Try this;

DataSet ds = new DataSet();
ds.ReadXml("datafile.xml");

dataGrid.DataSource = ds;
dataGrid.DataMember = "Contact";

problem reading child by attribute

Jassim Rahma20-Mar-10 4:02

20-Mar-10 4:02

I am using this code to read one the childs using its attribule but it's always reading the first child though the selected GUID is the last child? what's the problem:

xml_documen.SelectSingleNode("/Resume/Contacts/Contact[@ID='73298407-06fa-462a-be30-254a5318176c']");

txtContactNumber.Text = xml_documen.GetElementsByTagName("Number")[0].InnerText;

Not Active20-Mar-10 4:08

20-Mar-10 4:08

You'll need to clarify a little. The problem is with the first line? how is the second line involved?

I don't see any problem with the first line, unless you have more than one contact node with the same attribute value.

You still DID NOT answer the question. What does the second line have to do with it? The first line works fine and returns the correct node.

i am sorry.. i didn't read the question Smile | :)

Actually I need to read a specific node by referring to it's attribute// that's why in this example:

xml_documen.SelectSingleNode("/Resume/Contacts/Contact[@ID='73298407-06fa-462a-be30-254a5318176c']");

I am trying to read that specific node but it's giving the result of the first node

I've tried your example and it returns the the 3rd contact node as expected.

I have some function, which makes HttpWebRequest and returns response (string).
Everything works fine except cases when it gets 502 status - Bad Gateway.
In this case try-catch block:

try
            {
                m_Rresponse = (HttpWebResponse)m_HttpWebRequest.GetResponse();
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
                if (m_Rresponse.StatusCode == HttpStatusCode.BadGateway || m_Rresponse.StatusCode == HttpStatusCode.GatewayTimeout ||
                    m_Rresponse.StatusCode == HttpStatusCode.InternalServerError || m_Rresponse.StatusCode == HttpStatusCode.ServiceUnavailable)
                {
                    Console.WriteLine("Sleeping 10 seconds...");
                    Thread.Sleep(10000);
                }
            }

The question is why In case of BadGatway "Sleeping 10 seconds..." never printed?

Thanks

Since I don't have any way of generating a 502 error, I have to assume that is does not set m_Rresponse when it throws an exception - which makes sense, since the throw instruction will terminate processing and transfer control to the catch block immediately. The documentation[^] says "If a WebException is thrown, use the Response and Status properties of the exception to determine the response from the server." which makes more sense to me than relying on an exception completing the instruction that detected the problem.

I am surprised it works for any error, not just 502!
