn,
From your description, I understand that you want to store some XML format
data via the AppSettings <item> in .net application's configuration file,
correct?
Based on my experience, it is not quite recommended that we store such
complex format text in the appsettings. this is because AppSettings <item>
use attribute to hold item value, which is designed to store some simple
text values.
If you do want to store complex XML data into the attribute field. I think
you can consider the following means:
1. First, your xml data have to be encoded into a safe format(which won't
violate the container xml document). One simple means is using HtmlEncode
to encode the embeded xml(which is to put into appsetting item).
2. When you read the item out, you need to HtmlDecode it.
Here are two simple functions demonstrate this:
=============================
static void StoreXML()
{
XmlDocument doc = new XmlDocument();
doc.LoadXml(@"<root><items>
<item id ='1'></item><item id='2'></item>
</items>
</root>
");
Configuration config
=ConfigurationManager.OpenExeConfiguration( ConfigurationUserLevel.None);
doc.PreserveWhitespace = false;
StringWriter sw = new StringWriter();
doc.Save(sw);
config.AppSettings.Settings["doc1"].Value = null;
config.AppSettings.Settings["doc1"].Value =
HttpUtility.HtmlEncode(sw.ToString());
config.Save();
}
static void ReadXML()
{
string rawdoc = ConfigurationManager.AppSettings["doc1"];
XmlDocument doc = new XmlDocument();
string xml = HttpUtility.HtmlDecode(rawdoc);
doc.LoadXml(xml);
Console.WriteLine(doc.OuterXml);
}
=========================
Hope this helps.
Sincerely,
Steven Cheng
