I have 2 xml config files contains either:

1 :<User Server="server name" Database="database name" />

2: <User Server="server name" Database="database name" Login="login" Password="password" ReportOpenType="Preview" />

I just want to be able to extract the Server Name from the User Server="server name"

note that I have used server name etc for data protection reasons.

I would really appreciate a rapid response.

What I have tried:

I have tried this

C#

XDocument xDoc = XDocument.Load(exepath);
            //xDoc.
            string nodeValue = string.Empty;
var node = xDoc.Descendants().Where(n => n.Name == nodeName).FirstOrDefault();



                        if (node != null)
                        {
                            nodeValue = node.Value;
                        }

this works on others which have

<server>server name</server>

, but not where there is <User Server="server name" as described above.

Solution 1

Instead of getting a value, try to get the attribute:

C#

string value = xDoc.Root.Element("User").Attribute("Server").Value;

Have you try the Attribute method? I don't know what in the XML file, assuming this is the only line in the XML file.

XML

<User Server="server name" Database="database name" Login="login" Password="password" ReportOpenType="Preview" />

Here is the code to get the Server value

C#

var serverName = (from s in xDoc.Descendants("User")
                           select s.Attribute("Server").Value).FirstOrDefault ();

Output:
server name
